Value Collection MSC-04475141 Straight Flute Tap 9/16-12

Product Description

The VALUE COLLECTION MSC-04475141 is a straight flute tap designed for cutting 9/16-12 UNC internal threads in a wide range of materials. Built from high-speed steel with a bright, uncoated finish, this tap features four flutes and a taper chamfer that guides the tool into the workpiece gradually, reducing the torque needed to start the cut. It carries an H3 thread limit, making it suitable for standard tolerance threading applications. Overall length is 3-19/32 inches, with a thread length of 1-21/32 inches. The tap weighs 0.15 pounds. Machinists, tool and die workers, and maintenance technicians use this type of tap for hand tapping and machine tapping operations.

This tap is intended for right-hand threading in through-hole or blind-hole applications where a taper chamfer style is appropriate. The taper chamfer distributes cutting load across several leading threads, making it a preferred choice for starting threads in harder materials or when tapping by hand. It is commonly used in general manufacturing, maintenance and repair operations, and fabrication shops where 9/16-12 UNC fastener threads are required.

Key Features

• Thread size 9/16-12 UNC with right-hand thread direction
• Taper chamfer for gradual thread engagement and easier starting
• Four straight flutes for chip clearance in through-hole and short blind-hole applications
• High-speed steel construction for durability across a range of workpiece materials
• H3 thread limit for standard tolerance threading
• Bright, uncoated finish suitable for general-purpose use

Compatibility

Designed as a general-purpose replacement or supplementary tap for any application requiring a 9/16-12 UNC straight flute taper tap in high-speed steel.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench or tapping machine. Always secure the workpiece firmly before tapping and use an appropriate cutting fluid to extend tool life and improve thread quality. Ensure the tap is aligned perpendicular to the workpiece surface before beginning. Do not force the tap if resistance increases sharply, as this may indicate chip buildup or an undersized pilot hole.
