براغي ذات رأس أسطواني مقاس 3/4-10 × 6-1/2" | رأس مسطح مع محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي مع أسود حراري (10 / عبوة)

The flat head sits flush perfectly on my jig fixture, and the black oxide finish is holding up well to oil and chips. I've used a few packs already without a single stripped hex socket.

Fit perfectly on my mill’s T-slots and the thermal black oxide finish hasn’t shown a hint of rust after a few oily weeks. The hex socket drive seated cleanly with no stripped corners, even torqued down hard. Partial threading made alignment on the fixture plate way easier than full-threaded bolts.

I needed something heavy-duty for a jig I was building, and these screws fit the bill perfectly. The partially threaded design made alignment easier than I expected, and the black oxide finish hasn’t shown any wear after a few weeks of use.
