براغي رأس كبس 1/2-13 × 6 بوصة | محرك سداسي | صناعة أمريكية | فولاذ سبائكي أسود حراري (150/عبوة)

Needed some replacement screws for a worn clamping fixture, and these black oxide ones slide in smoothly with no binding. The hex socket drive engages cleanly without stripping.

For a heavy-duty jig I’m building, these socket cap screws threaded in smoothly and the hex drive gripped perfectly without stripping. The 6-inch length was exactly what I needed to reach through my assembly. Really solid feel from the alloy steel.

I’ve been buying USA-made socket cap screws for years, and the hex socket drive on these 1/2-13 x 6" ones fits my Allen wrenches perfectly without any slop. The 150-piece package is great for stocking up for custom tooling and jigs. Exactly what I needed.
