Square Taper Washer - Split Spring Lock Prevents Loosening
Usage scenarios:
- In vibrating machinery like motors and gearboxes to stop nuts and bolts coming loose from constant motion.
- On automotive and agricultural parts (axles, linkages, PTO shafts) where reliable fastening under load is critical.
- For small equipment, appliances, and furniture with rotating or moving parts that can work free over time.
Product features
The square taper washer features a split, spring-like geometry with one end raised to create a taper that centers the fastener and distributes load beneath nuts and bolts. Its spring action applies continuous axial pressure to the nut or bolt, resisting vibration and preventing loosening to improve joint reliability. Designed for compatibility with standard hardware, the compact, durable construction delivers easy installation, consistent clamping force, and reduced maintenance in high‑vibration applications.
