Value Collection MP43989 M20 Flat Washer Steel Zinc-plated

Product Description

The VALUE COLLECTION MP43989 is an M20 standard flat washer manufactured from steel with a zinc-plated finish, conforming to DIN 125 fastener standard. It features a 22 mm inside diameter, 39 mm outside diameter, and 3 mm thickness, making it a reliable metric hardware component for distributing load across bolted assemblies. The zinc-plated coating provides basic corrosion resistance in general-purpose applications. This washer is suited for use in mechanical assemblies, structural connections, and equipment fabrication where M20 fasteners are specified. Tradespeople, millwrights, pipefitters, and maintenance technicians commonly reach for this part when assembling flanges, brackets, or structural frames with M20 bolts or screws.

This flat washer is intended for metric fastener assemblies requiring M20 screw compatibility. It is appropriate for both light industrial and commercial applications where a DIN 125-compliant washer is called for. Typical use cases include mounting equipment to steel frames, securing pipe hangers, and general bolted connections in mechanical rooms, plant floors, and construction settings. The steel construction and zinc-plated finish make it suitable for indoor and low-exposure environments where moderate corrosion resistance is acceptable.

Key Features

• M20 screw size compatibility with 22 mm inside diameter for proper fastener fit
• 39 mm outside diameter provides effective load distribution across mating surfaces
• 3 mm thickness meets DIN 125 dimensional standard for metric flat washers
• Steel construction with zinc-plated finish for durability and basic corrosion resistance
• Metric system measurement — consistent with DIN 125 fastener standard

Compatibility

Designed as a DIN 125-compliant standard flat washer for use with M20 metric bolts and screws in general mechanical and structural assemblies.

Installation Notes

Installation is performed by qualified tradespeople or maintenance technicians as part of bolted assembly work. Always ensure the correct washer is matched to the fastener size and material grade before assembly. Follow applicable torque specifications provided by the equipment manufacturer or relevant mechanical standards for M20 fasteners. Inspect washers for deformation or coating damage before use and replace any that show signs of corrosion or cracking.
