Product information

Expander connectors, also called expanding tube connectors, are available for square tubes or profiles with external dimensions from 18 x 18 mm to 45 x 45 mm inclusive, and for wall thicknesses of 1.5 mm to 2.0 mm inclusive
Thread sizes M6, M8 and M10
Available without or with 1 or 2 separate nuts
Can also be combined with hexagonal screws to DIN933, hexagonal lock nuts (DIN985) and stainless steel hexagonal nuts (DIN985)
The action of tightening the nuts (via the screw or threaded rod) expands the connector until it is firmly secured in the tube or box-section profile
Simple method for creating joints between square tubes without having to weld or use adhesive. Strong enough to withstand tensile forces.
Multiple possible uses such as for tube extension and demountable frames, e.g. for racks and shelving, exhibition stands, cages, aviaries, etc.

Material: Plastic insert - PA (polyamide), nut - galvanised steel
Colour: plastic insert – black, nut - zinc-coloured
