براغي رأس سداسي 5/16-18 × 1/2 بوصة | فولاذ درجة 5 أصفر زنك | كامل الخيط (300 / عبوة)

I needed a bunch of these for a jig I was building, and the yellow zinc finish on the Grade 5 steel is holding up great against rust so far. Each screw is fully threaded, which made getting a tight grip in thin metal much easier than partial-thread bolts.

The hex head on these cap screws fits my socket perfectly, and the yellow zinc coating looks clean and durable. I used a full pack on a machinery assembly and every thread was consistent. Great value for the quantity you get.

These bolts fit perfectly in my jig setup, and the yellow zinc coating gives them a nice clean look. The fully threaded shaft made it easy to clamp down on various material thicknesses, and being grade 5 steel I feel good about the strength for light machinery work.
