PEM Fastener Insertion
Press-fit PEM fastener installation for sheet metal enclosures, panels, and brackets. Threaded studs, standoffs, and clinch nuts installed flush and permanently: no welding, no tapping, no loose hardware.
Fastener Types
Clinch Nuts
Self-clinching nuts (CLS, S, SP series) pressed into sheet metal to provide a permanent, load-bearing thread. Ideal for enclosure doors, covers, and access panels.
Studs & Pins
Self-clinching studs (FH, FHS series) for mounting PCBs, DIN rails, terminal blocks, and internal components without back-side access.
Standoffs
Blind and through standoffs (SO, BSO series) for PCB mounting, panel spacing, and stacked assemblies where controlled height is needed.

Applications
- Electrical enclosures: door hinges, latches, and grounding studs
- PCB and DIN rail mounting inside control cabinets
- Rack-mount equipment with captive nuts
- Panel-to-frame assembly without visible hardware
- Telecom cabinets and server enclosures
- Access panels and removable covers
- EMI/RFI shielding enclosures
- Any sheet metal assembly requiring flush, permanent threads
Why PEM Instead of Welded Studs or Tapped Holes?
- Flush finish: no weld spatter or back-side protrusion
- Stronger than tapped holes in thin sheet metal
- Reusable threads that won't strip under repeated assembly
- No heat distortion: critical for painted or coated panels
- Installed after punching/laser, before bending: fits the production flow
- Consistent torque values across the entire panel
