Grooved Pins

SKU: PKC09 Category:

Grooved pins, which feature either parallel or tapered grooves are produced as standard in mild steel or A2 stainless steel, in either half length of full length sizes.

They are solid pins that are commonly used as a connecting element. When the pin is driven into a drilled hole, the material displaced by the grooving of the pins is forced back to partially close up the grooves and lock the pin into place.

They host a number of advantages, including the fact that they do not need a precision reamed hole, and the fact that they can be grooved on only part of the length.

Technical drawings are available to view below.

Available from stock at Fastenright, with specials available to order.
