براغي مقبس نقطة كوب M8 × 12 مم | فولاذ سبيكة (100 / عبوة)

Used a dozen of these to secure a pulley on a small shaft assembly and the socket drive made installation quick with a hex key. The alloy steel feels sturdy and the cup point design held firm under moderate load.

Installed these on a conveyor drive pulley and the cup point held firm even under heavy load. The alloy steel feels tough, and the hex socket engaged cleanly without stripping.

The cup point really digs in—I used a dozen to lock a pulley to a shaft and they haven't budged after a week of running. Alloy steel feels plenty sturdy for the price, and the socket drive made them easy to torque down with an Allen key.
