Value Collection MSC-04507323 Spiral Point Tap 8-32 Unc

Product Description

The VALUE COLLECTION MSC-04507323 is a spiral point tap designed for cutting internal threads in through-hole applications. It features an 8-32 UNC thread form with a plug chamfer, allowing the tap to start easily and drive chips forward ahead of the cut rather than packing them into the flute. Manufactured from high speed steel (HSS) with a bright, uncoated finish, it delivers solid performance across a wide range of ferrous and non-ferrous materials. The right-hand thread direction and H2 thread limit ensure a 3B class of fit, meeting standard tolerance requirements for most machine screw threading jobs in manufacturing, maintenance, and fabrication environments.

This tap is suited for threading 8-32 UNC holes in through-hole workpieces where chip ejection ahead of the tool is practical. The 2-flute design provides adequate chip clearance and is well matched to hand tapping or low-speed machine tapping in softer materials. With a 0.75-inch thread length, it covers typical fastener depths encountered in light to medium production work and bench repair tasks. Machinists, maintenance technicians, and toolroom professionals are the primary users.

Key Features

• 8-32 UNC thread form with plug chamfer for through-hole threading
• Spiral point geometry drives chips forward, reducing clogging in through holes
• High speed steel construction for durability across common workpiece materials
• H2 thread limit produces a 3B class of fit for standard tolerance assemblies
• Right-hand thread direction, compatible with standard tap wrenches and tapping heads
• Bright uncoated finish — no coating buildup to affect thread tolerance

Compatibility

Designed as a standard replacement or working tap for 8-32 UNC through-hole threading operations using conventional tap holders, T-handle wrenches, or low-speed tapping machines.

Installation Notes

Secure the workpiece firmly before tapping to prevent movement during the operation. Use a cutting fluid or tapping compound appropriate for the workpiece material to extend tap life and improve thread quality. Ensure the tap is started perpendicular to the work surface to avoid cross-threading. Plug chamfer taps require a through hole or sufficient clearance below the thread depth — do not force the tap to the bottom of a blind hole.
