Value Collection MSC-04503496 Spiral Point Tap 3-48 Unc

Product Description

The VALUE COLLECTION MSC-04503496 is a spiral point tap designed for cutting 3-48 UNC threads in through-hole applications where the chip is pushed forward ahead of the cutting action. Built from high speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance in a range of common work materials. The bottoming chamfer style allows threading close to the bottom of a blind hole when used in sequence after a taper or plug tap. With 2 flutes and a right-hand thread direction, it conforms to H2 thread limit and a 2B class of fit, making it well-suited for standard fastener thread applications.

This tap is used in general machining, maintenance, and repair operations where 3-48 UNC threads are required. The 0.5-inch thread length accommodates typical depth requirements for small fastener work in metal components. It is appropriate for use in manual tapping operations with a tap wrench or in low-speed machine tapping setups. Trades and shops working on small mechanical assemblies, electrical enclosures, or precision components will find this tap a practical fit for standard threading tasks.

Key Features

• Thread size 3-48 UNC for standard unified coarse thread applications
• Bottoming chamfer for threading near the base of blind holes
• High speed steel construction for durability across common work materials
• H2 thread limit with 2B class of fit for standard tolerance threading
• Right-hand thread direction, 2-flute design
• Bright uncoated finish — no special coolant-through requirement

Compatibility

Designed as an OEM-style replacement or standard-use tap for any application requiring 3-48 UNC right-hand threads at a 2B class of fit.

Installation Notes

Installation is performed by machinists or maintenance technicians using a tap wrench or tapping head. Ensure the workpiece is securely fixtured before tapping to prevent tap breakage on this small thread size. Apply appropriate cutting fluid to reduce heat and extend tap life. Follow the tapping sequence — taper or plug tap first, bottoming tap last — when threading blind holes to full depth.
