Shumee Mushroom Head Bolt with Serrated Flange Nut M10x20, 100 Pieces

The Shumee Mushroom Head Bolt with Serrated Flange Nut M10x20 set provides a reliable fastening solution for a wide range of assembly tasks. This set includes 100 pieces of high-quality bolts and matching nuts, designed to ensure a secure and durable connection. The mushroom head design offers a clean, low-profile finish, while the serrated flange on the nut acts as a locking mechanism to maintain tension and prevent loosening due to vibration.

Advantages

The primary benefit of this fastener set is the integrated serrated flange, which eliminates the need for additional washers and provides superior resistance against loosening in dynamic environments. The mushroom head provides a smooth, aesthetically pleasing surface that minimizes snagging risks, making it ideal for visible applications. With 100 pieces included, this set offers excellent value for both professional contractors and home DIY enthusiasts who require consistent, high-strength hardware for their projects.

Suitable for

• Automotive assembly and repair
• Construction and structural framing
• Furniture assembly and DIY projects
• General machinery maintenance
• Applications requiring vibration resistance

This product may not be suitable for high-precision engineering applications where specific torque tolerances or specialized material grades are required. It is also not intended for use in highly corrosive environments unless additional protective coatings are applied.

Key specifications

• Bolt type: Mushroom head
• Nut type: Serrated flange nut
• Thread size: M10
• Length: 20 mm
• Quantity: 100 pieces

To use these fasteners, align the components you wish to join and insert the mushroom head bolt through the pre-drilled holes. Place the serrated flange nut onto the threaded end and tighten using a standard wrench or socket. The serrations on the flange will grip the surface of the material as you tighten, creating a secure lock that resists loosening.

What to consider before purchase

• Verify that the M10 thread size is compatible with your existing holes or equipment.
• Ensure the 20 mm length is sufficient for the thickness of the materials being joined.
• Check if the material surface can withstand the pressure of the serrated flange without damage.

For optimal performance, ensure the mating surfaces are clean and free of debris before tightening. Do not over-torque the nuts, as this may damage the serrations or the surface of the material.
