براغي تثبيت برأس مخروطي مقاس 1/2-13 × 1-1/4 بوصة | فولاذ سبائكي (100 / عبوة)

The cone point seated into the shaft’s center divot without any walking, and the alloy steel held up to some serious wrenching. I’ve used cheaper sets that stripped on the second use, but these kept their bite.

The hex socket drive gripped perfectly even in a cramped spot where I couldn't get a wrench anywhere near the bolt. All 100 screws came clean, threads intact, and the cone points seated exactly as they should. Bought these for a jig I'm building and they've held up through constant adjustments.

The cone point on these set screws bites into the shaft perfectly, and the alloy steel feels tough enough for repeated adjustments. I needed a full pack of this exact size for a project, and the price was fair for the quantity.
