Self-clinching flush-head pins
PEM type TP4 self-clinching flush-head pins can be installed permanently in stainless steel sheets down to 1.00mm "thus helping to contribute to the achievement of thinner, lighter stainless designs", says Michael Rossi, PennEngineering. "These fasteners satisfy a wide range of positioning, pivot, and alignment applications."
Promoted by the company as "a practical alternative to welding" the pins are manufactured from 400 series stainless steel. They resist corrosion and are heat-treated.
"As far as installation is concerned the pins are placed in prepared mounting holes, then squeezed using a PEMserter tool or standard press. The chamfered end of the pin makes alignment of the mating hole easy", says Michael Rossi. "Once installed, the pins create a flush-head assembly and lock securely with high push-out resistance. They become a permanent part of the stainless assembly."
