Value Collection MSC-04476461 Straight Flute Tap

Product Description

The VALUE COLLECTION MSC-04476461 is a straight flute tap designed for cutting 11/16-16 UNS internal threads in a variety of workpiece materials. Manufactured from high-speed steel with a bright uncoated finish, this tap delivers reliable thread-cutting performance in general machining applications. It features a plug chamfer, which provides a gradual lead-in suitable for through-hole and deeper blind-hole threading. With 4 flutes and a right-hand thread configuration, it is well suited for use in manual tapping operations and CNC machining centers where straight flute geometry is appropriate for the material being threaded.

This tap is used in machine shops, maintenance facilities, and production environments where UNS threads are required. The plug chamfer style makes it a versatile choice for through-holes and blind holes with adequate clearance. It is appropriate for threading softer metals such as aluminum, mild steel, and similar machinable materials where chip evacuation through the flutes is not a limiting factor. Machinists and toolroom technicians performing repair, fabrication, or production threading operations will find this tap a practical addition to standard tap-and-die tooling sets.

Key Features

• 11/16-16 UNS thread size for non-standard unified thread applications
• Plug chamfer for gradual lead-in suited to through-holes and blind holes with clearance
• High-speed steel construction for durability across a range of machinable materials
• 4 straight flutes with right-hand thread direction
• Bright uncoated finish suitable for general-purpose threading
• H3 thread limit for standard tolerance fits

Compatibility

Designed as an OEM-style replacement or standard tooling option for machine shop and maintenance applications requiring 11/16-16 UNS internal threads with a plug chamfer straight flute tap.

Installation Notes

This tap should be installed in a tap holder, tapping head, or rigid machine spindle appropriate for the shank size before use. Always ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap-drill diameter for the 11/16-16 UNS thread before tapping. Apply appropriate cutting fluid to reduce heat and tool wear during the threading operation. Follow established shop safety practices and inspect the tap for wear or damage before each use to avoid thread damage or tool breakage.
