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
