Technical Superiority: Zinc Fender Washers That Outperform

Our zinc-plated 3/16" thick fender washers deliver 40% better load distribution than generic models. The secret? Precision-stamped edges prevent material bite-through, while the 1.5" outer diameter creates optimal surface coverage. Need corrosion resistance? Our 5-micron zinc coating withstands 500+ hours in salt spray tests.

Fender Washer Showdown: 3/8" vs Standard

Feature	Our 3/8" Washer	Generic Washers
Load Capacity	2,800 lbs	1,200 lbs
Corrosion Resistance	ASTM B633	No Certification
OD Tolerance	±0.005"	±0.03"

Manufacturer Comparison: Why We Beat the Competition

While Acme Corp's 3/16 fender washers claim "industrial strength", ours deliver measurable results. Third-party tests show our zinc coating lasts 3x longer in marine environments. Unlike flat-faced competitors, our radial serrations increase friction by 18% – crucial for vibration-prone applications.

Custom Solutions for Unique Challenges

Need oversized 3/8 x 1-1/2 fender washers for composite materials? Our laser-cutting tech accommodates custom IDs/ODs within 72 hours. Recently helped an aerospace client create nickel-alloy washers that withstand 1,200°F – because one size doesn't fit all.

Real-World Success: Where Fender Washers Shine

Portland's GreenSky Tower used our zinc fender washers in their seismic retrofit project. Result? Zero fastener failures during 7.2 magnitude simulated quakes. As lead engineer Mark T. said: "The load distribution specs made these washers non-negotiable."

FAQS on 3 8 x 1 1 2 fender washer

Q: What is a 3/8 x 1 1/2 fender washer used for?

A: A 3/8 x 1 1/2 fender washer provides a wide bearing surface for bolts or screws. It distributes load pressure evenly, making it ideal for automotive repairs, plumbing, and machinery assembly where oversized support is needed.

Q: Why choose a zinc fender washer over standard washers?

A: Zinc fender washers offer corrosion resistance, making them perfect for outdoor or high-moisture environments. The zinc coating also adds a protective layer that extends the washer's lifespan in harsh conditions.

Q: What's the difference between a 3/16 and 3/8 fender washer?

A: The 3/16 fender washer has a smaller inner diameter (0.1875") than the 3/8" version (0.375"). This size variation determines compatibility with different bolt sizes while maintaining the characteristic wide outer diameter for surface protection.

Q: When should I use a zinc fender washer?

A: Use zinc fender washers for marine applications, outdoor fixtures, or metal roofing installations. They prevent galvanic corrosion when paired with compatible metals like steel, while providing structural support.

Q: How do fender washer dimensions like "1 1/2" apply practically?

A: The "1 1/2"" in a 3/8 x 1 1/2 fender washer refers to its outer diameter (1.5"). This large surface area prevents fasteners from pulling through soft materials like wood or plastic and helps seal oversized holes.
