1/2-13 X 2" 六角頭螺絲 | 美國製造 | L9合金鋼黃鋅 | 部分螺紋 (50 / 包)

Needed to replace some worn bolts on a press, and these L9s threaded in perfectly with no wobble. The yellow zinc finish looks solid and the hex heads grabbed cleanly with a socket.

Put these on a heavy-duty mower deck after the old bolts stripped out, and the L9 alloy steel held tight without any issues. The partially threaded design made alignment a lot easier than I expected for a 1/2" bolt.

Drove out to the shop today and these yellow zinc heads seated real clean with a socket, the L9 alloy feels rock solid for the torque I put on them. Only gripe is I wish they came in a bigger pack, but for 50 this batch handled the job fine.
