HOLO-KROME 65036 براغي رأس مقبس 3/8-24 × 1/2 بوصة | محرك سداسي رأس زر | فولاذ سبائكي مع أكسيد أسود حراري (50 / عبوة)

Threaded a few of these into a jig I’m building and the hex socket drive seated perfectly with no wobble, even at that short 1/2" length. The thermal black oxide coating gives them a clean, uniform look that’s held up fine so far. For fifty pieces at this price, they’re a solid buy for any precision

The black oxide finish on these is holding up perfectly in my jig fixtures, with no rust after several weeks of use. The hex socket drive grips cleanly, making installation quick and secure.

Was tired of stripping hex heads on cheaper bolts, but these button heads hold firm even at higher torque settings. The 3/8-24 threads cut cleanly into the jig I'm building, and the 50-count pack is perfect for stocking the shop.
