Value Collection MSC-04837647 Straight Flute Tap 8-64 Uns

Product Description

The VALUE COLLECTION MSC-04837647 is a straight flute tap designed for cutting internal threads in a wide range of materials. Built from high-speed steel with a bright, uncoated finish, this plug chamfer tap produces right-hand threads to the 8-64 UNS specification. The H2 thread limit ensures close dimensional tolerance, making it suitable for general-purpose tapping operations in machine shops, maintenance environments, and production settings. Four straight flutes provide efficient chip clearance in through-hole and blind-hole applications. Machinists, tool and die technicians, and maintenance professionals use this tap for threading ferrous and non-ferrous workpieces by hand or with a tapping machine.

This tap is suited for applications requiring 8-64 UNS threads in light-duty to general-purpose materials including mild steel, aluminum, brass, and plastics. The plug chamfer, with its moderate lead-in, makes it appropriate for both through holes and deeper blind holes where a starting or bottoming tap is not required. It is commonly used in manufacturing, repair, and fabrication environments where consistent thread form and fit are critical.

Key Features

• 8-64 UNS thread specification for consistent, standardized thread form
• Plug chamfer provides moderate lead-in suitable for through holes and most blind-hole applications
• High-speed steel construction offers durability across a range of workpiece materials
• Bright, uncoated finish allows easy visual inspection of cutting edges
• H2 thread limit delivers close tolerance for reliable fit with mating fasteners
• Four straight flutes support efficient chip evacuation during tapping operations

Compatibility

Designed as a general-purpose replacement or standard-stock tap for applications requiring 8-64 UNS right-hand internal threads. Confirm thread standard, chamfer type, and thread limit requirements before installation.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or compatible machine spindle. Always ensure the workpiece is properly secured and that the correct pilot hole diameter for 8-64 UNS threads has been drilled before tapping. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Do not force the tap against resistance, as high-speed steel is susceptible to breakage under excessive torque or misalignment.
