(50pcs) M4 Flange Nut for 4mm Bolt, White

Overview

The M4 Flange Nut (Pack of 50 Pcs) is an essential metric fastener engineered to deliver high clamping strength and vibration resistance. Combining a standard hexagonal nut with an integrated wide circular flange base, this nut acts as a one-piece fastener and washer combination. It eliminates the need for separate flat washers, speeding up assembly time and reducing loose hardware count.

Load Distribution & Surface Protection

The wide circular flange at the bottom of the nut expands the load-bearing surface area against the joined material. This prevents the nut from digging into soft materials like aluminum, acrylic, wood, or 3D-printed plastic parts. By distributing the torque evenly, it minimizes localized stress, prevents cracking, and ensures a rigid, non-loosening joint.

Cost-Effective 50-Piece Pack

Packaged in a convenient 50-piece quantity, this set is tailored for makers, engineers, and repair technicians working on prototyping or serial assembly. The precision-cut internal threads allow fast, clean threading onto standard M4 bolts and studs without binding or galling.

Common Applications

• 3D Printers & Additive Manufacturing: Fastening extrusion corners, motor mounts, hotend carriages, and power supply brackets.

• CNC Routers & Laser Cutters: Securing gantry plates, linear rail brackets, and cable drag chains.

• Drones, Robotics & RC: Assembling lightweight carbon fiber chassis and motor mounting arms.

• Electronics & Enclosures: Fastening sheet metal panels, DIN rail clips, and heavy-duty chassis components.

Flange nut are used to spread the load evenly to avoid uneven fastening surface of the operations. They also ensure that the fasteners are in place without moving about loosely. These wide flange nuts can be used as a replacement to the nut and washer combination. Therefore, these nuts are a cost-effective and quality substitute for nuts and washers if your project is a large scale one.

Flange weld nut come in varying sizes to allow its use with several bolts, each with different dimensional standards. Another advantage of these nuts is that they prevent the loosening of machining and electrical components while still allowing the free parts to move freely. Striking the perfect balance, in this case, has to be done with careful calibrations.
