براغي رأس سداسية مخروطية 1/2-13 × 7/8" من سبائك الصلب (100/عبوة)

The hex socket drive grabbed the cone point threads perfectly when I torqued them down in a tight spot behind a motor mount. Alloy steel feels dense and machined clean, no burrs on the tips. That box of a hundred will last me a long time.

I was pleasantly surprised by how well the hex socket drive engages without stripping—even at higher torque. These cone point screws hold firm in my metal jig fixtures.

The hex socket drive made it easy to tighten these in a tight spot under my workbench, and the alloy steel feels sturdy enough for repeated use. A solid choice for this thread size.
