10mm x 40mm 육각 소켓 헤드 캡 스크류

The 10mm x 40mm cap screw fit perfectly into my old assembly, and the hex socket drove smoothly without any cam-out. It was exactly the right thread pitch for my valve cover, and the price was reasonable for a single replacement part.

I needed a replacement for a stripped bolt on my equipment, and this one matched the original’s thread pitch exactly. The hex socket drove smoothly with my Allen key, and the 40mm length was just right for the hold I needed.

Had to replace a stripped bolt on my workshop rack, and these 10x40 socket heads threaded in smooth as butter. The hex fit was snug and the black finish looks clean. Perfect match for what I needed.
