براغي مقبس ذات نقطة كوب مخددة 1/2-13 × 2 بوصة | فولاذ سبائكي (50/عبوة)

Set these in a fixture for a heavy jig I’m building and the knurled cup point locked down tight on the work piece without any slipping. The alloy steel feels quality, and being able to use a hex key makes adjustments in tight corners a breeze.

The hex socket drive made installation a breeze with my Allen wrench, even in that cramped spot behind the motor mount. These 2-inch set screws held firm under heavy vibration, and I like that they're alloy steel rather than cheap stainless.

The knurled cup point on these set screws really bites into the shaft and holds tight without slipping. I used them on a heavy-duty fixture and they haven’t backed out at all. Good value for a bulk pack of 50.
