Premium Material & Design:
A4-80 stainless steel (316): 1000+ hours salt spray resistance, suitable for coastal, chemical, and medical environments (pH 2-12).
Countersunk head (ISO 10664, 82° angle): Flush installation in pre-drilled countersinks (depth tolerance ±0.1mm), achieving seamless surfaces in stainless steel facades and medical devices.
Knurled stripe body (0.4mm pitch): Enhances anti-rotation in soft metals (aluminum, copper) and composites, with 30% higher torque resistance than smooth bodies.
Performance Specs:
Hollow body: Weight 40% lighter than solid rivet nuts, with tensile strength 800 MPa and shear strength 600 MPa, exceeding ISO 14580 for 1-3mm materials.
Thread accuracy: 4H class tolerance, ensuring smooth engagement with titanium and stainless steel screws.
Installation & Compliance:
Blind installation: Requires specialized countersink rivet nut tools, suitable for single-sided access in pipes, tubes, and closed-section structures.
Surface finish: Electropolished (Ra ≤0.5μm) for hygiene compliance (ISO 13485 for medical devices, NSF 51 for food contact).
Size Range:
Thread sizes: M3-M8 (metric), 1/8"-5/16" (imperial); head diameter: 6-14mm; body length: 6-15mm, compatible with material thickness 1-4mm.
