Gibraltar 23060.0016 M16 Flat Washer Steel Black Phosphate

Product Description

The GIBRALTAR 23060.0016 is a standard flat washer designed for M16 fastener assemblies in heavy-duty mechanical and structural applications. Manufactured from steel with a black phosphate finish, this washer distributes clamp load evenly across the bearing surface, reducing the risk of fastener pull-through and surface damage. It measures 17mm inside diameter, 45mm outside diameter, and 6mm thick. The black phosphate coating provides a base-level corrosion resistance and improves lubrication retention during assembly. This washer conforms to DIN 6340, a standard commonly specified in industrial and trade-grade fastener applications.

This washer is suited for use in industrial equipment assembly, structural steel connections, heavy machinery, and mechanical component mounting where an M16 bolt or screw is specified. The DIN 6340 standard makes it a common choice in metric fastener systems found in manufacturing, maintenance, and fabrication environments. Licensed tradespeople and maintenance technicians working on equipment requiring metric hardware will find this washer appropriate for standard load-distribution needs.

Installation Notes

Installation is performed by mechanical tradespeople, millwrights, or maintenance technicians working with metric fastener systems. Always confirm washer inside diameter matches the fastener shank diameter before installation. Use appropriate torque tools to avoid over-compression of the washer under the fastener head. Inspect the mating surface for burrs or contamination that could affect clamp load distribution.
