A new line of grooved pins from Spirol International Corp. targets high-shear pinning applications in which the pin must be installed in a hardened hole. These patent-pending pins feature a low-profile helical groove configuration designed to prevent the peaks of the grooves from shearing off during installation, causing retention problems. Spirol offers the helical grooved pins in full-length, half-length-centered, and half-length-offset groove styles. Available in standard inch and metric sizes, the pins come in a variety of standard and custom materials, including low-carbon steel and 300 Series stainless.
