Value Collection JY4946323 Straight Flute Tap 6-32 Unc

Product Description

The VALUE COLLECTION JY4946323 is a straight flute tap designed for cutting 6-32 UNC internal threads in a left-hand direction. Built from high-speed steel with a bright uncoated finish, this tap is suited for general-purpose threading in a range of metalworking and fabrication applications. The plug chamfer provides a gradual lead-in of several threads, making it appropriate for through-hole threading where starting ease and thread accuracy are priorities. With an H3 thread limit and a 2B class of fit, it produces threads within standard tolerance ranges for most fastener assemblies. Overall length is 2 inches, and the 3-flute configuration offers a balance of chip clearance and thread contact in typical ferrous and non-ferrous materials.

This tap is used in machine shop, maintenance, and light manufacturing environments where left-hand threaded fasteners are required. Left-hand taps are specified when a standard right-hand thread would loosen under rotational load, such as in bicycle pedal spindles, certain motor shaft applications, and other assemblies subject to counter-clockwise torque. The plug style and straight flute design make it compatible with both hand tapping and machine tapping operations in through-hole configurations. It is typically installed by machinists, tool and die technicians, and maintenance mechanics working on precision assemblies.

Key Features

• 6-32 UNC thread size with left-hand thread direction for counter-rotation applications
• Plug chamfer for gradual thread engagement in through-hole work
• H3 thread limit with 2B class of fit for standard tolerance threading
• High-speed steel construction provides durability across a range of workpiece materials
• 3-flute design balances chip evacuation with thread form stability
• Bright uncoated finish suitable for use with cutting fluid in most general-purpose applications

Compatibility

Designed as a standard replacement or additional-inventory tap for applications requiring 6-32 UNC left-hand internal threads in through-hole configurations.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench or machine tap holder. Always use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Ensure the tap is aligned perpendicular to the workpiece surface before engagement to avoid tap breakage or cross-threading. Left-hand taps require counter-clockwise rotation to cut threads — confirm thread direction requirements before use.
