براغي تثبيت بمقبس سداسي بنقطة كوب مخددة M16 × 35 مم | فولاذ سبائكي (50 / عبوة)

The knurled cup point really bites into the shaft without stripping, and the hex socket made tightening them in a cramped spot way easier than I expected. These feel solid for the price, and the 50-pack means I've got spares for the next job.

I needed some heavy-duty set screws for a gear hub, and these M16s fit the bill perfectly. The hex socket drive made installation a breeze even in that cramped space behind the motor mount.

The knurled cup point really digs in and holds tight, even on a slightly worn shaft where other set screws just slipped. The hex socket drive made torquing them down in a cramped spot way easier than I expected. Solid pack of fifty, no stripped threads on any of them.
