Technical Features
- Split lock design: The open split in the washer creates two sharp edges that bite into both the fastener and the mounting surface, generating friction that resists rotational loosening.
- 3/8" sizing: Matched to standard 3/8" threaded fasteners, ensuring proper load distribution across the bearing surface without over- or under-sizing.
- Box of 100 units: Bulk packaging reduces per-unit cost and ensures an adequate supply for multi-fastener assemblies or ongoing maintenance tasks.
- 3.91 lb box weight: Provides a practical reference for shipping and jobsite inventory management when ordering in quantity.
Applications
- Securing bolts and nuts in mechanical assemblies subject to vibration, where fastener loosening presents a safety or performance risk.
- General construction and structural fastening applications using 3/8" threaded hardware.
- Equipment assembly and maintenance tasks requiring a reliable, friction-based anti-loosening solution at the fastener interface.
- Bulk supply for contractors, maintenance facilities, or workshops maintaining an inventory of standard 3/8" fastener hardware.
