Tinnerman® Expansion Type Plastic Fasteners


Expansion Nut

Expansion Nuts offer the designer a range of head types and diameters and the opportunity of providing a reusable thread form into blind box or channel sections where there is no access to attach a mating nut.

The Expansion Nut is simply pushed into the mating hole whereupon it expands and clicks into place, engagement of the mating screw then expands the nut further ensuring a secure vibration tight joint.
