PennEngineering® Broaching Standoffs - Types KFE, KFSE - Unified KFSE-143-24

KFSE broaching standoffs are threaded fasteners designed for unplated mounting holes in PC boards, providing a permanent axial attachment through knurled shank interference. They are specified for use with materials such as aluminum, acrylic, casting, and polycarbonate, and feature axial grooves that broach the material to resist rotation. The KFSE-143 variant has a 0.143-inch shank diameter and a 24-slot thread length, with a minimum hole size of 0.143 inches and a maximum sheet thickness of 0.22 inches. Pullout performance is enhanced by the broach design, and installation requires a non-plated hole to avoid damage to copper traces. These standoffs are compatible with standard automated assembly processes and are intended for stacking or spacing applications.
