High-Strength Thin Sheet Joining Solution: Self-Clinching Fasteners
In modern industrial design, where lightweight structures and high-density packaging are critical, creating stable, high-torque, and high-pullout threaded connections in thin sheet metals remains a fundamental challenge. Engineered specifically to eliminate the hassles of thin-plate tapping and heat distortion caused by welding, our Self-Clinching Fasteners Series—including clinching nuts, studs, and standoffs—delivers a permanent, high-precision, and cost-effective structural anchoring solution.
Core Advantages & Technical Highlights
Plastic Flow Cold-Forging Technology: Installed using standard press machines, our fasteners feature a specialized knurl or rib design that forces the ductile host sheet material to cold-flow into the fastener's undercut recess. This mechanical interlocking creates an exceptional resistance to both push-out and torque-out forces, preventing joint failure even under high-vibration environments.
Zero Thermal Stress & Coating Protection: Unlike traditional weld nuts, the cold insertion process generates no heat, completely protecting pre-painted, galvanized, or anodized sheet surfaces. This removes the need for secondary touch-ups, grinding, or re-plating, significantly cutting down production cycles.
Flush Mounting & High-Precision Threads: Once installed, the reverse side of the sheet remains perfectly flush, preserving internal spatial layout and sleek external aesthetics. All threads strictly adhere to ISO/ASME standards, minimizing cross-threading on automated assembly lines.
Technical Specifications
Applicable Sheet Hardness: Cold-rolled steel and aluminum alloy sheets below HRB 80; stainless steel sheets up to HRB 88 (utilizing specially hardened stainless fasteners).
Sheet Thickness Range: Suitable for sheets as thin as 0.8 mm without the risk of burn-through.
Material Options: Carbon Steel (Zinc / Zinc-Nickel plated), 300/400 Series Stainless Steel, and High-Conductance Copper Alloys.
Thread Sizes: Metric M2 to M10; Unified #2-56 to 3/8-16 (custom lengths and non-standard drawings welcomed).
