六角頭螺絲 3/8-24 x 1-1/2" | 美國製造 | Grade L9合金鋼黃鋅 | 部分螺紋 (100個/包)

The hex heads fit my socket perfectly, and the grade L9 alloy steel is noticeably tougher than standard bolts I've used before. These feel like they'll hold up well on my press jig without stripping.

The hex heads fit my 3/8" socket perfectly, and the yellow zinc finish has been holding up great with no rust after a few weeks of use. The partially threaded design made alignment in my equipment frame much easier than dealing with fully threaded bolts, and all 100 came clean and uniform.

Threads are clean and the yellow zinc coating looks consistent across all 100 bolts. The L9 alloy steel feels solid when torquing down, though I wish they'd included a bit more thread length on the partially-threaded section for my application.
