Description de produit
Heat Treated Black Oxide Coated High Load Capacity Custom Knurling Pattern Self Clinching Nut
High-Performance Self Clinching Nuts for Demanding Applications
Our heat treated self-clinching nuts deliver exceptional pull-out resistance up to 1500N with core hardness of HV450. The black oxide coating provides a non-reflective matte black finish ideal for optical equipment and concealed assemblies. Custom knurling patterns are engineered specifically for your parent material to ensure maximum grip without panel damage. Fast 48-hour sampling available.
Engineered for Extreme Load Conditions
Standard press nuts often fail under high axial loads, vibration, or thermal cycling. Our specialized heat treatment process achieves HV450 core hardness in carbon steel nuts while maintaining surface toughness for reliable clinching deformation. With pull-out forces reaching 1500N (M6 size), these nuts are built for heavy equipment and safety-critical applications.
Custom knurling patterns are precisely engineered based on your parent material's hardness and thickness. We analyze aluminum, mild steel, stainless steel, or plastic substrates to design optimal tooth profiles (depth, pitch, helix angle) that maximize anti-rotation torque while preventing panel cracking. The black oxide coating ensures non-reflective properties with basic corrosion resistance, perfect for internal assemblies. All products include installation force and pull-out force test reports. Backed by 15 years of manufacturing expertise.

Product Applications
Optical Inspection Equipment: Internal fastening for dark boxes and lens mounts; black oxide surface non-reflective, does not affect imaging.
Industrial Robot Arms: Sensor mounting at joints; high pull-out force resists acceleration/deceleration shocks.
EV Battery Swap Stations: Wear-resistant fasteners for battery locking mechanisms; heat treated for repeated insertion/removal.
Frequently Asked Questions
Can you handle complex custom designs and provide design optimization suggestions?
