براغي رأس مقبس #8-32 × 1-1/4" | رأس مسطح بمحرك سداسي | خيط جزئي | سبيكة فولاذ بأكسيد حراري أسود (400 / عبوة)

The flat head sits perfectly flush in my jig fixtures, and the alloy steel with that black oxide finish is holding up great under repeated use. For a 400-pack at this price, the threading is consistent across the batch which saves me a ton of sorting time.

I needed a batch of strong screws for a jig project, and these alloy steel ones with thermal black oxide hold up nicely without stripping during installation. The hex socket drive made tightening in tight spots a breeze, and they're exactly the right fit for precision assembly work.

The flat head sits perfectly flush in the counterbore, which made aligning these for a jig project much easier than I expected. They’re plenty strong for light machinery work, though I wish the black oxide coating was a touch more consistent across all 400 pieces.
