How To Measure Screw Thread Size?

You wouldn't believe how deep the rabbit hole goes with screw heads! I got obsessed after trying to fix a squeaky chair last summer. Flatheads are the classic single slot—simple but prone to cam-out. Phillips (that cross shape) are everywhere, though they strip easier than Torx (those star-shaped ones). Then there's hex heads (Allen wrenches), square drives (less common but great for torque), and even weird ones like tri-wing for electronics. My personal favorite? Robertson squares—used heavily in Canada. They grip like a dream and don't strip. Found a vintage set at a flea market and now I'm that person who lectures friends about fastener history. Who knew screws could be so fascinating?

Figuring out your bra size can feel like solving a puzzle, but once you get the hang of it, it’s pretty straightforward. First, grab a soft measuring tape and measure around your ribcage right under your bust—make sure it’s snug but not tight. That number gives you your band size. If it’s an odd number, round up. Next, measure around the fullest part of your bust while standing straight. The difference between this number and your band size determines your cup size. Each inch represents a cup (1 inch = A, 2 = B, etc.). Keep in mind that sizes can vary between brands, so don’t stress if you need to try a few before finding the perfect fit. I’ve had friends swear by one size only to discover another brand fits completely differently. And if you’re between sizes, it’s usually better to size up for comfort. Bras shouldn’t dig into your skin or leave red marks—comfort is key!

Growing up, my dad was a stickler for precision, so I learned early on how to use a ruler properly. The key is to align the object's edge exactly with the '0' mark—not just close, but perfectly flush. If you start measuring from the 1-inch mark, you'll always be off by an inch unless you subtract it later, which is just asking for mistakes. For smaller measurements, I squint to see those tiny lines between the numbers; sometimes, a magnifying glass helps if the markings are super fine. And don’t press the ruler too hard against the object, or you might smudge the lines or even bend the ruler slightly. Another trick is lighting. Shadows can make it tricky to see where the edge of the object lines up with the ruler. I usually hold it under a bright lamp or tilt it to avoid glare. If I’m measuring something round, like a pipe, I use a flexible tape measure instead—rulers don’t bend, so they’ll give you an inaccurate reading. Oh, and always double-check! I’ve botched DIY projects before by assuming my first measurement was right. Now, I measure twice, cut once, as the old saying goes. It’s satisfying when everything lines up just right, like fitting puzzle pieces together.

Learning to read a ruler is one of those skills that seems simple but trips people up at first. I struggled with it too until I realized it’s all about breaking it down. For inches, the big numbers mark whole inches, and the smaller lines between them are fractions—halves, quarters, eighths, and sixteenths. The longest line halfway between inches is the half-inch mark, the next longest are quarter inches, and so on. Centimeters are easier because they’re divided into 10 millimeters each, with smaller lines for every millimeter. What helped me was practicing by measuring random objects around the house—pencils, books, even my phone. Over time, I started recognizing the fractions instinctively. A pro tip: rulers often have inches on one side and centimeters on the other, so double-check which side you’re using! It’s satisfying once you get the hang of it, like unlocking a tiny superpower for DIY projects or crafts.

Whoa — if you judge Johnny S. strictly by the raw count of credited appearances, he's massive, but it takes a little unpacking to make sense of that size. From what I track, his catalog stretches into the high hundreds and, depending on how you count scenes versus releases, can be pushed into the low thousands. Adult performers often accumulate credits very differently from mainstream film actors: individual scenes, compilations, re-releases, and site-specific credits all pad the numbers. Then you add his social media content, cameo-style mainstream bits, and branded collaborations, and the total footprint looks even larger. What I love about this is how numbers only tell part of the story — the cultural footprint, memeability, and crossover into normal internet culture matter too. So yeah, by filmography size he's enormous, but by influence he's got an outsized, almost paradoxical presence that goes beyond any tally — kind of wild and strangely impressive.

