  • Stress is minimized on plastic host
  • Joint Life - Increased in both static & dynamic stress
  • Strength - Torsional & Tensional improve by up to 50% for the same nominal diameter
  • Shorter fasteners and smaller diameters
  • Load Distribution - increased head diameter
  • Eliminate Inserts
Calculation Program
Delta Calc is a program that can calculate a foregoing dimensioning of the joint. This program aids in the dimensioning of the fastener and assists you in determining the load carrying ability and forecasted life of the joint. Contact an EFC Representative to learn how Delta Calc can benefit your current applications.
