Coil Polylock

Coils (threaded inserts) create high-strength joints in low-strength metallic materials and have been proven in practice for decades. HONSEL coils threaded inserts are available in a range of variants and are characterised by high wear resistance, low thread friction in close tolerances, high surface quality and outstanding corrosion and heat resistance.


  • Aditional polygon-shaped coil - screw gripping area
  • Good friction connection - through this, unscrewing is prevented
  • Cost reduction - possibility of managing without additional screw locking devices
