PEM SNAP-TOP® standoffs, including the SSA-156-18 variant, are self-clinching fasteners designed for permanent installation into metal panels or PC boards. The SSA type is made of aluminum and installed by pressing into a properly sized hole, with a holding force determined by material hardness and panel thickness. It is available in lengths designated in 32nds of an inch, with the 156-18 designation corresponding to a length of 0.562 inches. The standoff features a spring action to secure PC boards and subassemblies without screws, reducing assembly parts and risk of circuit damage. A registered dimple identifies genuine PEM units.
PEM SNAP-TOP® Standoffs (Types SSA, SSS, SSC) are designed for permanent installation into metal panels or PC boards.
These all-metal standoffs use a spring action to hold PC boards and subassemblies securely, while allowing for quick removal. Screws and other threaded hardware are eliminated. This means less parts to handle during assembly and less risk of damaging delicate circuitry because of loose parts falling into your equipment.
These standoffs are permanently installed in the panel by squeezing them into a properly sized hole using any standard press.
