7/8-9 X 4인치 육각 머리 캡 나사 | 미국 제조 | L9 합금강 황색 아연 도금 | 부분 나사산 (15 / 팩)

Needed these for a heavy press repair and the yellow zinc coating on the Grade L9 heads is holding up great against the wrench. The partial thread made it easy to get the right grip depth without bottoming out.

Threaded perfectly into our hydraulic press frame without any binding, and the L9 alloy steel feels seriously stout for the torque we're putting on them. The hex heads seated cleanly with a socket, no rounding even after cranking them down hard. For the price per package, these are the ones I'll gra

The yellow zinc finish on these held up perfectly during a long day of assembly work, no galling or wear on the threads. That partially threaded design gave me just the right grip for a heavy equipment frame. Solid buy for the price, exactly what I hoped for in a US-made fastener.
