Value Collection 30776 Flat Washer 20 Screw Silicon Bronze 25pk

Product Description

The VALUE COLLECTION 30776 is a standard flat washer manufactured from silicon bronze, designed to distribute load and protect mating surfaces under fastener heads and nuts. With an inside diameter of 0.336 inches, an outside diameter of 0.75 inches, and a thickness of 0.064 inches, this washer is sized for a No. 20 screw. Silicon bronze offers excellent corrosion resistance in wet, marine, and chemically active environments, making this washer a dependable choice where carbon steel or plain zinc-plated hardware would degrade. Sold in packages of 25, these washers suit both small-batch repairs and repetitive assembly work in plumbing, marine, and general mechanical applications.

This flat washer is appropriate for residential and light commercial fastening tasks where corrosion resistance is a priority. Typical use cases include plumbing fixture mounting, marine deck hardware, pump and valve assembly, and any outdoor or high-humidity installation where galvanic compatibility with copper alloy fasteners is required. The inch-measurement sizing conforms to standard imperial washer dimensions, keeping it compatible with common imperial fastener sets found on most job sites.

Key Features

• Silicon bronze construction provides strong resistance to corrosion in wet and marine environments
• Inside diameter of 0.336 inches fits No. 20 screw shafts cleanly
• Outside diameter of 0.75 inches distributes clamping load across a broad bearing surface
• Thickness of 0.064 inches provides consistent, uniform load distribution without excessive stack height
• Package quantity of 25 supports repetitive fastening tasks and small-project restocking
• Imperial inch measurement system for direct compatibility with standard imperial fastener tooling

Compatibility

Designed as a standard flat washer for use with No. 20 imperial screws in applications requiring silicon bronze corrosion resistance.

Installation Notes

Flat washers are installed by plumbers, marine technicians, and general mechanical trades using standard hand tools. Always place the washer flush against the mating surface before seating the fastener. Do not over-torque fasteners against bronze washers, as the softer alloy can deform under excessive clamping load. Verify galvanic compatibility with adjacent metals before installation in saltwater or chemically active environments.
