براغي رأس مقبس M5 × 20 مم | محرك مقبس سداسي | فولاذ سبائك (800 / عبوة)

Ordered a box of 800 for a batch of jig fixtures and every single one threaded cleanly into the tapped holes without any galling. The alloy steel feels noticeably denser than the cheap zinc-plated ones I used to pick up, and the hex socket grip is snug enough that I didn't strip a single head even a

The hex socket drive seated perfectly on my Allen key, no stripping even when I torqued them down in a tight spot. 800 pieces means I’ve got plenty for the rest of the project, and the alloy steel feels solid, not brittle.

Installed these in a jig yesterday and the hex drive seated perfectly without any stripping. The 800-count box will last my shop for months of builds.
