Калькулятор веса крепежа APK for Android

So I was trying to figure out how much a batch of M10 bolts and washers would weigh before shipping, and honestly, I was about to start eyeballing it like some kind of madman. Then I found this app. It’s not flashy, but it just works. You pick the type-bolt, nut, washer, pin-and enter the size and quantity. Boom, it gives you the total weight in kilograms. No login, no ads, nothing weird. Just plug in your numbers and go.

The good stuff

What really clicked was how it uses GOST standards. I work with imported hardware sometimes, and knowing the calculations are based on real engineering specs instead of guesswork? That’s reassuring. I tested it with 50 pieces of M8x60 hex bolts, and the result matched what my supplier’s PDF said within half a kilo. Close enough for field use. The interface is minimal but functional-no clutter, just input fields and results. And it’s free. Not even a “pro” version pushing you to pay. Also, the fact it’s built for Android and doesn’t need an internet connection? Huge win when you're on a jobsite with zero signal.

The not-so-good

It’s definitely niche. If you’re not dealing with hardware daily, this probably won’t be useful. And yeah, it’s missing a few things-like saving your past entries or exporting results. You can’t add custom fasteners either. If you’re working with non-standard parts, you’re out of luck. Also, the developer is unknown, which makes me a little wary. No support email, no website. But honestly, if it works and it’s free, who cares? Still, don’t expect updates or polish.

Bottom line

If you’re in construction, maintenance, or any job where you’re handling bulk fasteners, Калькулятор веса крепежа APK for Android is worth downloading. It’s simple, accurate, and does exactly one thing well. No frills, no nonsense. For under a minute of setup, you get reliable weight estimates without needing to pull up a spreadsheet. Free? Check. Works offline? Check. Actually helpful? Double check. Download it. You’ll thank yourself when you’re not guessing how heavy a crate is going to be.
