براغي رأس سداسي 3/8-16 × 1-1/4" | صنع في الولايات المتحدة | فولاذ سبيكة PFC9 زنك أصفر (100/عبوة)

I needed these for a small machinery project and the hex heads drove perfectly with a socket. The PFC9 alloy feels sturdy and the yellow zinc gives them a nice look.

Threads are clean and the yellow zinc finish took a wrenching without a single strip. I've used cheaper bolts before that gall, but these drove in smooth and held tight on the assembly jig. Good to have a full hundred for the next job.

These have been holding up perfectly on the assembly jig I'm rebuilding; the hex head takes a socket wrench without any stripping, and the yellow zinc coating looks like it will resist rust well. Really solid quality for the price, and the threads cut cleanly into the steel plate.
