The DuraForceTM Fastener System is a new reusable fastener designed to withstand vibratory environments. It has been awarded a patent and testing shows it holds tight under extreme vibration when others fail. Finite element analysis was used to determine the optimal design specifications. The system uses a lateral force integrated into the threaded fastener to deflect shock and vibration in a simple and reusable way. It can eliminate machine failures and downtime while providing custom solutions for vibration needs, especially in severe environments.

Proudly Presents
Introducing a Vibration-Proof, Reusable fastener system: DuraForce™
The American made DuraForce™ Fastener System is the one of the most revolutionary improvements to the
fastener industry in the last 85 years.
DuraForce™ Makes Vibratory Environments SAFE, and has been awarded Patent# 8967932 b2
THE PROOF IS IN THE TEST RESULTS FROM THE JUNKER’S TEST MACHINE: WHEN OTHERS FAIL DURAFORCE™ HOLDS TIGHT
AND WILL NOT LET GO!

2. NCSU Department of Mechanical and Aerospace
Engineering conducted a semester long FEA Modeling
Program of the DuraForce™ Fastener System to
parametrically analyze the effects of strain and
displacement between annulus and compression collar by
varying component dimensions and geometry to determine
the most ideal design specifications.
DuraForce™ Fastener System uniquely CAPTURES, RETAINS & DELIVERS GREATER ENERGY BACK to an assembled joint to
ultimately deflect shock and vibration.
1. NEVER BEFORE has a lateral force been integrated into a threaded fastener system to deflect shock and vibration.
2. FEA MODELING has been implemented to determine the MOST OPTIMUM PRODUCT DESIGNS to meet and/or exceed
the performance requirements for specific applications and/or environments.
3. 2 RELATIVELY SIMPLE PARTS create a re-usable, free-spinning, single-threaded component, self-locking, vibration-proof
fastener system that is as EASY TO INSTALL AND DISMANTLE as a standard nut utilizing conventional tools.
The exploded Finite Element Analysis (FEA) illustration to
the right demonstrates the locking effect of the annulus
upon the threaded bolt once properly assembled
