براغي تثبيت بمقبس سداسي M4 × 16mm نقطة مسطحة | فولاذ سبائكي (500 / عبوة)

The hex socket drive really saves the day when you’re torquing these down in a cramped corner—no stripped heads here. I’ve already gone through a quarter of the 500 pack on my rebuild and every single one threads cleanly.

I needed a solid set screw for a tight adjustment on my CNC jig, and the hex socket drive made it easy to torque down in a cramped spot. The flat point gripped the shaft perfectly without marring it—great for the money.

For a small screw, the alloy steel feels surprisingly solid—these flat point heads drive flush without stripping, even when I'm working in a tight cabinet hinge. Pack of 500 means I won't be reordering anytime soon.
