براغي رأس مقبس 3/4-10 × 3/4" | رأس زرية بمحرك مقبس سداسي | سبيكة فولاذية بأكسيد حراري أسود (25 / عبوة)

The thermal black oxide finish on these is spot on—uniform and slick, no rough edges anywhere. Used them to bolt down a precision fixture plate and the hex socket drive seated perfectly without stripping. Solid lot of 25 for the price.

Installed these in a jig for a repeat drilling operation and the hex socket drive made tightening easy even in tight spots. The black oxide finish looks great and seems like it'll resist rust well. Solid package of 25 for the price.

The black oxide finish on these screws gives them a nice uniform look that holds up well against minor scuffs during assembly. I've been using them for a jig fixture and the hex socket drive grabs cleanly without stripping, even at higher torque settings.
