pronged T-Nuts

Rivet T-Nuts 

Rivet T-Nuts are designed to be machine-inserted and are manufactured through. They feature a robust heavy flange and a large head to ensure strength and pull-through resistance. The result is an efficient fast, deep and straight insertion of the Tee Nut. This contributes to final product quality and production efficiency. 

When inserted, the unthreaded portion of the barrel is riveted over to achieve maximum push-out resistance, eliminating the need for over-stapling. The riveted area of the T-Nut creates an effective lead-in for the bolt thread for easier assembly. This lead-in feature minimises cross-threading problems. This feature is particularly beneficial when customers need to attach castors after delivery. 

Once inserted, the unthreaded rivet portion of the T-Nut provides a good lead for the screw or bolt, enabling easier assembly and eliminating the requirement for over-stapling. 

  • Strong 
  • Good pull-through resistance 
  • Fast, deep, straight insertion 
  • Better final product quality 
  • Production efficiency
  • Good lead for the screw or bolt 
  • No over-stapling required
