Spiral Point Tap 3/8-16 UNC
This ZORO SELECT spiral point tap cuts 3/8 inch UNC threads with a 16 threads-per-inch pitch. It is made from high speed steel with a bright uncoated finish. The right-hand tool has three flutes and an H3 thread limit for a 2B class of fit.
Verify tap drill size and material suitability
Check that your tap drill matches the 3/8-16 UNC specification before starting. Confirm the workpiece material is compatible with high speed steel cutting. Ensure your tapping equipment can accommodate the 2 15/16 inch overall length and 1 1/4 inch thread length.
Suited for through-hole threading in general
This tap suits machinists producing internal threads in through-holes where chip evacuation ahead of the tool is preferred. It is not for blind holes requiring bottoming taps, nor for left-hand thread applications. Buyers needing coated tools for abrasive alloys or different thread standards should look elsewhere.

Questions about this item
Does the tap come with a handle or wrench, or must I buy one separately?
The tap is supplied on its own; a compatible tap wrench or T-handle must be purchased separately to drive it.
Which thread limit should I choose for a standard 3/8-16 UNC hole?
The H3 limit matches a 2B class of fit, which is the normal choice for general-purpose 3/8-16 UNC threading.
How deep can the 1 1/4 in thread length cut in a single pass?
The 1 1/4 in thread length sets the maximum depth of full-form threads produced in one continuous cut.
