A MISSION TO REINVENT BEST PRACTICE

REVOLUTIONARY NUT TECHNOLOGY

The Segnut system is a world-first, proprietary nut and bolt product. It has a patented segmented inner section consisting of three segments held captive by an outer sleeve. When the outer sleeve is turned a few degrees in the tightening direction, the Segnut releases from the bolt and falls away.

A basic rattle gun and impact socket are the only tools required to remove the Segnut.

AWARD WINNING DESIGN

In 2016, Segnut was a finalist in the Emerging Innovation Category in the West Australian Innovator of the Year awards.

We have a focus on continued innovation and support this with a specialist innovation team and facilities.

(1) Segmented inner nut
The three segments enable the nut to release away from the bolt/stud threads.

(2) Outer sleeve
Holds the three segments together so that a bolt clamp force can be generated. The sleeve’s profile has clearance to allow segments to move away from the bolt/stud when it is rotated relative to the inner nut.

(3) Inner nut corners
Prevents the outer sleeve from moving upward and provides flats for a standard hex wrench/socket.

(4) Hardened washer

(5) Dilation
Force is generated as the bolt is tightened. This force is resisted by the outer sleeve, holding the inner segments in place until it’s turned and the segments are free to release away from the bolt/stud.

(6) Extended thread length
The end of standard bolt/stud threads can sit up to two full threads below the end of the nut. This ensures that it is protected from debris and corrosion and may be re-used where regulations permit.
