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.
When the joint experiences vibration, the bolt or nut attempts to loosen. Since
one half of the washer is seated to the bolt or nut, it attempts to rotate as well.
Because of the cam angle () of the washers is greater than the thread pitch (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.
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.
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.

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.
APPLICATION EXAMPLES
TEC Series wedge locking washers can be used to protect joint integrity in a wide variety of joint types, including:
Tapped Hole Stud BoltCounter Bore Large Hole*
PROVEN APPLICATIONS
in a wide variety of high stress,
corrosive, and vibration-sensitive
* For large/slotted holes and painted
or soft contact surfaces, use
Enlarged OD TEC Series Washers
TEC Series wedge locking washers are not recommended for mating surfaces that are not
locked in place or are harder than the washers. TEC Series washers are not recommended
for use in non-preloaded joints.

test, considered the most severe vibration test for
bolted joints, is used to determine the point at which
a bolted joint loses its preload when subjected to
shear loading due to transverse vibration.

CLINCH NUTS
Sherex offers three different kinds of clinch
nuts to meet the specific requirements of the customer’s application. Sherex clinch nuts can
be used in various high strength steels such as
dual phase alloy, HSLA, and TRIPS to meet class
10 nut strength requirements. Sherex clinch nuts can be used in any material that offers access
from both sides of the base material.
