براغي رأس سداسية 7/16-14 × 4 بوصة | درجة 5 فولاذ صفراء زنك | خيط جزئي (200 / عبوة)

The partial threading on these made alignment a breeze when I was bolting a gearbox to its mount—no more fighting the threads through the whole shank. They’re sturdy enough that I torqued them down without a second thought, and the yellow zinc finish still looks clean after a week of oily shop use.

These bolts are solid, the grade 5 steel feels properly hardened and the yellow zinc finish gives them a clean, uniform look. Installed a batch on a jig table and the hex heads grabbed a socket perfectly without any stripping.

These bolts are perfectly adequate for heavier equipment assembly work, and the partial threading gave just enough grip for my application. The yellow zinc finish seems durable enough so far, though I wish the pack came with a few extras for the price.
