براغي رأس كبس مقبس سداسي 3/8-16 × 12" | محرك سداسي | خيط جزئي | فولاذ سبائكي مع أكسيد أسود حراري (20/عبوة)

Perfectly sized for mounting heavy jigs on my mill table, and the 12-inch length saved me from stacking multiple shorter bolts. The hex socket drive made installation easy even in tight spaces, and the black oxide finish seems durable so far.

The black oxide finish on these screws looks sharp and held up well during assembly, no chips or bare spots after torquing them down in my jig fixtures. Partially threaded length is perfect for clamping thick plates without bottoming out, and the hex socket drive engaged cleanly every time.

I needed a set of partially threaded 12-inch screws for a jig I’m building, and these fit perfectly with the 3/8-16 thread pitch. The hex socket drive made tightening them quick, and the black oxide finish seems like it’ll hold up well in my shop.
