7/8-9 X 2-3/4" 重型六角帽螺絲 | ASTM A193 B7 合金鋼素色 (60/包)

I needed a heavy-duty bolt for a press repair, and these B7 alloy hex screws handled the torque without any deformation. The plain finish was clean and uniform across all 60 pieces, which saved me time sorting.

The threads cut perfectly into my steel plate without any binding, and the heavy hex heads gave my wrench a solid grip during tightening. These are exactly the kind of sturdy, reliable bolts I need for heavy machinery assembly.

Had a tough time finding B7s this size locally, but these threaded in cleanly on my press frame rebuild. The 60-count package saved me a return trip to the supplier.
