Extension Tap: 3/8-16, H6, Bright/Uncoated, High Speed Steel, Thread Forming MPN:13526-010

Extension taps are designed to form threads on blind or restricted holes, allowing threads to be created at the back of a hole instead of the front like other taps. This extension tap features an H6 thread tolerance and is manufactured from high-speed steel for strength and durability when cutting through difficult materials like stainless steel or hardened metals. With a 3/8 -16 thread size, this tool can be used in numerous applications where stronger, more precise threads need to be created on the underside of a workpiece in aerospace, automotive or mechanical engineering industries among others where professional precision machining services are required by skilled craftspeople and engineers.
