Value Collection MSC-04503488 Spiral Point Tap 3-48 Unc

Product Description

The VALUE COLLECTION MSC-04503488 is a spiral point tap designed for cutting right-hand internal threads in through-hole applications. Built from high speed steel with a bright, uncoated finish, this tap produces clean 3-48 UNC threads with two flutes and a plug chamfer that progressively starts the cut and pushes chips forward ahead of the thread. It carries an H2 thread limit and a Class 2B fit, making it suitable for standard tolerance threaded assemblies. The 0.5-inch thread length handles typical fastener depths for the 3-48 size range. Machinists and maintenance technicians reach for this tap for small-diameter threading in steel, aluminum, and similar machinable materials.

This tap is used in machine shop, production, and maintenance-repair-overhaul settings where 3-48 UNC through-hole threads are required. The spiral point geometry is well suited to CNC tapping centers and drill presses where chip evacuation ahead of the tap is needed to prevent chip packing in the flutes. Its compact size and standard right-hand thread direction make it a common choice for instrument work, electronics enclosures, and light mechanical assemblies that use number 3 fasteners.

Key Features

• 3-48 UNC thread size with right-hand thread direction
• High speed steel construction for durability across a range of machinable materials
• Plug chamfer for progressive thread engagement and easy starting in through holes
• Spiral point geometry pushes chips forward, reducing chip-packing in through-hole applications
• H2 thread limit and Class 2B fit for standard tolerance threaded assemblies
• Bright, uncoated finish with no coolant-through feature

Compatibility

Designed as a standard replacement or production spiral point tap for through-hole 3-48 UNC threading operations on manual or CNC tapping equipment.

Installation Notes

Threading operations should be performed by a qualified machinist following applicable shop safety procedures. Secure the workpiece firmly and use appropriate tapping fluid for the material being threaded. Always back the tap out periodically to clear chips and prevent tap breakage, even with spiral point geometry in through holes. Inspect the tap for wear or chipping before each use, as small-diameter taps are susceptible to breakage if excessive force is applied.
