We distribute – Anti Vibration TEC Series washers, Disc-Lock washers and Disc-Lock nuts – feature our proven wedge locking technology. This technology utilizes tension, rather than traditionally-used friction, to secure fastened joints in high vibration and load applications.
Locking Washer Technology : Chose between Temporary ( TEC Series) OR Permanent ( DISC LOCK) installation
DISC LOCK locking washers, recommended for applications with permanent joints, where fasteners will NOT need to be removed
TEC series locking washers, recommended for applications where fasteners and washersmay need to be removed and/or reused.
TEC Series and Disc-Lock Washers are offered in glued pairs; each washer has a cams on one side and radial teeth on the other side. The cam sides are glued together. During installation, the radial teeth cause ½ of the washer to be seated to the bolt or nut, and ½ to be seatedto the base material.
When the joint is exposed to heavy load or vibration, the bolt or nut will attempt to loosen. Because the TEC Series or Disc-Lock washer’s radial teeth are seated to the base material and the bolt or nut, the loosening movement is forced into the cams between the washer pair.
Because the cam angles are greater than the thread pitch, a wedge effect is created by the cams, preventing the bolt or nut from rotating loose.
Locking Nut Technology
Disc-Lock Nuts are two and three piece nuts that utilize the same cam wedge locking technology: when the joint is subjected to heavy shock or vibration, the interlocking cams create a wedge effect because the cam angles are greater than the thread pitch, securing the joint.
