براغي تثبيت رأس مخروطي 3/8-24 × 1-1/2 بوصة | فولاذ سبائكي (100/عبوة)

The cone point really bites into the shaft, so these set screws hold firm even under vibration. Worked perfectly for locking a gear onto a keyless hub.

The hex socket drive made tightening these in a confined spot under my workbench a breeze. The cone point seated perfectly without stripping, and the alloy steel feels solid for the price.

I needed something that could handle repeated adjustments without stripping, and these cone point screws dig in nicely. The hex socket drive really lets you torque them down in cramped spots without the bit slipping. A solid 100-pack for the money.
