Anti-Loosening Screw

POWERLOK

POWERLOK

Ridge Friction Type

Thread is TAPTITE (triangular) shape. This thread is constructed with combined included angle of 30/60 deg., which gives an excellent vibration proof and shock resistance by improving the lock action due to external thread interfering into internal thread, when this screw is fastened into tapped internal thread.

Applications

・Pre-tapped sheet metal.
Unfit if there is some variation in the accuracy of female-thread
・Case where cost reduction is intended from fastening with washers and adhesives
・Points requiring vibration resistance
・Automobile, OA equipment, AV, mobile equipment, etc

FIT-TITE

FIT-TITE

Ridge Friction Type

The increased number of contact points provides a higher loose-proof effect.Because it is well considered about torque which relates interfering with inner diameter of female thread, higher usability can be provided even when the internal thread shapes vary.

Applications

・Personal computers, OA equipment, printers, mobile communication devices, and cellular phones
・Cameras and watches
・Automobiles, electric tools, air conditioning equipment, and other products

NK GRIP

NK GRIP

Adhesive applied Type

This is a screw coated with a microcapsule in which is sealed an epoxy-based adhesive. When the screw is screwed into a female thread, the capsule is destroyed, and the adhesive oozes out, to provide a high fastening force with hardening.

Applications

・Fastening point where loosening must be absolutely avoided
・Fastening point where sealing effect is desired
・AV, mobile equipment, digital electric home appliance, OA equipment, etc

SOFTLOK

SOFTLOK

Nylon Coated Type

Nylon is spread on thread surfaces. When Softlok is screwed into the tapped internal threads or nuts, a higher friction resistance is generated between the gap between screws and female threads because of the elasticity of the nylon, thereby producing a great loose-proof effect.

Applications

・Fastening point where loosening must be absolutely avoided

LLS

LLS

Nylon Inserted Type

Screw with a nylon press fit in the cut groove provided in the screw thread. The nylon is deformed as the screw is screwed in, producing a large loose-proof effect thanks to a high frictional torque due to its wedge effect.

Applications

・Case of fastening points subject to vibration and shocks such as automobile, motor, etc
・Case where it is expected as a point-adjusting screw
・Automobile, bicycle, OA equipment, AV, mobile equipment, digital electric home appliance, etc
