Datasheet – Self-Clinching Grounding Standoffs

Self-Clinching Grounding Standoffs

Self-clinching grounding standoffs are press-fit spacers designed for thin sheet metal assemblies where a reliable, repeatable electrical grounding path is required. Once installed, the fastener provides controlled stand-off height while maintaining metal-to-metal contact for conductivity.

Typical applications

Grounding points and conductive stand-offs in enclosures
EMI/EMC-sensitive assemblies
Electronics chassis and control panels

Installation

Punch or drill the recommended mounting hole
Use a parallel pressing tool (arbor or pneumatic press)
Ensure sheet thickness meets the minimum requirement

Dimensions and tolerances

Dimensions shown are typical installation data. Keep the specified hole diameter and minimum sheet thickness to achieve proper clinch performance.
Dimension key: L = length, F = flange diameter (nominal), D = body diameter, CL to Edge = minimum centreline-to-edge distance.
