Helical grooved pins maintain assembly integrity

Standard inch and metric helical grooved solid pins are designed for high-shear applications where a grooved pin is installed into a hardened hole.

Spirol Industries, the leading supplier of engineered fastener solutions, has introduced a line of standard inch and metric helical grooved solid pins for high-shear applications where a grooved pin is installed into a hardened hole.

With standard grooved pins, the high peaks tend to shear off during installation, causing retention problems and field failures.

These new helical grooved pins solve this assembly challenge.

Spirol's helical grooved pins utilise a unique groove configuration, making them the ideal solid pin for installation in harder host materials.

Wide, low-profiled peaks spiral about the body of the pin, allowing the pin to maintain its integrity when installed into a hardened hole.

These helical grooves provide low and consistent installation forces, compared to common solid pins.

Spirol offers these grooved pins in three styles for specific applications: Series GP200 Full Length Groove; Series GP210 Half Length Centered Groove; and Series GP220 Half Length Offset Groove.

Standard materials for helical grooved pins include low carbon steel and 300 Series austenitic stainless steel.

Standard finishes include plain oiled, zinc plated, phosphate coated, and passivated.

Standard inch diameters are 1/16" to 1/4" with lengths ranging from 1/4in to 2-1/4in.

Standard metric diameters are 1.5mm to 6mm with lengths ranging from 6mm to 55mm.

Other materials, finishes, diameters, and lengths are available on request.

Spirol's Helical Grooved Pins are cost-effective solutions for high-shear pinning applications traditionally reserved for conventional grooved pins and dowels.
