Advanced TCA^® specifications for telecom rack systems require two clinching fasteners: a self-clinching alignment pin and a captivated screw.

The PEM^® Type TPXS^TM pin meets the ATCA PICMG 3.0 specification for a 3mm alignment pin. The 15° tapered point makes engaging the mating hole easy.

PEM^® captive floating retention screws, with M3 threads and 0.51 mm of radial float, offer an ATCA style mounting solution. These thumb screws provide the added advantage of an anti cross-thread feature making thread engagement quick and easy. Types PF11M and PF12M provide retainer shoulder for enhanced visual verification of installation.
