Latest blog post on Tappex self threading thread inserts for metal, plastics, composite materials and wood
Tappex® has acquired, since it was established in 1957, a comprehensive knowledge of the application requirements of threaded inserts fastening across global industries. In recent years, in particular, our range of self-threading inserts have been progressively developed to include new products necessary to meet the demands of the metals processing industries and more critical customer applications.
Such critical applications include: castings, machined & sometimes fabricated parts produced from light metal alloys i.e. aluminium, zinc & magnesium. Our inserts have been extensively trialled and supplied to customers around the world, on land, sea, air & even in space. Our inserts are of the self tapping type installed into either cast or pilot drilled holes to suit customer’s product manufacturing processes.
Self Tapping Plated Steel or Stainless Steel Insert. Self Threading / Post mould installation
The Tappex Trisert-3 has three cutting features to provide a balanced cutting action and reduced installation torque. The Trisert-3 is suited for critical applications and is available in two lengths, regular and long, and is based upon the Trisert Reduced Headed design.
Threaded Screw Inserts
The use of self-tapping thread inserts has significant advantages over pre-tapped holes, moulded-in inserts and wire thread inserts. They eliminate close tolerance holes required for tapping directly into the base material, damaged tools and low productivity resulting from moulded-in inserts and the time consuming process of placing wire thread inserts into pre-tapped holes. The trisert 3 range offers engineers an easy to fit alternative to traditional thread repair products such as helicoils.
