Gibraltar 23060.0018 M18 Standard Flat Washer Steel Din 6340

Product Description

The GIBRALTAR 23060.0018 is a standard flat washer designed for use with M18 metric fasteners. Manufactured from steel with a black phosphate finish, this washer distributes clamp load evenly across the bearing surface, protecting base materials and reducing fastener loosening under vibration. It measures 19 mm inside diameter by 45 mm outside diameter and 6 mm thick, conforming to DIN 6340 dimensional standards. It weighs approximately 1 pound per unit. This washer is installed by maintenance technicians, millwrights, and mechanical contractors in industrial assembly, structural, and equipment-mounting applications.

This washer is suited for metric fastener assemblies in industrial and commercial settings where a DIN 6340 standard flat washer is required. The black phosphate finish provides a base level of corrosion resistance and lubricity, making it appropriate for general mechanical assemblies, machine building, and structural connections using M18 hardware.

Key Features

• DIN 6340 dimensional standard for consistent metric fitment
• Steel construction for reliable load distribution and clamping performance
• Black phosphate finish provides corrosion resistance and mild lubricity
• 19 mm inside diameter fits M18 fastener shanks
• 45 mm outside diameter and 6 mm thickness provide broad bearing surface

Compatibility

Designed for use with M18 metric fasteners in applications requiring a DIN 6340 standard flat washer in the metric system of measurement.

Installation Notes

Install by qualified mechanics, millwrights, or maintenance technicians as part of a metric fastener assembly. De-energize or lock out equipment before performing any fastener work on active machinery. Ensure the washer seats flush against the bearing surface before torquing the fastener. Follow applicable equipment manufacturer guidelines and relevant mechanical codes for fastener assembly procedures.
