Value Collection 09181918-100 No. 8 Flat Washer 316 Ss

Product Description

The VALUE COLLECTION 09181918-100 is a No. 8 screw standard flat washer manufactured from Grade 316 stainless steel with a plain finish. It measures 11/64 inches inside diameter, 3/8 inches outside diameter, and 0.031 inches thick. Grade 316 stainless steel provides strong corrosion resistance, making this washer suited for wet, chemical, or marine environments where standard steel fasteners would degrade. It is used by plumbers, electricians, HVAC technicians, pool service professionals, and general trade contractors when assembling or securing components with No. 8 screws in corrosive or high-moisture conditions.

This washer is appropriate for residential and light commercial applications where a No. 8 screw fastener assembly requires load distribution across a surface. Typical installation scenarios include equipment mounting panels, pipe hangers, electrical enclosures, pool equipment housings, and outdoor fixture installations. Its plain finish keeps the profile low-profile and interference-free in tight fastener clearances.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• Inside diameter of 11/64 inches fits No. 8 screws with standard clearance
• Outside diameter of 3/8 inches provides adequate load-bearing surface area
• Thickness of 0.031 inches maintains a low profile in close-tolerance assemblies
• Plain finish with no coating eliminates galvanic incompatibility concerns in all-stainless assemblies
• Inch measurement system for compatibility with standard US fastener tooling

Compatibility

Designed as a standard flat washer for use with No. 8 screws in inch-measurement fastener assemblies. Suitable for applications requiring Grade 316 stainless steel corrosion resistance.

Installation Notes

Install using standard hand tools appropriate for the fastener assembly. Ensure the mating screw and nut are also Grade 316 stainless steel where full corrosion resistance is required, as mixing fastener materials can introduce galvanic corrosion. Power down or de-energize any electrical enclosure before accessing interior fastener points. Follow applicable NEC or IPC guidelines for fastener material selection in code-governed installations.
