is a thread-cutting fastener designed to meet the demanding requirements of thermoset plastics with easy assembly coupled with a strong, reliable joint to ensure optimized assembly performance.
Our team of experts is ready to support you.
FEATURES AND BENEFITS
- Provides an asymmetrical 30º thread profile, inclined towards load surface to increase friction (FR) between the application and the fastener
- Reduction in radial stress
- Reduction in back-out caused by relaxation
- Increase in strip resistance
- Elimination for the need in supplementary locking devices
- Optimal thread pitch allows for deeper thread engagement
- Increase in pull-out strength
- Increase in resistance to vibration loosening
- Increase in load-carrying capability
- The recessed thread root allows space for displaced material
- Minimization in installation torque
- Miniziation in the risk related to clogging and galling of threads during assembly
- The shank slot minimizes chip production
- Through hardened to Rc 33-39
