3/4-10 X 2-1/2" براغي سداسية ثقيلة | صنع في الولايات المتحدة | فولاذ A307 درجة B عادي | كاملة الخيوط (50 / عبوة)

Bought these for a gearbox rebuild and the fully threaded length let me stack a couple of heavy washers without running out of bite. The A307 steel is solid and the threads cut clean with no burrs. Two dozen used so far, zero stripped or galled.

The hex heads held up perfectly under the torque from my impact wrench without any rounding. These are solid fasteners for heavy-duty machinery assembly. Exactly the reliable grip I needed for the frame.

Used these to secure a submersible pump bracket, and the fully threaded shaft grabbed clean through the base plate. No stripping or wobbling during install. Exactly the heavy-duty fastener I needed for the job.
