M6 X 40mm 平端內六角止付螺絲 | 合金鋼 (250 / 包)

The flat point on these M6 screws seats firmly without wandering, and the hex socket drive takes an Allen key cleanly for a solid grip. All 250 arrived in good shape, no bent threads. Solid buy for panel adjustments.

Had a hard time getting the hex wrench to grip in a dimple I drilled, but once I switched to a better bit these M6 screws cinched down perfectly—the 40mm length gave me just enough bite in the bracket.

Used a few of these to mount some shelving brackets into metal studs, and the hex socket drive made it easy to get them snug even in tight spots. The flat point tip also helped start them cleanly without wandering. These feel plenty sturdy for hanging heavier loads.
