مسامير آلية سداسية مقاس 5/16-24 × 2 بوصة | فولاذ مطلي بالزنك | ملولبة جزئيًا (50/عبوة)

The partially threaded shank is perfect for when I need a solid grip against the frame before the threads bite. All fifty bolts came out of the bag uniformly coated, no rust or burrs on any of them.

The zinc plating on these bolts gives them a nice, consistent finish that resists rust well. I needed a precise unthreaded grip length for a jig I was building, and the partially threaded shank worked perfectly for that. They threaded into my tapped holes smoothly without any binding.

The unthreaded grip section sits flush in the clearance hole, which made aligning the bracket much easier than with fully threaded bolts. Zinc coating looks uniform and no rust after a few humid days. Only wish the threads were a touch longer for thicker nuts.
