Product Description
The High Strength Multi-Function Integration GB/T 879.4 Heavy Duty Parallel Spring Straight Coiled Pin is a coiled spring pin manufactured to GB/T 879.4, with listing indicating compatibility references to DIN, ANSI, GB, JIS, GOST, and BSW standards. It is described as high strength and high tensile, with a blank head style and connection category “Pins for Autos.” The straight coiled construction is intended for parallel spring applications; buyers should confirm dimensional tolerances, chamfer, and material grade directly with the supplier for critical joint design.
The finish is yellow zinc plated. Transport packaging is plastic bag + carton box + pallet, with a package size of 20×10×10 cm and gross weight 5.000 kg. Reported delivery time is 7–15 days from supplier. The name references multi-function integration, which the supplier applies to anti-loosening, locking, and vibration resistance.
Applications
The supplier lists connection type “Pins for Autos,” making the SKU relevant for automotive assemblies that require vibration-resistant pin fastening. Product categories also include lifting equipment and lifting table components, where parallel spring pins may serve in pivot or locating roles. Confirmation of load rating and material test reports is recommended before use in safety-critical lifting applications.
