براغي تثبيت برأس مقبس مدبب 3/8-24 × 1-1/4" | فولاذ سبيكة (100 / عبوة)

The hex socket drive made installation in a tight engine bay much easier than I expected. These alloy steel set screws feel solid and the cone point grabs the shaft securely. Got a full 100-pack for future projects, which is a nice bonus.

The cone point on these screws bites nicely into the shaft without walking, and the alloy steel feels tough enough for repeated adjustments. Exactly what I needed for securing a collar in a tight spot.

Thought I'd have a hard time getting these seated in tight spots on the mill, but the hex socket drive made them a breeze to torque down. The cone points bite cleanly into the shaft, and the alloy steel feels solid—no stripping after a full day of use.
