Straight Flute Hand Tap 3/8"-16 UNC

This Cleveland C54588 straight flute hand tap cuts 3/8"-16 UNC threads with a plug chamfer and four flutes.

Verify Thread Size and Drill Compatibility

Before ordering confirm that the workpiece requires a 3/8"-16 UNC thread and that a 5/16 inch drill is available for the 75 percent thread depth. The tap has a thread limit of H5 and a class of fit rated 2B and 3B. Right hand threading direction must match the application requirements.

High Speed Steel Construction and Plug Chamfer

High speed steel construction provides durability for repeated hand tapping operations. The plug chamfer eases starting in through holes or blind holes with adequate depth. Bright uncoated surfaces allow easy inspection of cutting edges. Four flutes deliver balanced chip clearance during manual use.
