Datasheet – Self-Clinching Spring Top Standoffs

Self-Clinching Spring Top Standoffs

Self-clinching spring top standoffs provide a permanent, load-bearing spacer in thin sheet metal assemblies. The spring top feature helps retain panels or components during assembly, supporting quicker handling and more consistent alignment.

Typical applications

• PCB and electronics enclosure spacing
• Panel-to-panel separation and alignment
• Equipment covers and access panels
• General sheet-metal assemblies

Installation overview

• Prepare the specified mounting hole in the sheet
• Insert standoff into the hole from the appropriate side
• Press in using a parallel acting press and flat tooling
• Verify seating and flange contact; do not over-press

Product table

Dimensions are provided as nominal values with tolerances where supplied. Units appear as supplied in the source data (inch for Unified; mm for Metric). This datasheet intentionally excludes manufacturer series and part numbers.

Handling and storage

Store in a clean, dry environment. Keep items sealed until use to minimise contamination and cosmetic damage. Avoid mixing different sizes in open bins to prevent mis-picks.

Disposal

Dispose as scrap metal in accordance with local regulations.
