Value Collection FW5S03000-005B M30 Flat Washer 5-pack

Product Description

The VALUE COLLECTION FW5S03000-005B is a metric standard flat washer designed for use with M30 fasteners. Manufactured from steel with a zinc-plated finish, this washer provides a bearing surface that distributes clamp load and protects the mating material from fastener damage. The zinc coating offers basic corrosion resistance suitable for general-purpose indoor and light-duty applications. With an inside diameter of 31mm, an outside diameter of 56mm, and a thickness of 4mm, it conforms to DIN 125, ISO 7089, and ISO 7090 fastener standards. Each package contains 5 washers.

This washer is suited for structural assembly, mechanical fabrication, and maintenance applications where M30 fasteners are used. It is commonly installed in industrial equipment, steel framing, heavy machinery mounting, and general metalwork. The DIN 125 and ISO 7089/7090 compliance makes it appropriate for metric-standard assemblies across manufacturing, construction, and maintenance environments. Electricians, millwrights, pipefitters, and general maintenance technicians working with M30 hardware will find this a standard consumable in their workflow.

Key Features

• M30 screw size with 31mm inside diameter for direct fit on M30 bolts and threaded rod
• 56mm outside diameter provides broad load distribution across mating surfaces
• 4mm thickness delivers solid bearing surface with minimal flex under clamp load
• Steel construction with 140 HV hardness rating
• Zinc-plated finish for basic corrosion resistance
• Meets DIN 125, ISO 7089, and ISO 7090 fastener standards

Compatibility

Designed for use with M30 metric fasteners in assemblies conforming to DIN 125, ISO 7089, or ISO 7090 standards.

Installation Notes

Install with standard hand tools or impact equipment appropriate for M30 fastener assemblies. Ensure the washer seats flat against the mating surface before applying torque to the fastener. Discontinue use if the washer shows signs of deformation, cracking, or corrosion that compromises the bearing surface. Follow applicable assembly standards and torque specifications provided by the fastener or equipment manufacturer.
