Professional Applications & Engineering Value
Engineered for industrial applications where vibration resistance and corrosion prevention are critical, these bronze split lock washers solve common fastening failures in machinery, automotive, and marine systems. The bronze material offers natural lubricity and resistance to galvanic corrosion when paired with dissimilar metals, while the split lock design creates continuous spring tension that counters rotational loosening. Meeting ASME B18.21.1 standards, these washers provide reliable performance in high-vibration environments where standard flat washers would fail, making them essential for industrial maintenance and heavy equipment applications requiring secure, long-term fastening solutions.
Specification Summary & Compliance
This bronze split lock washer features precise inch dimensions (ID: 0.26", OD: 0.487", Thickness: 0.062") compatible with 1/4" screw sizes. Manufactured to ASME B18.21.1 specifications for standard split lock washers, it maintains Rockwell B90 hardness for consistent spring performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in global industrial markets.
