M8 x 20mm x 1.25mm 法蘭六角螺栓

The 1.25mm thread pitch matched my existing hardware perfectly, so I didn't have to hunt for a die. My bracket is finally secure after the old bolts stripped out.

Was a bit fiddly to line up at first with the 20mm length, but once it seated it sat flush and held tight. The hex head made it easy to torque down with a socket, which I appreciated.

Threaded right into the existing bracket holes with zero fuss, and the flange head sat flush so I didn't need a washer. The 1.25mm pitch matched perfectly on the first try, which saved me a second trip to the hardware store.