To cut through the myths, I started paying attention to the same red flags most folks learn the hard way: incentives, measurement technique, and optics. I used to lurk in forums and read interviews where performers casually toss out numbers like plot points, and what became obvious is that there’s a huge gap between casual claims and reproducible, clinical measurement. In entertainment industries, numbers sell—producers market personas, fans share screenshots, and performers sometimes repeat figures because it’s part of branding. That means self-reported sizes are often inflated, selectively quoted, or framed in the most flattering state (full erection, post-pump, glued-to-camera, etc.). Beyond motivation, the way something is measured matters a ton. Medical studies typically measure from the pubic bone to the tip along the top of the shaft with the penis pressed flush to the bone; that’s the most standardized method. In contrast, on-camera measurements—or casual mentions—may mean skin-to-tip, flaccid stretched, or even include prosthetics and padding. Lighting, camera angles, foreshortening, and digital zoom can all make things appear larger. There are also tricks like shaving or oiling the pubic area to reduce the visible fat pad, using angled shots that exaggerate foreground objects, or simply editing. When you add in selective reporting (only the most extreme examples get promoted) and occasional outright fabrication, reliability drops sharply. So how accurate are the reports? If you’re looking at scientific literature and controlled clinical measurements, they’re reasonably accurate within the study’s methodology and sample. If you’re looking at promotional materials, social media claims, or casual interviews tied to adult entertainment, treat them as marketing copy with a grain (or a handful) of salt. If you care about truth for comparison’s sake, seek sources that describe how the measurement was taken, what state (flaccid/erect) it was, and how big the sample was. Personally, I still enjoy the stories and performances without placing too much stock in the numbers — they make for fun conversation, but not reliable data in most non-clinical contexts.

I've collected hardware for layouts long enough to have a small toolbox full of mystery screws, and what I usually tell folks is: measure first, but here's the practical map I use. For tiny scales like Z and N I reach for the smallest hardware: think metric M1.6–M2 or imperial #2-56 where needed. These are for body screws, couplers, and very shallow mounting into plastic or thin brass. HO is the most common and forgiving: M2.5 or M3, or the imperial #4-40 and sometimes #2-56 for fiddly bits. Those sizes handle most track clips, sleeper screws, and little turnout motors. If you step up to O and G scales, you move into M3–M4 and #6-32 territory, or even standard wood screws for heavy outdoor garden-rail setups. Head style and length matter as much as diameter. Use countersunk screws where the track rail chairs or ties are designed for them, round or pan heads where you need to sit on top of roadbed, and small washers or nylon-insert nuts under layouts to prevent loosening. For baseboard attachment of track I often use short wood screws: roughly 3/8" to 1/2" (10–13 mm) for HO into plywood, a bit shorter for cork or foam. For absolute reliability I tap holes and use threaded inserts or tiny nuts on the underside — over-tightening ruins plastic ties fast. I like to keep a mixed kit of #2-56, #4-40, #6-32 and M2/M2.5/M3 screws on hand so I can match whichever track or rolling stock I pick up at a swap meet. It saves mass panic when something falls apart mid-build — and feels oddly satisfying to fix.

Lately I've been thinking about those online intimate size calculators and how confidently they promise a perfect fit. From my experience, they can be surprisingly helpful as a starting point, but they're rarely spotless predictors of real measurements. Most calculators take a couple of inputs — like waist, hip, chest, or band measurements — and map them to size charts that are built on averages. That works fine when your body matches the sample population and the brand's sizing logic, but people rarely fit averages exactly. In real life, measurements fluctuate. Time of day, hydration, recent meals, menstrual cycle, and even the tape measure placement change results. Different brands interpret sizes differently, and fabrics behave — stretchy knits versus unyielding denim give completely different fits. For intimate items specifically, fit preference matters: some like snug, others like relaxed. A calculator can't sense preference. So I usually use them as a compass rather than a map. I take measurements carefully, check brand-specific guides, read reviews, and if possible order multiple sizes or buy from stores with friendly return policies. For anything truly personal, trying on or precise measuring techniques (and sometimes a tailor) beats blind trust in a calculator. Still, they save me time and embarrassment when shopping online, so I lean on them — cautiously optimistic.

Let me put it this way: any online 'genital size calculator' that promises a precise adult measurement should be treated like a party trick rather than a medical device. There are a lot of those tools that ask for height, weight, shoe size, finger length or even ancestry and then spit out a number — they often rely on weak correlations or tiny datasets, and human anatomy is just too variable for a neat formula to capture it reliably. If you actually want an accurate measurement, technique matters far more than a calculator. Clinically, length is measured from the pubic bone (pressing the ruler into the fat pad) to the tip of the penis, and girth is measured at the mid-shaft with a flexible tape. Erect vs flaccid vs stretched measurements differ a lot, and factors like temperature, arousal, recent activity and how hard you press the pubic fat change the result. So even two careful measurements by the same person can differ by a centimeter or more. In short: calculators that infer size from other body parts are low-accuracy and prone to bias. If you’re curious for personal reasons, measure consistently using the standard method and expect a margin of error. If there are health or functional concerns, a clinic visit will give the most reliable assessment — and honestly, being comfortable with your body matters more than chasing a decimal point.
