براغي رأس سداسي 5/16-24 × 2 بوصة | صناعة أمريكية | درجة L9 سبيكة فولاذية مطلي بالزنك الأصفر | خيط جزئي (100/عبوة)

The partially threaded design made aligning them in tight spots a breeze, and the L9 alloy steel feels incredibly tough. These hex heads grabbed perfectly with a socket on my press jig rebuild.

Used these to secure a new motor mount on my lathe and the partially threaded design made alignment much easier. The hex heads grabbed cleanly with a socket, no stripping at all.

The yellow zinc coating is holding up great on the assembly line, no scratches after a week of heavy wrench use. These Grade L9 hex heads torque down solid and the partial threading gives just the right bite for our equipment frames.
