Why Choose Grade 8 Yellow Zinc Lock Washers?

Our Grade 8 yellow zinc lock washers at AlbanyCountyFasteners.com are engineered for superior strength and secure fastening in high-vibration, high-stress environments. Also known as Grade 8 yellow zinc split lock washers, these washers are made from medium carbon alloy steel, heat-treated to achieve a minimum tensile strength of 150,000 PSI per SAE J429 specifications. The yellow zinc plating provides 2-3 times more corrosion resistance than clear zinc, ideal for sheltered outdoor applications. Available in split ring or high collar designs, they create spring-like tension to prevent fastener loosening. Offered in imperial sizes like #2, #4, #6, #8, #10, 1/4", 5/16", 3/8", 1/2", 5/8", and 3/4", they meet IFI tolerances and are perfect for heavy machinery, automotive, and construction projects.

  • High Strength: 150,000 PSI tensile strength for demanding applications.
  • Corrosion Resistance: Yellow zinc plating for enhanced durability.
  • Vibration Resistance: Split or high collar designs prevent loosening.
  • Versatile Sizing: Compatible with common bolt and screw sizes.

Applications for Grade 8 Yellow Zinc Lock Washers

Grade 8 yellow zinc split lock washers are designed for projects requiring high-strength, corrosion-resistant fastening in high-vibration settings. Their versatility makes them suitable for:

  • Heavy machinery and equipment assemblies
  • Automotive engine and chassis components
  • Construction and structural connections
  • Industrial systems with high mechanical stress

Frequently Asked Questions (FAQ)

What are Grade 8 yellow zinc lock washers?

Grade 8 yellow zinc lock washers are high-strength washers made from medium carbon alloy steel with a yellow zinc coating, featuring split or high collar designs to prevent fastener loosening under vibration.

How do Grade 8 yellow zinc lock washers differ from stainless steel lock washers?

Grade 8 yellow zinc lock washers offer higher tensile strength (150,000 PSI) but moderate corrosion resistance, while stainless steel lock washers provide better corrosion resistance for harsh environments.

Are Grade 8 yellow zinc lock washers suitable for marine environments?

These washers are corrosion-resistant for sheltered outdoor settings. For marine or highly corrosive environments, 316 stainless steel lock washers are recommended for superior durability.

What tools are needed to install Grade 8 yellow zinc lock washers?

No special tools are required. Use a standard wrench or screwdriver compatible with the bolt or screw head. Place the washer between the fastener head and the surface, tightening to engage the locking tension.

How do I choose the right size Grade 8 yellow zinc lock washer?

Select based on the bolt or screw size and application requirements. Common sizes include #2, #4, #6, #8, #10, 1/4", 5/16", 3/8", 1/2", 5/8", and 3/4" inner diameters. Check sizing charts or consult our team for guidance.
