Proven Results
Disc-Lock® Locking Washer Junker Test

Disc-Lock® Wedge Locking Washers have been tested on a Junker Vibration Machine. The Junker test, considered the most severe vibration test for bolted joints according to DIN 65151, is used to determine the point at which a bolted joint loses its preload when subjected to shear loading due to transverse vibration.

When tested against a standard washer using the Junker test, Disc-Lock® Wedge Locking Washers remained secure under severe vibration conditions, while the standard washer loosened significantly.

Proven Applications
Disc-Lock® Wedge Locking Washers outperform conventional, split-ring, and other style washers in a wide variety of high stress, corrosive, and vibration-sensitive applications including:

Agriculture Equipment
Automotive
Construction Equipment
Heavy Rail
Logging Equipment
Marine
Military
Mining
Oil Drilling Equipment
Solar
Wind
Waste Management

Installation

To install the Disc-Lock® Washer, place the preassembled pair of washers between the nut and the joint material.
As the nut is tightened, one half of the Disc-Lock® Washer is seated to the joint material and the other to the nut.
Disc-Lock® Washers should only be used against flat, relatively smooth metal surfaces.
If the joint material is not metal, the Disc-Lock® washer may be used by securing the metal plate to the joint material in such a manner that the metal plate will not rotate.
A torque wrench is not required to install Disc-Lock® Washers.
An air-gun can be used when installing and removing Disc-Lock® Washers.
If installed correctly, the Disc-Lock® Washer will ensure that the fastener remains secure, and will not require any re-tightening.

Torque Guidelines
When installing Disc-Lock® Washers in a common application, expect an increase in required torque over recommended installation torque to achieve proper clamp load and maximum joint safety. Due to varying installation conditions and customer-specific applications, additional information and torque recommendations are available by contacting Engineering support at Disc-Lock®.
