Slotted & Coiled Spring Pins

Slotted & Coiled Spring or hollow pins are economical, universally used shear-type fasteners that are self-locking. They’re manufactured to an oversize dimension so that when the pin is inserted into a hole, radial forces are exerted that hold the spring pin in place.

• Common uses include dowels, spacers, stop pins and hinge pins in thousands of demanding, non-precision industrial applications
• Wide range of standard sizes
• Standard zinc or light oil finish – other finishes also available
• Made by progressive roll forming flat strips of carbon steel or heat-treatable
  420 stainless steel
• Style Choices:
  Slotted: Conventional & Type A Notched;
  Coiled: Light Duty, Standard Duty & Heavy Duty

Description

Tubular slotted spring pins are manufactured by progressive roll forming flat strips of high carbon steel or heat treatable 420 stainless steel. After forming, the pins are deburred to remove sharp edges, then heat treated to a spring temper. High-carbon (1070-1095) steel spring pins are hardened to Rc 46-53 and 420 stainless steel spring pins are hardened to Rc 43-52.

Function

Spring pins are manufactured to an oversize dimension so that when the pin is inserted into a hole, radial forces are generated against the hole wall holding the spring pin securely in place.
