60PCS 3/16″ Fender Washers, 304 Stainless Steel
Material and size: 304 stainless steel, 0.047 inches thick; packaged as 60 pieces with 3/16″ inner diameter and 1″ outer diameter. Meets ASME/ANSI B18.22.1 standards. Best for: projects that demand corrosion resistance and longer life in outdoor or humid environments. Limitation: higher cost relative to basic steel washers.
3/16″ x 1″ Fender Washer (100 Pack) Zinc Plated
Material and size: Zinc plated steel with 1″ outer diameter and 3/16″ inner diameter; 100 washers per bag. Best for: industrial and commercial grade fastening where cost efficiency matters. Limitation: zinc plating may show wear over time in aggressive environments.
80PCS 3/16″ x1″ Fender Washers, 304 Stainless Steel
Material and size: 304 stainless steel, 0.047″ thick; 80 washers with 3/16″ ID and 1″ OD. Best for: users needing a robust stainless option with greater corrosion resistance and a larger bearing surface. Better for outdoor or high-humidity settings; may be pricier than basic zinc washers. Limitation: stainless steel can be harder to drive in very soft base materials.
Yaocom 200 Pcs 3/16″ x 1″ Fender Washers
Material and size: Zinc plated carbon steel; outer diameter 25mm, inner 5mm, thickness 2mm. Best for: large quantity projects requiring a balance of cost and reliability for indoor or outdoor fastening. Limitation: zinc plating offers moderate corrosion resistance, not as strong as stainless steel in salt-rich environments.
(600) Oversized #10 Fender Washers 3/16 x 1 OD
Material and size: Zinc plated; oversized 3/16″ inner diameter with 1″ outer diameter. Best for: mass-provisioned projects where a broader contact area improves load distribution. Limitation: zinc plating may wear faster in aggressive environments; consider stainless options for outdoor applications with exposure to salt or moisture.
Buying Guide: Key Considerations for 3/16 x 1 Fender Washers
- Material and corrosion resistance: Choose stainless steel for outdoor or humid environments; zinc-plated steel offers budget-friendly performance for indoor use.
- Surface area and load distribution: The 1″ outer diameter increases the bearing surface to prevent pull-through, especially on softer base materials like wood or thin metal.
- Thickness and strength: A typical thickness around 0.047 inches balances strength with flush installation. Heavier loads may benefit from thicker options if available.
- Quantity needs: For large projects, buying in bulk (200–600 pieces) reduces replacement runs and ensures substitution consistency.
- Compatibility: Confirm the screw or bolt size (commonly #10 or 3/16″ diameters) to ensure a proper fit without loosening over time.
- Environmental considerations: For coastal or salted environments, stainless steel reduces corrosion risk compared with zinc-plated alternatives.
Frequently Asked Questions
- What is a Fender washer used for? Answer: Fender washers distribute load over a wider area to prevent pull-through of fasteners into soft or thin base materials.
- What does 3/16″ x 1″ mean for these washers? Answer: 3/16″ refers to the inner diameter, and 1″ refers to the outer diameter. Thickness varies by product but is typically around 0.047 inches.
- When should I choose stainless steel over zinc-plated washers? Answer: Choose stainless steel for outdoor, high-humidity, or corrosive environments; zinc-plated is suitable for indoor or less corrosive applications.
- Are these washers compatible with #10 screws? Answer: Many 3/16″ ID washers are designed to fit #10 screws or bolts, but always verify the product specifications for exact compatibility.
- Do larger outer diameters provide better load distribution? Answer: Yes, a larger outer diameter increases the bearing surface and helps prevent pull-through in softer materials.
- How many washers should I buy for a project? Answer: Consider the number of fasteners used, expected loss, and replacement needs; bulk packs (200–600 pieces) are cost-effective for large projects.
