3/8-16 × 3-1/2" براغي مقبس نقطة مسطحة | فولاذ سبائكي (100 / عبوة)

These fit perfectly in my machine's jam nuts and the hex drive made installation a breeze even in that awkward spot. The alloy steel feels rock solid, exactly what I needed for this repair.

I used these to secure a heavy workbench leg that kept wobbling, and the full 3-1/2" length gave me plenty of thread engagement in the steel frame. The flat point seated nicely without marring the surface, and the alloy steel feels sturdy enough for repeated adjustments.

I was worried the alloy steel might be brittle, but these screws drove smoothly into steel without snapping. The flat point tip made alignment in tight spots much easier than I expected.
