Micro self-clinching standoff fasteners suit electronic applications
Penn Engineering is launching new PEM micro self-clinching standoff fasteners for spacing or stacking applications in compact electronic assemblies. These micro standoffs are described as practical, cost-effective and permanently secure, enabling quicker assembly of devices ranging from handheld consumer electronics to medical equipment.PEM Type MSO4 micro self-clinching standoffs are manufactured from 400 series stainless steel and are engineered with threads as small as M1.0 (or #00) and in lengths as short as 2mm (or 0.080inch). They can be installed into sheet metal (including 300 series stainless steel) as thin as 0.4mm (0.016inch) with a maximum hardness of HRB 88 on the Rockwell B scale.
The micro standoffs are clinched into place by simply pressing them into a properly sized mounting hole using a punch and anvil until the fastener's head is flush with the substrate. Upon installation, they become a permanent part of an assembly, will not loosen or fall out, and provide strong and reusable load-bearing threads. Installing them automatically can further reduce costs by accelerating production and eliminating any need to handle the small parts.
Detailed specifications (Bulletin MSO4) and free part drawings (PEM CAD library) for these Rohs-compliant fasteners can be accessed via the company's website.
