3/4-10 x 2-1/4" 重型六角頭螺絲 | ASTM A193 B7 合金鋼 無處理 | 全螺紋 (95 / 包)

Threads are clean and cut true to size, which saved me a headache when mounting a pump bracket last week. The alloy steel finish feels dense and sturdy, though I did need a breaker bar to torque them properly. Solid choice for any rig that sees real vibration.

These are solid for heavy equipment assembly; the knurled shank under the hex head really helps them grab and hold torque. I used them to rebuild a press frame and every one threaded in smoothly without binding.

The threading is clean and consistent on every single screw, and the heavy hex heads gave my wrench a solid bite. These feel noticeably tougher than the standard grade 5 bolts I usually grab for heavy equipment repairs.
