Value Collection WY_09170341 M7 Flat Washer 18-8 Ss

Product Description

The VALUE COLLECTION WY_09170341 is an M7 standard flat washer machined from 18-8 stainless steel with a plain finish. Flat washers distribute clamp load across a fastened joint, protect mating surfaces from damage, and reduce the risk of loosening under vibration. This washer measures 7.4mm inside diameter, 14mm outside diameter, and 1.6mm thick, making it a direct metric fit for M7 fastener assemblies. Hardness is rated at 140 HV, providing solid resistance to deformation under load. Plumbers, pipefitters, electricians, HVAC technicians, and general maintenance mechanics commonly use stainless flat washers where corrosion resistance is a priority.

This washer is suited for both residential and light commercial applications where a metric M7 fastener is used and corrosion resistance is required. Typical install scenarios include equipment mounting, pipe flange assemblies, panel fastening, and any bolted joint exposed to moisture or mild chemicals. The 18-8 stainless alloy performs well in wet, outdoor, and lightly corrosive environments. Minimum order quantity is 100 pieces per order. Each package contains 1 washer.

Key Features

• Plain finish with no coating — compatible with conductive assemblies and unpainted hardware
• Meets DIN 125, ISO 7089, and ISO 7090 fastener standards
• Metric sizing: 7.4mm ID, 14mm OD, 1.6mm thickness for precise M7 fastener fit

Compatibility

Designed as a standard metric flat washer for use with M7 screws and bolts in assemblies conforming to DIN 125, ISO 7089, and ISO 7090 specifications.

Installation Notes

Install by a qualified mechanic, technician, or tradesperson following the applicable fastener torque specifications for the assembly. Ensure mating surfaces are clean and free of debris before seating the washer. Do not mix stainless steel fastener components with dissimilar metals in highly corrosive environments without evaluating galvanic compatibility. Minimum order quantity is 100 units — confirm required quantity before ordering.
