HEICO-LOCK®
Ring Lock Washers

HEICO-LOCK^® Ring Lock Washers provide high-quality, user-friendly bolt securing for the most demanding of applications and are ideal for repeated use.

The ring locking system guarantees that the two wedge lock washers are always fastened in the correct position with the wedge shaped cams on the inside and the radial teeth on the outside. This means that the bolt locking system is always easy, safe and quick to install, even for non-specialist users.

Design of the ring locking system

HEICO-LOCK^® Ring Lock Washers are supplied pre-assembled. The ring locking system consists of a polyamide ring (PA) and the already familiar HEICO-LOCK^® Wedge Lock Washers.

• Very easy to install and remove (ring locking system is supplied pre-assembled)
• Whereas the HEICO-LOCK^® Wedge Lock Washers secure the bolted connections reliably,
  the ring holds the two individual washers together in the correct position permanently
• Particularly suitable for dynamic loads – including when lubricants are used
• Also suitable for use with high-tensile bolts of 8.8, 10.9 and 12.9 and their respective nuts
• Available from M4 – M24 - custom sizes upon request
