One Pawl Fits All

The pawl is the critical internal component that engages the Tangless® drive notch, and is responsible for holding the insert as it threads into the the STI tapped hole.

The One Pawl Fits All System was designed to eliminate customer confusion by using the same pawl for any Tangless® installation tool of the same thread size. No other manufacturer offers a one pawl system; consequently, users are required to purchase different pawls for different tools of the same thread size. The One Pawl Fits All system reduces inventory management, simplifies ordering, and reduces costs for users of Tangless® inserts and tools.

Features & Benefits

  • The Pawl is made of a high strength aerospace grade steel.
  • The Pawl works with Tangless® installation tools.
  • The One Pawl Fits All System reduce inventory management & simplifies ordering.
