M3 Black 304 Stainless Steel Flange Nut (Pack of 10)

M3 flange nuts in black-finished 304 stainless steel, sold as a pack of 10. The built-in washer flange spreads clamping force over a wider area than a plain hex nut, which helps on carbon-fibre plates, 3D-printed mounts and thin brackets that a small nut could crush or dig into.

Key features

• M3 metric thread for frame plates, stack standoffs and accessory mounts
• Integrated flange replaces a separate washer, so there is one less loose part to drop during a field repair
• Black finish blends in on carbon-fibre frames

Pick flange nuts where the nut bears directly on a soft or thin surface. They have no locking insert, so use threadlocker, or a nylon lock nut, on joints that see constant vibration.
