FREQUENTLY ASKED QUESTIONS

How often should I be changing my Tri-Con Coiled Pins?

Short Answer: Replace as soon as you see any signs of wear or mushrooming. This can be as frequent as each shot, depending on jobsite conditions. Consult the user manual.

Correct use: Before and after each bore, inspect the coiled pins, and mating components for wear or deformation. Keep all contact surfaces clean, apply light grease where applicable, and replace pins that show wear to maintain smooth rotation and fast tool changes

Technical details: Coiled pins are designed to protect the Tri-Con connection by absorbing wear during operation. They are purposefully a wear-item to protect the integrity of the Tri-Con Connection.

Incorrect use includes: Reusing damaged or worn pins or allowing debris to build up in the connection. Incorrect use can introduce greater risk of poor fit, difficult tool changes, or reduced connection performance.
