Alloy Steel Lock Washers Tec Series
TEC Series® washers keep joints secure using tension, not friction as with traditional washers. TEC washers consist of a pair of washers with cams on one side and seizing ridges on the other. The cam sides are mated together with a mild adhesive, and installed between the bolt head or nut and the joint material.
As the bolt or nut is tightened, the seizing ridges cause one half of the washer to be seated to the bolt or nut, while the other half is seated to the joint material.

Features and Benefits
TEC Series® washers are thoroughly tested in several stages of production to ensure a high level of quality Sherex customers have come to expect. Each TEC Series® washer is laser etched with a production lot number, part size, and coating to enable full traceability and easy identification.
TEC Series® washers are manufactured in an ISO-Certified Facility and are fully RoHS compliant.
Installation
When installing TEC Series® 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 Sherex.
Removal and Reuse
Removing TEC Series® washers requires no special tools or procedure. Simply untighten the joint in the normal method and check the washer to ensure cam faces disengage.
While TEC Series® washers are usually reusable, washers should always be inspected for deformation or excessive wear before reuse. If washers appear deformed or heavily worn, discard and use a new pair.
Application Examples
TEC Series® wedge locking washers can be used to protect joint integrity in a wide variety of joint types, including:
Tapped Hole
Counter Bore
Stud Bolt
Large Hole (For large/slotted holes and painted or soft contact surfaces, use Enlarged OD TEC Series Washers)
As the bolt or nut is tightened, the seizing ridges cause one half of the washer to be seated to the bolt or nut, while the other half is seated to the joint material.

TEC Series® washers are manufactured in an ISO-Certified Facility and are fully RoHS compliant.
Installation
- To install the TEC Series® Washer, place the preassembled pair between the nut or bolt and the joint material.
- 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.
- Install TEC Series® washers using standard tools according to TEC Series Torque Guidelines. Retightening is not needed.
- The use of lubricants is highly recommended when installing TEC Series® washers. A high quality lubricant designed to prevent seizing will reduce friction during installation and improve the consistency of clamp load in joints.
