Trisert-3 self-tapping insert from Tappex
Tappex have launched a new range of self-tapping inserts for critical conditions, Trisert-3.
Designed for plastic and metal alloy applications, Trisert-3 is able to withstand critical environmental conditions, such as marine and chemical/food processing, while still retaining excellent wear resistance and strength.
Trisert-3 is available in two grades of Stainless Steel (303 and 316) and in case hardened steel with a zinc nickel, trivalent passivated finish.
Three cutting features provide balanced cutting forces and reduced installation torque.
Trisert-3 is available in two lengths – regular and long – and is based upon the Trisert Reduced Headed design. This provides an increased bearing surface that not only allows higher tightening torques to be applied, but also provides more support to softer mating components. The head diameter is designed to exactly fit the counter bore in the moulded hole, and thus presents a neat flush fit finish, where required.
The new insert can be rapidly and reliably installed using Tappex’s FlexiArm machine, which consists of a pantograph arm with a pneumatic screwdriver attached. It is available with one, two, or three arms to suit most multi-task assembly requirements.
