7/8-9 X 6" 육각 머리 캡 나사 | 미국산 | PFC9 합금강 황색 아연 도금 (10개/팩)

I used these to secure a heavy press at the shop and the PFC9 alloy steel feels much tougher than the last bolts I grabbed. The 6" length was exactly what I needed to get through the frame with room for a lock washer.

The yellow zinc finish is holding up great in my shop so far, and the threads cut cleanly into steel without any binding. These hex heads are a solid fit for a socket wrench, which made tightening them in tight spots a breeze.

Threads were clean and the hex heads seated perfectly in my impact socket without any wobble. The yellow zinc finish looks sharp and these PFC9 bolts are definitely not the soft import junk I've dealt with before. Solid purchase for the price.
