3/8-16 × 3" براغي تثبيت ذات رأس مخروطي من فولاذ السبائك (50/عبوة)

The hex socket drive made it easy to snug these into my workbench jig without stripping the head, even in a cramped corner. The cone point threaded in smoothly right from the start.

I needed a long set screw for a jig I was building, and these 3-inch cone points threaded in smoothly without binding. The alloy steel feels plenty tough for repeated adjustments in tight spots.

The hex socket drive grabbed firmly without any cam-out, even when I torqued it down in a cramped spot behind the workbench. Cone point tip sank right into the wood, made alignment a breeze. Exactly what I needed for a solid, flush fit.
