Gibraltar 23060.0010 M10 Standard Flat Washer Steel

Product Description

The GIBRALTAR 23060.0010 is a standard flat washer designed for M10 screw applications, manufactured from steel with a black phosphate finish. Conforming to DIN 6340 fastener standards, this washer measures 10.5mm inside diameter, 28mm outside diameter, and 4mm thick. It is used to distribute load across a fastening surface, reduce surface damage, and provide a stable bearing surface under bolt heads or nuts. Licensed tradespeople and industrial assembly technicians working in metric-hardware applications will find this washer a direct-fit, spec-compliant solution for structural and mechanical fastening jobs.

This washer is suited for mechanical assembly, structural connections, and general industrial fastening where metric hardware is specified. The black phosphate finish offers a degree of corrosion resistance and reduces light reflection in finished assemblies. It is commonly used in equipment installation, panel mounting, and machinery assembly scenarios where M10 metric fasteners are called out by spec or drawing. The DIN 6340 standard makes it appropriate for applications requiring dimensional consistency across a production or service run.

Key Features

• Conforms to DIN 6340 fastener standard for dimensional consistency
• Steel construction provides strength and durability in mechanical fastening applications
• Black phosphate finish for moderate corrosion resistance and low-reflectance surface
• 10.5mm inside diameter designed for M10 metric screws and bolts
• 28mm outside diameter distributes load across a wider bearing surface
• 4mm thickness provides solid, consistent clamping support

Compatibility

Designed for use with M10 metric screws and bolts in applications conforming to DIN 6340 specifications.

Installation Notes

Installation is performed by qualified tradespeople or mechanical assemblers using standard metric hand or power tools. Always ensure the washer is seated flat against the mating surface before torquing the fastener. Follow project drawings or applicable standards for specified fastener torque values. Inspect washers for deformation or corrosion before reuse in critical fastening applications.
