Description

Oversized taps are taps that are typically +0.003''/+0.005'' larger than the standard pitch diameter. An H7 thread limit tap is +0.003'' oversize from the basic pitch diameter while the H11 tap is +0.005'' oversize. Oversize taps are typically used for threading holes that will be subsequently plated or heat treated after tapping. Guhring offers TiN coated plug and bottoming style oversize taps as stocked standards.
