High-strength fastening in to super-lightweight materials

Weight reduction is a universal design imperative. This has created a demand for fastening solutions that allow materials such as foams and honeycombs to be used with greater flexibility, more extensively and with seamless integration.


EJOT TSSD®  for honeycomb webs and composite panels

The EJOT TSSD® product range is a rapid and outstandingly strong thermal adhesive fastening system. It is designed to offer significant assembly time and performance advantages when used with a wide range of lightweight honeycomb and composite materials across many industry sectors.
Launched in the UK at the Automechanika exhibition in Birmingham in 2017, the TSSD® system is game-changing technology that delivers key benefits that include:
  • A lightweight bonding boss offering outstanding strength and versatility
  • Variants suited to many applications 
  • Rapid fixing process requires no pre-drilling or other surface preparation
  • Can be automated for repeatability to customer specification
  • Pre-drilling is not required
