Worlds Strongest Locknut

Unique - One Part / Two Piece Design

Security Locknuts are designed so that the insert raises away from the nut body upon application. This creates “isolation” from the load where the nut body carries the load

and the insert does the locking, regardless of your ability to achieve “perfect” preload.

Metal locking insert made with proprietary metal and processing techniques for maximum performance Industry standard nut body with features for locking insert Locking insert pressed into the nut body and ready for installation on a bolt

Locking insert lifts and separates from the main nut body on the base and side walls when the bolt is installed. This separation isolates the clamping load from the locking function

Unique - One Part / Two Piece Design

Product Performance

Method Installed and tested on real world applications IFI 100/107 Standards for Prevailing Torque Locknuts NASM 1312-7 Test for fastener performance in vibration conditions 50 on/off test Details Every year millions of Security Locknuts are installed on hundreds of products operating in a wide range of environments. The Security Locknut meets or exceeds the Industrial Fastener Institute 100/107 Standards. This standard establishes the dimensional, mechanical, and performance requirements for prevailing-torque type steel nuts The Security Locknut has been tested using this accelerated life test. A summary of the test details are shown on the following pages .

Test measures the prevailing locknuts ability to maintain its function after installation and removal up to 50 time. Security Locknut outperforms all tested competitor s.

NASM 1312-7 Vibration Test

Initial Test Results:

•

The Security Locknut performs better than or equal to all other prevailing torque locknuts at

•

preventing joint loosening (other products tested include Nyloc, 3-point deformed, and Flexloc).

The Security Locknut out performs all other locknuts by staying securely connected the bolt after the initial tension is lost. This has proved to be a significant benefit on installations where complete separation of the nut and bolt would cause machinery down time or a potential safety issue.

•

Follow up Testing and Product Development: After detailed examination of locknut conditions required to maintain maximum bolt tension under heavy vibration conditions we were able to isolated design parameters that had the most significant impact. Follow up design changes on select products produced results on the vibration test that exceed all other products tested.
