High reputation durable and convenient dual self lock washer
How does it work?
The Washers secure joints using tension rather than friction,as with traditional locking fasteners.The Washers consist of a pair of the Washers with cams on one side and radial teeth on the other.The cam sides are joined together with a mild adhesive,and installed between the bolt head and/or nut and the joint material.
During installation,the radial teeth cause one half of the Washer to be seated to the bolt or nut,while the other half is seated to the joint material.
When exposed to load or vibration,the bolt or nut will attempt to loosen.Since the radial teeth are seated to the mating surfaces,any movement in the loosening direction is forces between the cam.
Because the cam angle(α)of the Washers is greater than the thread pitch angle(β)of the bolt,a wedge effect is created by the cams,preventing the bolt or nut from rotating loose.Clamp load is maintained and the joint remains secure.
Characteristics and strengths
*Maintains clamp load in high vibration and load applications,thereby protecting the security of the joint
*Heavy duty,self-locking design
*For use with bolts up to Class 12.9,Grade 8
*Avaliable in SCM435/SAE4130 Alloy Steel,316L Stainless Steel,and 254 SMC Stainless Steel
*Provided in preassembled glued pairs
*Easy to install and remove with standard tools
*No retightening needed after installation
*Reusable-will not distort threads on bolt
*Vibration proof according to MIL-STD-1312-7/DIN 25201
*Can be used reliably for joints with short clamp length
*Secures joints with high and low preloads
How does it install?
*To install the Washer,place the preassembled air between the nut and/bolt and the joint material.See page for application examples.
*As the nut or bolt is tightened,one half of the Washer pair will be seated to the joint material and the other half will be seated to the nut or bolt.
*Tighten joints with the Washers using standard tools.Retightening is not needed.
*The use of ubricants is highly recommended when installing the Washers.A high quality lubricant designed to prevent seizing will reduce friction during installation and improve the consistency of clamp load in joints.
*When installing the Washers in a common application,expect an increase in required torque over recommended installaation torque to achieve proper clamp load and maximum joint safety.
Removal and reuse
Removing the Washers requires no special tools or procedure.Simply loosen the joint in the normal method and check the Washer to ensure cam faces disengage.
While the Washers are typically reusable,it should always be inspected for deformation or excessive wear before reuse.If the Washers appear deformed or heavily worn,discard and use a new pair.
Quality
Each the Washers manufacturing facility is led by a team of seasoned engineering professsionals charged with ensuring all products meet stringent quality requirements.Our facilities are certifiled to ISO 9001-2015,IATF16949,and utilize worldclasss testing equipment,including tensile testing,accelerated corrosion salt spray testing machines,torque testing,standard measurement and gauging equipment.
The Washers are manufactured in a facility which strictly adheres to multiple ISO certification standards,and are thoroughly tested through the production cycle to ensure a high level of quality.
