Flange Nuts

This M3 flange nut is a compact yet highly effective fastening solution designed to simplify mechanical and electronic assemblies. Featuring a wide flange base with a textured, uneven surface, this hardware component provides a firm grip directly against the mounting surface — securing circuit boards, sensors, and structural components without the need for additional washers. Ten nuts are included per package, making this a practical and ready-to-use addition to any maker's toolkit.

Wide Flange Design Eliminates Extra Washers

This M3 flange nut integrates a broad, flat flange at one end that distributes clamping force across a wider surface area. The uneven texture on the flange face increases friction against the mounting surface, preventing the nut from loosening under vibration or repeated use. This built-in washer-like feature reduces parts count, simplifies assembly, and lowers the risk of hardware shifts during operation — a meaningful advantage in compact builds where space and reliability both matter.

Versatile Mounting for Electronics and Mechanics

This M3 flange nut is well suited for securing circuit boards, sensors, and mechanical structural elements in robotics, embedded systems, and prototyping platforms. The standard M3 thread ensures broad compatibility with commonly available M3 bolts and standoffs. Whether used in lightweight sensor brackets or more robust chassis assemblies, this fastener delivers consistent clamping performance across a wide range of maker and engineering applications.

From robotics frames and electronics enclosures to sensor brackets and prototype platforms, this M3 flange nut is a dependable fastening choice wherever reliable, washer-free hardware mounting is required. The included pack of ten provides enough quantity for multi-point assemblies, making project builds faster, cleaner, and more secure.
