WALTON Tap Extensions Style B

Features | Dimensions: Regular Taps    Pipe taps

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.

Inexpensive - Our cost is considerably less than the cost of "special," hard-to-get extra length taps, yet they can be used many times, as they do not wear out like the taps they are used with.
