Material & Design:
Carbon steel C1018 (ASTM A325) with dual zinc plating (blue-yellow, 10μm total thickness), passing 800 hours salt spray test, suitable for indoor/outdoor use.
Hollow body (wall thickness 0.6-1.5mm): 40% lighter than solid rivet nuts, with knurled surface (0.4mm depth) preventing rotational slippage in aluminum and steel sheets.
Performance Specs:
Tensile strength: 450 MPa, shear strength: 350 MPa, exceeding ISO 14580 requirements for sheet metal up to 3mm.
Flat head (ISO 7046): Flush installation in countersunk holes (depth ≥3mm), ideal for aesthetic applications like automotive body panels.
Installation Flexibility:
Blind-side installation: Compatible with manual or pneumatic rivet nut tools, reducing setup time by 30% in hard-to-reach areas.
Thread compatibility: 6H tolerance for metric (M3-M8) and imperial (1/8"-5/16") screws, with smooth internal threads for easy engagement.
Compliance & Finish:
RoHS 3.0 compliant, with optional passivation for food-grade applications (FDA 21 CFR Part 175.300).
Hex ground surface: 15% larger torque contact area than standard knurling, enabling 25% higher torque (30Nm for M6) without surface damage.
