Value Collection 43989 M20 Standard Flat Washer Steel Zinc-plated

Product Description

The VALUE COLLECTION 43989 is a standard flat washer designed for use with M20 metric fasteners. Made from steel with a zinc-plated finish, it provides a broad bearing surface that distributes clamping load and helps prevent fastener pull-through in bolted assemblies. The washer measures 22 millimeters inside diameter, 39 millimeters outside diameter, and 3 millimeters thick, conforming to DIN 125 specifications. The zinc plating provides basic corrosion resistance suitable for general-purpose mechanical and structural applications. This type of hardware is handled daily by millwrights, pipefitters, maintenance technicians, and general contractors working on equipment assembly and structural fastening tasks.

This flat washer is suited for residential, commercial, and light industrial bolted connections where M20 fasteners are specified. It is commonly used in structural steel connections, equipment mounting, pipe flange work, and general mechanical assembly. The DIN 125 standard ensures dimensional consistency, making this washer a reliable fit wherever a metric M20 flat washer is called out on a bill of materials or repair specification.

Key Features

• DIN 125 standard compliance ensures consistent metric dimensions across assemblies
• 22 millimeter inside diameter fits M20 metric fasteners
• 39 millimeter outside diameter distributes clamping load over a broad surface area
• 3 millimeter thickness provides solid load-bearing support without excessive stack height
• Zinc-plated steel construction offers general-purpose corrosion resistance

Compatibility

Designed as a standard DIN 125 flat washer for use with M20 metric bolts, screws, and nuts in general mechanical and structural fastening applications.

Installation Notes

Installation is performed by qualified tradespeople following applicable mechanical or structural assembly specifications. Always confirm the washer inside diameter and grade match the fastener and joint requirements before assembly. Torque fasteners to values specified in the relevant engineering or equipment documentation. Inspect washers for deformation or coating damage before reuse in critical joints.
