Standard Disc-Lock Washers
The Standard Disc-Lock Locking Washer is both a vibration-proof locking device and a heavy duty structural locking device recommended for the most stressful applications.
Thicker and wider in diameter for better performance
Coated with Delta Protekt with a minimum 600 hours of salt spray.
Can be used with Grade 2,5,8 & even stronger bolts.
How it works
Under vibration, the nut will attempt to rotate loose.
However, a jamming effect is created as the interlocking cams and the non-slip ridges of the Disc-Lock Washer work simultaneously.
This prevents loosening and further locks the assembly, thereby maintaining joint integrity.
Why choose disc-lock?
Helping businesses boost production and cut maintenance costs by eliminating downtime brought on by regular fastener failure.
Proven to have outperformed other types of loose, threaded, washered or pinned fixings under conditions of intense vibration.
