Key Features & Benefits at a Glance
- Superior corrosion resistance with Acetal Plastic construction, eliminating rust and chemical degradation in harsh environments
- Reliable spring locking action prevents loosening from vibration and thermal cycling in dynamic assemblies
- Exceptional temperature resilience maintains performance from -40°F to 212°F for diverse operating conditions
- High mechanical durability with Rockwell M80 hardness ensures long service life under repeated load
- Dual-standard compatibility fits both 5/16" (inch) and M8 (metric) screw sizes, simplifying inventory
- Precision dimensional control with consistent ID/OD/thickness for uniform clamping force and ease of installation
- Environmental compliance meets RoHS 3 (2015/863/EU) standards for restricted substance control
Professional Applications & Engineering Value
Engineered for demanding industrial fastening applications, this Acetal Plastic Spring Lock Washer solves critical assembly challenges where metal components fail. Its non-conductive, corrosion-resistant properties make it ideal for electrical enclosures, food processing equipment, and marine hardware, preventing galvanic corrosion and contamination. The spring lock design delivers consistent preload to counter vibration-induced loosening in machinery, automotive, and HVAC systems. With a temperature range of -40°F to 212°F, it performs reliably in both freezing and moderate heat conditions, while the white color allows for visual inspection and compatibility with color-coded assemblies. The dual screw size compatibility (5/16" and M8) streamlines procurement for global manufacturing operations.
Specification Summary & Compliance
This washer features precise dimensions: 0.328" ID x 0.66" OD with a thickness of 0.043-0.053" and overall height of 0.08". Manufactured from Acetal Plastic with Rockwell M80 hardness, it conforms to standard inch/metric fastening requirements for 5/16" and M8 screw sizes. The product is fully RoHS 3 (2015/863/EU) compliant, ensuring adherence to hazardous substance restrictions, and operates effectively within a temperature range of -40°F to 212°F.
