Threaded self-clinching nut (clinch nut) Koelner 5×8 mm, pack of 16

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.
