Stainless 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.

Quality and Traceability

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.

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.
