براغي رأس مقبس 5/8-18 × 1-1/4 بوصة | محرك مقبس سداسي | صنع في الولايات المتحدة | فولاذ سبائكي مع أكسيد أسود حراري (325 / عبوة)

I’ve been using these in a jig I’m building, and the hex socket drive makes torquing them down really easy without slipping. The USA made alloy steel feels sturdy, and the black oxide finish hasn’t shown any wear after a few adjustments.

I needed a bulk supply of 5/8-18 screws for jig building, and these fit the bill perfectly. The hex socket drive makes it easy to torque them down with a standard Allen key, and the black oxide finish seems durable so far.

The black oxide finish on these gives them a nice uniform look, and they’re exactly the right spec for my jig builds—no fiddling with tolerance. Threads cut cleanly into the alloy steel, and a full box of 325 means I won’t be reordering for a while.
