## Summary description

Mushroom-head screw with serrated nut Baks model 655061 (GKM) in M6×16 size, silver finish, supplied as a pack of 100. Designed for fastening components where a low-profile rounded head and anti-loosening serrated nut are required. Suitable for general mechanical assembly, sheet metal work and furniture fittings where vibration resistance and a neat visible head are important.

## Long description

Mushroom-head screw with serrated nut Baks GKM M6×16 in silver, supplied as a pack of 100, is a fastening solution that combines a low-profile rounded head with a serrated nut to resist loosening. The design provides a neat visible head on assembled products and the serrated nut increases friction against the mating surface, helping to maintain clamp load under vibration. This set is intended for applications where a smooth exterior appearance and reliable mechanical retention are required.
Advantages
The mushroom-shaped head offers a smooth, finished appearance and distributes load over a larger surface compared with standard countersunk or hex-head screws. The serrated nut provides integrated locking action by biting into the contact surface, reducing the risk of self-loosening in vibrating environments. Supplied as a pack of 100, the set is convenient for production runs, repair work or stock replenishment and the silver finish gives basic corrosion resistance and consistent aesthetics across visible assemblies.
Suitable for
General mechanical assembly where a visible, rounded head is preferred
Sheet metal fastening requiring vibration resistance
Furniture fittings and fixtures with exposed fasteners
Small production batches and maintenance tasks needing multiple identical fasteners
Key specifications
Screw head: mushroom (rounded) head for a low-profile visible finish
Thread size and length: M6 × 16 mm suitable for medium-thickness joints
Locking element: serrated nut providing anti-loosening action through friction
Finish: silver coating for uniform appearance and basic protection against corrosion
Package quantity: 100 pieces per pack for bulk usage
How to use
Select the screw and serrated nut pair, align the components to be joined, and insert the screw through the mating parts. Hand-start the serrated nut onto the screw and tighten using the appropriate wrench or socket while ensuring the mushroom head sits flush against the visible surface. Apply torque suitable for M6 fasteners and the materials in use; avoid over-tightening to prevent thread stripping or surface deformation. For assemblies subject to frequent disassembly, inspect the serrated nut for wear and replace if locking performance diminishes.
Usage recommendations
For optimal anti-loosening performance, tighten to the recommended torque for M6 machine screws in the specific material thickness, and ensure the contact surface under the serrations is clean and free of lubricants. Use matching thread engagement and, when joining thin sheet metal, consider backing plates or washers to distribute load and prevent pull-through.
