Why Choose Aluminum Lock Washers?
Our aluminum lock washers at AlbanyCountyFasteners.com are designed for lightweight, corrosion-resistant fastening in low-stress, high-vibration environments. Also known as aluminum split lock washers, these washers are made from aluminum, offering excellent corrosion resistance, non-magnetic properties, and low electrical conductivity, ideal for indoor and outdoor applications where weight is a concern. Their split, helical design creates spring-like tension, gripping the fastener and surface to prevent loosening. Available in imperial sizes like #2, #4, #6, #8, #10, 1/4", 5/16", and 3/8", they meet ASME B18.21.1 standards and are perfect for electronics, aerospace, and lightweight assemblies.
- Lightweight: Aluminum reduces weight in sensitive applications.
- Corrosion Resistance: Resists rust in indoor and outdoor environments.
- Vibration Resistance: Split design prevents fastener loosening under stress.
- Non-Magnetic & Non-Conductive: Ideal for electronics and aerospace.
Applications for Aluminum Lock Washers
Aluminum split lock washers are tailored for projects requiring lightweight, corrosion-resistant fastening in low-stress, high-vibration settings. Their versatility makes them suitable for:
- Electronics and electrical enclosures
- Aerospace and lightweight structural assemblies
- Automotive components with aluminum fasteners
- Outdoor equipment with low mechanical stress
Frequently Asked Questions (FAQ)
Aluminum lock washers are lightweight, corrosion-resistant washers with a split, helical design, engineered to prevent fastener loosening under vibration in low-stress, non-magnetic environments.
How do aluminum lock washers differ from stainless steel lock washers?Aluminum lock washers are lighter and less strong but offer similar corrosion resistance for low-stress applications, while stainless steel lock washers provide higher strength for demanding environments.
Are aluminum lock washers suitable for marine environments?Aluminum lock washers are corrosion-resistant for general outdoor use but may not withstand prolonged saltwater exposure. For marine environments, 316 stainless steel lock washers are recommended.
What tools are needed to install aluminum 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 gently to engage the locking tension without deforming the aluminum.
How do I choose the right size aluminum 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", and 3/8" inner diameters. Check sizing charts or consult our team for guidance.
