RECOIL ADVANTAGES

Recoil inserts are the quick and easy method for repairing damaged threads, or creating stronger original threads in alloys and composite materials in original equipment manufacture.

• Create stronger threads in most materials.
  
  
• Made from corrosion resistant stainless steel.
  
  
• Simplifies changeover from unified to metric and vice versa.
  
  
• Interchangeable with other brands of inserts and tooling.
  
  
• Reduces thread wear.
  
  
• Wide temperature tolerance.
  
  

This versatility makes Recoil Inserts suitable for a wide range of applications.

AUTOMOTIVE REPAIRS

Commonly used in automotive machine shops for spark plug and general thread repairs.

MACHINE SHOPS

Recoil thread repair kits help prevent costly machine downtime Range Kits, a multiple size kit format, are widely used in maintenance workshops

OEM

As Recoil creates superior threads with greater holding power in most materials they are widely used in original equipment manufacture such as electronics, automotive, aerospace, plastics, etc.

How RECOIL WORKS

Recoil inserts are made from high quality stainless steel wire, with a diamond shaped cross section, wound to the shape of a spring thread. The insert, which is larger in diameter than the tapped holes is compressed during installation then allowed go spring back, permanently anchoring the insert in the tapped hole.



Because of the larger diameter, the Recoil insert has a greater contact area and is normally stronger the original threads.
