M5 x 40mm 機械螺絲 | 平頭十字驅動 | 18/8不鏽鋼 (200個/包)

The flat heads sit perfectly flush in the aluminum panel I used them on, and the stainless steel feels solid. No stripped threads or bent heads after tightening a bunch of them down. Exactly what I needed for my enclosure project.

Needed a batch of 40mm M5s for mounting some electronics enclosures and these flat heads sit perfectly flush. The 18/8 stainless finish looks clean and feels sturdy, no burrs on the threads.

Finally, a pack of M5 screws that actually fits standard enclosures without stripping the head mid-drive. The 40mm length is spot on for my panel mounts, and the flat head sits flush enough that I didn't have to countersink anything. Even the phillips slots held up through all two hundred.
