Value Collection 42464 M8 Standard Flat Washer Steel Zinc-plated

Product Description

The VALUE COLLECTION 42464 is a metric M8 standard flat washer manufactured from steel with a zinc-plated finish. It is designed to distribute load across fastener assemblies, reducing surface damage and preventing fastener pull-through. With an inside diameter of 8.4 millimeters, an outside diameter of 16 millimeters, and a thickness of 1.6 millimeters, this washer meets DIN 125, ISO 7089, and ISO 7090 dimensional standards. A hardness rating of 140 HV provides reliable performance under mechanical load. Installers in HVAC, plumbing, electrical, and general mechanical assembly applications rely on flat washers like this one for routine fastening tasks.

This washer is suited for use wherever M8 fasteners are used in metric assembly work, including equipment mounting, panel fastening, and structural bracketing in light to medium-duty commercial and residential applications. The zinc-plated finish provides a basic level of corrosion resistance for indoor and moderately protected outdoor environments. Compliance with DIN 125, ISO 7089, and ISO 7090 standards makes it a straightforward drop-in fit for metric fastener assemblies requiring standardized hardware.

Key Features

• M8 screw size with 8.4 millimeter inside diameter for standard metric bolt clearance
• 16 millimeter outside diameter distributes clamp load over a wider bearing surface
• 1.6 millimeter thickness meets DIN 125, ISO 7089, and ISO 7090 dimensional standards
• Steel construction with zinc-plated finish for basic corrosion resistance
• 140 HV hardness rating supports consistent performance under mechanical load
• Metric system of measurement for compatibility with metric fastener specifications

Compatibility

Designed as a standard metric replacement flat washer for use with M8 fasteners in assemblies conforming to DIN 125, ISO 7089, or ISO 7090 specifications.

Installation Notes

Flat washers are installed by hand between the fastener head or nut and the mating surface prior to tightening. Always power down or de-energize equipment before servicing fastened assemblies in electrical or HVAC applications. Use calibrated torque tools appropriate to the fastener grade and application; do not overtighten, as this can deform the washer and reduce clamping effectiveness. Follow applicable codes and equipment manufacturer guidelines for fastener selection and torque requirements.
