TR Self-Clinch Clip-on Stand-off Installation

The TR Self-Clinch Clip on Standoff nut can be installed into a pre-punched or pre-drilled hole using a press capable of a squeezing action, causing the parent material to flow in to the specially designed under head configuration offering a load bearing joint.

Select the appropriate hole size from the table below for the stand-off size required. Punch the hole diameter into the sheet material. Place the stand-off spigot end into the hole on the side opposite the mating face. So that stand-off rests on the head.  Ensure both plate and stand-off are aligned along the same axis.  If the stand-off is not seated ‘square’ in the hole, the joint will be imperfect and mating threads will mis-align. Using a profiled punch, apply only sufficient pressure to ‘squeeze’ the head into the parent sheet metal.  The fastener when properly installed should be flush with the sheet metal with the clip spigot left clear and square to the sheet to accept a mating component.
