Value Collection MSC-04530218 Spiral Point Tap 1/4-20 Unc

Product Description

The VALUE COLLECTION MSC-04530218 is a spiral point tap designed for threading 1/4-20 UNC holes in a wide range of materials. Spiral point taps push chips forward ahead of the cutting action, making them well suited for through-hole threading applications where chip evacuation is critical. This tap features a plug chamfer, 3 flutes, and is manufactured from high speed steel (HSS) with a bright, uncoated finish. The H2 thread limit provides close tolerance control for general-purpose threading work. It is a standard right-hand tap used by machinists, maintenance technicians, and fabricators in production and repair environments.

This tap is intended for through-hole threading operations in metals and other machinable materials. The plug chamfer style requires a started hole and is the most common choice for production threading where a power feed or hand tapping is used. The 1 inch thread length provides adequate engagement for standard fastener depths in the 1/4-20 UNC thread form. Typical applications include machine assembly, fixture fabrication, and field repair work where 1/4-20 UNC threaded holes are required.

Key Features

• Spiral point design pushes chips forward, ideal for through-hole threading
• 1/4-20 UNC thread form for standard fractional fastener applications
• Plug chamfer style suits both hand and machine tapping
• High speed steel construction provides durability across common machinable materials
• H2 thread limit for close general-purpose tolerance control
• Bright uncoated finish, right-hand cut, no coolant-through requirement

Compatibility

Designed as a standard replacement or production tap for any application requiring a 1/4-20 UNC, 3-flute, plug chamfer spiral point tap in H2 thread limit.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench, tapping head, or CNC tapping cycle. Always drill the correct tap drill size for 1/4-20 UNC before tapping and ensure the workpiece is securely fixtured. Apply appropriate cutting fluid to extend tool life and improve thread quality. Do not force a tap that has seized — back off to break the chip before continuing.
