Value Collection MSC-04476214 Tap Set 5/8-18 Unf Hss

Product Description

The VALUE COLLECTION MSC-04476214 is a 3-piece tap set designed to cut 5/8-18 UNF internal threads in ferrous and non-ferrous materials. Each tap is machined from high-speed steel (HSS) with a bright, uncoated finish and features 4 flutes for efficient chip evacuation during threading operations. The set measures 3-13/16 inches overall length with a 1-13/16 inch thread length, and cuts right-hand threads to a H3 thread limit. It is suited for job-shop machining, maintenance and repair operations, and production threading tasks where a full tap progression is needed.

This tap set is appropriate for threading operations in machine shops, manufacturing facilities, and maintenance environments. The 5/8-18 UNF thread form is commonly encountered in precision mechanical assemblies, hydraulic fittings, and fastener applications requiring a fine-pitch thread. The 4-flute geometry and HSS construction handle both hand-tapping and machine-tapping setups in mild steel, aluminum, brass, and similar materials.

Key Features

• High-speed steel construction provides durability and resistance to heat generated during threading
• 4-flute design promotes efficient chip removal and clean thread formation
• Bright, uncoated finish suitable for general-purpose threading in a range of materials
• H3 thread limit for consistent fit and dimensional accuracy on 5/8-18 UNF threads
• Right-hand thread direction for standard threading applications
• 3-piece set provides taper, plug, and bottoming progression for through-hole and blind-hole work

Compatibility

Designed for cutting 5/8-18 UNF right-hand internal threads. Suitable for use in standard hand-tapping handles and compatible machine-tapping chucks or CNC toolholders sized for the 5/8-18 shank.

Installation Notes

Threading operations should be performed by a qualified machinist or trained technician familiar with tap selection and cutting fluid application. Always use an appropriate cutting or tapping fluid matched to the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before starting and align the tap perpendicular to the drilled hole to avoid tap breakage. Follow the taper-to-plug-to-bottoming sequence when threading blind holes.
