Value Collection MSC-04516332 Spiral Point Tap 6-32 Unc

Product Description

The VALUE COLLECTION MSC-04516332 is a spiral point tap designed for cutting 6-32 UNC threads in through-hole and open-ended applications. Built from high speed steel (HSS) with a bright, uncoated finish, it features a bottoming chamfer profile and a 2-flute spiral point geometry that pushes chips forward ahead of the cutting zone, keeping the flutes clear during threading. The H3 thread limit holds tolerance for a 2B class of fit, making it a reliable choice for standard machine screw thread production in ferrous and non-ferrous materials. Overall length is 2 inches, with a thread length of 11/16 inches.

This tap is suited for production and repair threading operations where 6-32 UNC fastener clearances are required. The bottoming chamfer allows threading closer to the bottom of a blind hole than a plug or taper tap, but it is most effective in through-holes or pre-threaded setups where chips can exit freely. Common applications include light-gauge sheet metal, electronic enclosures, fixture plates, and general machine shop work. It is used by machinists, tool-and-die makers, and maintenance technicians across a range of industries.

Key Features

• 6-32 UNC thread form with H3 thread limit for consistent 2B class of fit tolerances
• Spiral point geometry pushes chips forward, reducing clogging in through-hole operations
• Bottoming chamfer allows threading close to the base of a hole
• High speed steel construction provides good wear resistance across a range of workpiece materials
• Bright, uncoated finish — compatible with most cutting fluids without coating interaction
• Right-hand thread direction for standard tapping operations

Compatibility

Designed as an OEM-style replacement or standard tooling addition for any application requiring 6-32 UNC right-hand internal threads, compatible with standard tap wrenches and tapping heads accepting this shank size.

Installation Notes

Threading operations should be performed by a qualified machinist or technician using a properly sized tap wrench, tapping head, or CNC tapping attachment. Always use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Ensure the tap is driven square to the workpiece to avoid thread angle error or tap breakage. Back the tap off periodically to break chips when working in deeper holes, even with spiral point geometry.
