براغي رأس سداسي 3/8-24 × 4 بوصة | فولاذ درجة 5 مع طلاء زنك أصفر | ملولبة جزئيًا (50 / عبوة)

Used these on a tractor implement rebuild and the partially threaded section made alignment a breeze. Hex head grabbed cleanly with a socket, no stripping. Solid buy for the price.

Installed these on a motor mount and the yellow zinc finish feels really durable and corrosion resistant. The hex head fit my socket perfectly without slipping on the first three I torqued down.

The partially threaded design made these easy to start by hand before I finished tightening with a socket. I used them to replace bolts on a hydraulic press and they held up perfectly under high torque. Exactly what I needed for heavy equipment assembly.
