براغي رأس سداسي مقاس 3/8-16 × 1-5/8 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | خيط جزئي (100/عبوة)

Threads were clean and sharp out of the box, and the yellow zinc finish looks better than the plain steel ones I’ve used before. The partial threading grabbed perfectly when I bolted down a heavy equipment guard. Pack of 100 will last me a long time.

Used these to secure a mounting bracket on a heavy-duty assembly table and the partially threaded shaft made alignment a breeze. The hex head held up perfectly under high torque with a socket wrench.

Bought these for a DIY project and was impressed by the solid feel of the Grade 5 steel and the yellow zinc finish holding up well. The partially threaded design made tightening a breeze with my socket.
