The Stanley WedgeLock™ is a fastening system featuring an integrated design that wedges the fastener in place to resist loosening. The Stanley® WedgeLock™ system is comprised of four parts. The wedge ramps intregrated in the fastener head bearing surface mirror and mesh with ramps designed into the top side of the WedgeLock™ washer. The bottom side of the Wedgelock™ washer incorporates locking serrations that create a secure locking bond when assembled properly. A SEMS assembly process permanently retains the washer to the fastener.
The most common fastened assembly issue is vibration loosening. Vibration loosening carries a huge product liability impact that can ultimately threaten your financial bottom line. The negative effects of vibration loosening include:
- Liability of injury to end user
- Perception of poor quality
- Costly field repair
