3/8-16 x 1" 內六角螺絲 | 六角驅動 | 美國製造 | 全螺紋 | 黃銅 (100 / 包)

I’ve been using these for a custom jig I’m building, and the brass threads cut cleanly without any binding. The hex socket is machined precisely, so my driver fits snugly every time. Definitely solid hardware for precision work.

The hex socket drive works perfectly with my standard Allen wrench, and the brass threads cut cleanly into my jig fixture without any binding. These are exactly the right length for smaller precision assemblies where you need a flush fit. Great quality for the price.

Finally found a domestically made brass screw that doesn't strip out. The hex socket drive fits my allen wrench perfectly and the threading is clean all the way down.
