EP 5# Lock Washer (10 pcs)

EP 5# Lock Washer – secure screw connections in RC modelling

The EP 5# lock washer is a safety washer for bolted joints in modelling. With an inner diameter of 5 mm and a pack of 10 pieces, this set is ideal for RC cars, planes, and helicopters.

• 10 lock washers with 5 mm inner diameter – sufficient for multiple connections
• Reliably prevents screws from loosening due to vibrations – enhances operational safety
• A well-fitted lock washer ensures lasting hold without retightening
• Versatile use in RC cars, boats, drones, and other models

What sets the EP 5# lock washer apart

Unlike flat washers, the lock washer creates an elastic preload that securely fixes the screw even under strong shocks. This extends maintenance intervals and prevents unexpected failures during operation.

Ideal for RC enthusiasts

Especially suitable for model builders who maintain and optimize their own vehicles and flying models. Also indispensable in workshops that perform frequent screwing work.

How to use the EP 5# lock washer

Place the lock washer between the screw head and a flat washer, or directly under the nut onto the threads. Tighten the screw to the recommended torque – the lock washer provides the necessary tension. Upon disassembly, the rings can be reused if not plastically deformed.
