GROOVED PINS

Technifast stock grooved pins with parallel or tapered grooves, to DIN and ISO standards in mild steel or stainless steel A2. Half length / full length taper grooves.  Grooved pins are solid pins with three swaged grooves at 120° pitch along all or part of their length. When the pin is driven into a drilled hole of suitable diameter, the material displaced by the grooving process is forced back, to partially close up the grooves and lock the pin into place.

Standards

 • DIN 1471 (GP1) Similar to ISO 8744 - Full length taper grooves used to fix two or more components together, but with less insertion force than DIN 1473

• DIN 1472 (GP2) Similar to ISO 8745 - Half length taper grooves used where part of the assembly must be a free fit

• DIN 1473 (GP3) Similar to ISO 8740 - Full length parallel grooves used to fix two or more components together with maximum rigidity

• DIN 1474 (GP4) Similar to ISO 8741 - Half length reverse taper grooves used where the ungrooved portion acts as a stop or handle

• DIN 1475 (GP8) Similar to ISO 1842 - Third length centre grooves used on hinges or clevises where the two ends must act as a pivot
