براغي رأس سداسي 5/16-18 × 1-3/8" | فولاذ درجة 8 مطلي بالزنك الأصفر | ملولبة جزئياً (1000/عبوة)

The hex heads grab a socket cleanly every time, and the yellow zinc finish has held up through a full week of assembly work without a speck of rust. Threads are crisp right up to the partial section, so they drive in straight and seat tight.

Came out to about $2 per screw, but the Grade 8 strength and yellow zinc coating are exactly what I needed for a heavy equipment repair. The partial threads made seating them in a blind hole much easier than expected.

The yellow zinc finish on these Grade 8 bolts looks really clean and should resist rust well in my garage. The partial threading made them easy to start by hand before tightening with a socket. A full thousand-count box means I won't run out mid-project.
