Gibraltar 23060.0012 M12 Standard Flat Washer Steel Din 6340

Product Description

The GIBRALTAR 23060.0012 is a metric standard flat washer designed to distribute clamping load under bolt heads and nuts in structural and mechanical assemblies. Manufactured from steel with a black phosphate finish, this washer meets DIN 6340 fastener standards and is sized for M12 screws. The 13mm inside diameter, 35mm outside diameter, and 5mm thickness make it a heavier-duty flat washer suited for applications requiring a wider load-bearing surface. It is installed by mechanics, millwrights, and maintenance technicians across general industrial, construction, and equipment assembly work.

This washer is appropriate for use in metric fastener assemblies where DIN 6340 compliance is specified. The black phosphate finish provides a degree of corrosion resistance and reduces surface reflectivity, making it common in industrial equipment, structural steel connections, and machinery mounting applications. It is sold individually but carries a minimum order quantity of 5 units per transaction.

Key Features

• Meets DIN 6340 standard for metric flat washers
• Steel construction for durability under load
• Black phosphate finish for mild corrosion resistance and a non-reflective surface
• 13mm inside diameter for M12 screw fitment
• 35mm outside diameter provides wide load distribution
• 5mm thickness for added strength in heavy-duty assemblies

Compatibility

Designed for use with M12 metric fasteners in assemblies requiring DIN 6340 standard flat washers.

Installation Notes

Install using standard hand tools appropriate for M12 fastener assemblies. Ensure mating surfaces are clean and free of debris before seating the washer. Follow applicable torque specifications for the M12 bolt or nut being used as defined by the equipment manufacturer or relevant mechanical standards. Do not substitute this washer in applications requiring a different DIN or ISO washer standard without verifying dimensional and load compatibility.
