Metric Coiled Spring Pins

High quality spring steel and heat treatment for consistent output

Coiled pins are versatile tension pins that can add value to your products.

Vogelsang Coiled Spring Pins begin with a strip of hardened steel that is wrapped in coils, approximately 2.25 times. By virtue of this design, pins are resilient, versatile and maximize the lifespan of the applications to which they are inserted.

Coiled Spring Pins distinguish themselves from other tension pins at assembly, as the direction of the applied load need not be considered. As a Coiled Spring Pin is installed, the coils absorb the compression from the outer wrap to the inner wrap and equally distribute stresses throughout the pin.

Get Specifications:

Pins continue to flex after installation and most importantly, when a load is applied, continuously absorb the load evenly throughout the pin. They offer greater radial contact, decreasing the potential for hole damage. Coiled Pins will provide a minimum of 270° surface contact in the hole.

Coil spring pins absorb shock and vibrations, and will not gouge softer materials. Uniform length and flexibility provides equal stress distribution and controlled radial shock, offering reduced fastener costs.

Metric pins are stocked in 1mm to 16mm in a variety of materials, specifications and finishes. Our engineers are available to help you choose the right pin for your application.

Applications

Coil spring pins are manufactured in three duties. The standard duty (also called medium duty) has adequate characteristics and strength for most applications.

Heavy Duty coil pins offer superior shear strength and are highly recommended for applications where loading and stress factors are elevated.

Light duty coil pins are used in soft materials where strength is not a factor.

Because of their flexible coiled construction, all VFS Coiled Spring Pins absorb shock and vibration without compromise to the pin’s strength. This is especially valuable in Heavy Duty and medium duty applications such as axles, pivots, door handles, door locks, cases, hinge pins, alignment pins, stop pins, circuit breakers, electric motors, pumps, steering columns, and in assembly settings with multiple components.
