مسامير رأس مقبس 3/8-16 X 3/4" | رأس مسطح سداسي | فولاذ سبائكي (100 / عبوة)

Used these to hold a fixture plate on my mill and the flat head seats perfectly flush every time. The alloy steel feels plenty tough for the torque I put on them, and all 100 came with clean threads and a consistent hex socket.

Installed a full set of these into a new jig this morning and the hex socket drive grabbed perfectly with no stripping. The alloy steel feels dense and solid, and the flat heads seated cleanly against my counterbores. Exactly what I needed for precision work.

The flat head sits flush without any wobble, and the alloy steel feels solid even under a good bit of torque. I’ve used a dozen on a jig setup so far, and every one threaded cleanly without any burrs. Just what you want from a bulk pack.
