Value Collection MSC-04424503 Straight Flute Tap 4-48 Unf

Product Description

The VALUE COLLECTION MSC-04424503 is a straight flute tap designed for cutting 4-48 UNF internal threads in a wide range of materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable thread formation in light production and maintenance applications. The taper chamfer eases entry into the hole and distributes cutting load across several leading threads. With 3 flutes and an H2 thread limit, this tap holds tight tolerances for a 2B class of fit, making it suitable for standard fastener thread requirements in metal fabrication, repair, and assembly work.

This tap is used in machine shop, tool room, and field maintenance settings where fine unified threads in small-diameter holes are required. The 4-48 UNF specification is common in precision assemblies, instrumentation, and small mechanical components where a fine thread pitch provides greater tensile strength and finer adjustment than coarse-thread alternatives. Right-hand cutting direction matches standard drill press, tapping arm, and hand-tapping operations. It is sized for use with the appropriate 4-48 UNF tap drill and standard tap wrench or machine tap holder.

Key Features

• 4-48 UNF thread form with H2 thread limit for consistent 2B class-of-fit tolerances
• Taper chamfer distributes cutting load for easier starting and reduced breakage risk
• High-speed steel construction provides hardness and wear resistance for threading steel, aluminum, and similar materials
• 3-flute design balances chip clearance and tool strength in small-diameter taps
• Bright uncoated finish suitable for general-purpose threading without coolant-through requirement
• Right-hand cut, standard direction for use with conventional tapping equipment

Compatibility

Designed as a standard replacement or stock tap for any application requiring a 4-48 UNF taper chamfer straight flute tap in HSS with a 2B class of fit.

Installation Notes

Machinist or maintenance technician installation recommended. Always drill the correct tap drill size for 4-48 UNF before tapping to avoid tool breakage. Ensure the workpiece is securely clamped and the tap is properly aligned perpendicular to the hole before applying cutting pressure. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish.
