Value Collection MSC-04505400 Spiral Point Tap 5-40 Unc Hss

Product Description

The VALUE COLLECTION MSC-04505400 is a spiral point tap designed for cutting internal threads in through-hole applications. It features a 5-40 UNC thread form with a plug chamfer and two flutes, making it suitable for general-purpose tapping in a wide range of materials. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in production and maintenance environments. The right-hand thread direction and H2 thread limit support consistent fits to Class 2B and 3B tolerance standards. Licensed machinists, tool-room technicians, and maintenance mechanics are the primary users.

This tap is intended for through-hole tapping operations where the spiral point geometry pushes chips forward ahead of the cutting edge rather than backing them out. The 5-40 UNC size is common in light-duty fastening applications including instrument panels, electronics enclosures, small mechanical assemblies, and precision fixtures. The 5/8-inch thread length accommodates typical material thicknesses encountered in these applications. It is suited for both manual and machine tapping setups.

Key Features

• 5-40 UNC thread form with right-hand cut for standard through-hole tapping
• Plug chamfer provides gradual thread engagement, suitable for most through-hole work
• Two-flute spiral point design pushes chips forward to keep the cutting zone clear
• H2 thread limit for Class 2B and 3B fit tolerances
• High speed steel construction for general-purpose use across a range of workpiece materials
• Bright, uncoated finish with no coolant-through feature, appropriate for standard cutting fluids applied externally

Compatibility

Designed as an OEM-style replacement or standard tooling addition for applications requiring a 5-40 UNC spiral point plug tap with H2 thread limit and Class 2B or 3B fit.

Installation Notes

This tap should be installed in a tap wrench, tapping head, or CNC spindle with proper alignment to the drilled pilot hole before use. Always use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Ensure the workpiece is securely fixtured before tapping to prevent tap breakage. Follow applicable shop safety procedures and machine guarding requirements when operating tapping equipment.
