7/16-20 X 1-1/8" 육각 머리 캡 나사 | 미국 제조 | 8등급 강철 황색 아연 도금 | 전체 나사산 (100 / 패키지)

The yellow zinc finish on these looks even better in person, and they’re fully threaded so I didn’t have to cut anything down for a tight fit on my equipment frame. All 100 came out of the box with no burrs or damaged threads, and the hex heads seated cleanly with a standard socket.

The threading on these is clean and consistent across all 100 pieces, so they thread into nuts without any binding. The yellow zinc finish looks uniform and the hex heads are sharp enough for a socket to grip firmly. Solid choice for heavy equipment work.

Needed a handful of these for a tractor hitch repair and the 7/16-20 thread cut smooth on the first try. The hex head held a socket without slipping. Solid fasteners for the price.
