## Summary description

Koelner threaded self-clinching nuts 5×8 mm, pack of 16. Self-clinching (press-in) fasteners designed to be installed into thin sheet metal to provide permanent internal threads. Suitable for creating M5-type threaded points in panels where a reliable, low-profile nut is required. Used in electronics enclosures, sheet-metal assemblies and equipment chassis.

## Long description

Koelner threaded self-clinching nut 5×8 mm, pack of 16 are press-in fasteners engineered to create permanent internal threads in thin sheet metal. These clinch nuts install into prepared holes and, after pressing, form a secure, low-profile M5-type threaded point that resists rotation and pull-out under normal assembly loads. Designed for use in electronics enclosures, sheet-metal assemblies and equipment chassis, the nuts provide a repeatable and robust threaded attachment where welded or tapped threads are impractical.
Advantages
Self-clinching nuts deliver consistent thread alignment and strong retention in thin panels without requiring thick material or complex secondary operations. Their low-profile design minimizes protrusion on mating surfaces and keeps assembled components compact. The press-in installation creates a permanent metallic bond to the host material that improves load distribution and reduces the risk of thread stripping compared with simple sheet-metal screws.
Suitable for
Creating M5 threaded attachment points in thin sheet-metal panels
Mounting circuit boards, panels, and brackets inside enclosures
Chassis and equipment assemblies where space is limited
Applications requiring vibration-resistant threaded fasteners
Key specifications
Thread size: M5-type internal thread
Body dimensions: 5 × 8 mm (nominal clinch body size)
Finish and base material: metal self-clinching construction suitable for sheet-metal mounting
Package quantity: 16 pieces per pack
How to use
Drill or punch the panel hole to the recommended diameter for a 5×8 mm self-clinching nut and ensure the hole edges are free of burrs. Position the clinch nut perpendicular to the panel and press it into place using a controlled press or clinching tool until the nut shoulder embeds and the knurled or serrated body compresses to form a permanent interference fit. After installation verify that the internal thread is fully formed and use an M5 screw or bolt of appropriate length and grade for the application. Avoid over-pressing which can distort the thread profile.
Usage recommendations
Use these Koelner clinch nuts in panels of the recommended thickness range for reliable retention; consult material specifications to confirm compatibility. When assembling electronics or sensitive equipment, install nuts with a calibrated press and inspect each installation for correct seating and thread integrity before final assembly.
