Value Collection MSC-04476149 Tap Set 5/8-11 Unc Hss

Product Description

The VALUE COLLECTION MSC-04476149 is a 3-piece tap set designed to cut internal 5/8-11 UNC threads in ferrous and non-ferrous materials. Built from high-speed steel (HSS) with a bright uncoated finish, this set delivers reliable cutting performance across a range of threading applications. The taps measure 3-13/16 inches overall length with a thread length of 1-13/16 inches. A 4-flute geometry provides chip clearance and stable thread form during cutting. The H3 thread limit designates a tolerance class suited for use with standard fasteners and threaded assemblies. This set is installed by machinists, maintenance technicians, pipefitters, and general trade professionals performing threading work on metal components.

This tap set is suited for threading operations in machine shops, maintenance and repair environments, and fabrication settings requiring 5/8-11 UNC internal threads. The right-hand thread direction makes it compatible with standard UNC fastener assemblies. The 3-piece configuration typically includes taper, plug, and bottoming taps, allowing the user to start, continue, and finish threads in through-holes and blind holes alike. This set is appropriate for both bench use with a tap wrench and machine tapping operations.

Key Features

• High-speed steel construction resists wear during threading of steel, iron, and aluminum
• 4-flute design provides chip clearance and maintains thread form accuracy
• H3 thread limit tolerance suits standard UNC fastener fit classes
• Bright uncoated finish allows visual inspection of cutting edges
• Right-hand thread direction for standard UNC fastener compatibility
• 3-piece set covers taper, plug, and bottoming tap profiles for through and blind holes

Compatibility

Designed for cutting 5/8-11 UNC internal threads per Unified National Coarse thread standards. Compatible with standard tap wrenches and machine tapping setups accepting this thread size and tap geometry.

Installation Notes

Threading operations should be performed by a qualified machinist or maintenance technician using appropriate tapping fluid or cutting oil to extend tap life and improve thread quality. Secure the workpiece firmly before beginning; use the correct tap drill size for 5/8-11 UNC as specified in standard machining references. When tapping by hand, back off a half turn periodically to break chips and prevent tap breakage. Never force a tap against resistance — damaged or broken taps in a workpiece are difficult to remove and can render the part unusable.
