Walton Type B Tap Extensions
For machine and hand tapping | |
Features: Easy Access - These Tap Extensions provide accurate, easy access into hard-to-reach tapping locations. Smaller socket end O.D. permits extension to pass through a standard liner bushing. Quality Tool - Made of alloy steel to close tolerances and carefully heat-treated for strength and durability, both the square and round sockets conform to size standards of leading tap manufacturers. Tap Held Securely - Each extension is designed for a specific tap size. The tap, supported by the close-fitting deep socket of the extension, is held firmly in position by two socket set screws bearing 90° apart on the square of the tap. |
