3/4-10 x 4" 重型六角頭螺絲 | 美國製造 | A307 B級鋼無鍍層 | 部分螺紋 (35入/包)

I needed a heavy-duty fastener for a shop press build, and these hex heads seated perfectly with a socket wrench. The 4-inch length gave me enough grip without bottoming out, and the steel feels solid.

The partially threaded length on these 3/4-10 x 4" bolts gave me just the right grip for a heavy equipment frame, and the A307 grade B steel feels solidly machined. Thread engagement was clean right out of the package, no galling or burrs. For the price per pack, these are a no-brainer for industria

Put these on a tractor hitch project where I needed that partial thread to get a solid clamp. The threads are clean and the hex heads let me torque them down without slipping. They feel heavier and more solid than the imported bolts I used last time.
