Streamlining Assembly with Cost-Effective Reliability: Precision High-Tensile Grooved Pins

As a trusted global manufacturer of precision fasteners, we introduce our next-generation High-Tensile Grooved Pins. Featuring three precisely swaged longitudinal grooves on the pin surface, these components utilize the principle of metallic elasticity to achieve a secure, interference fit through a simple "press-in" installation into standard drilled holes—making them the ultimate solution for optimizing assembly lines and slashing manufacturing overheads.

Key Product Features

  • Eliminates Reaming for Drastic Cost Reductions: The unique swaged grooves expand the pin's diameter. When pressed into a standard drilled hole, the raised crests are elastically compressed, creating a powerful, uniform holding force. This completely eliminates the need for expensive reaming operations, dramatically lowering the cost per hole.

  • Exceptional Shear Strength & Vibration Resistance: Engineered from single-piece construction, the radial tension generated by the compressed grooves locks the pin tightly against the hole wall. This guarantees outstanding resistance to shearing fatigue, continuous high-frequency vibration, and dynamic shocking loads.

  • Ideal for Blind Holes and Reusability: Unlike traditional pins that can score or damage host materials upon removal, our grooved pins allow for clean extraction and reassembly without compromising joint integrity, making them excellent for blind-hole and routine maintenance applications.

  • Perfect for Automated Feeders: With rigid dimensional and tolerance controls, our pins ensure smooth, jam-free feeding in automated assembly systems, substantially increasing your production throughput.

Technical Specification Highlights

  • International Standards & Materials: Fully compliant with DIN 1471 to DIN 1477 (ISO 8739 to ISO 8745) benchmarks. Available in free-cutting steel, high-tensile carbon steel, and premium stainless steel (SUS304 / SUS316).

  • Versatile Groove Configurations: We offer full-length, half-length, center-grooved, and reverse-tapered types (Types A through G) to precisely match functions such as pivoting, hinging, anchoring, or locating.

  • Size Range & Tolerances: Standard diameters range from M1.5 to M12, with customizable lengths based on your blueprints. In-house heat treatment ensures optimal hardness and mechanical consistency.

  • Eco-Friendly Finishes: Options include RoHS and REACH compliant Zinc plating, Zinc-Nickel alloy plating, Dacromet coating, and passivation, delivering over 1,000 hours of corrosion resistance.

Target Applications

  • Automotive & Drivetrain Systems: Gearbox linkages, steering mechanisms, windshield wiper assemblies, and actuator valves.

  • Automation & Heavy Machinery: Robotic arm joints, pneumatic/power tool driveshafts, and precision jig/fixture alignment.

  • Electronics & Precision Hardware: Micro-motor shafts, industrial instrument enclosures, and pivoting hinges in high-end consumer hardware.
