Value Collection MSC-04917183 Straight Flute Tap 3/4-16 Unf

Product Description

The VALUE COLLECTION MSC-04917183 is a straight flute tap designed for cutting 3/4-16 UNF internal threads in a left-hand direction. Built from high-speed steel with a bright uncoated finish, it delivers reliable cutting performance across a range of metalworking applications. The taper chamfer eases entry into the workpiece and distributes cutting load across the lead threads. With an H3 thread limit and a 3B class of fit, this tap produces threads within the tolerance range required for standard fastener assemblies. It is suited for use in manual tapping operations or low-speed machine tapping setups where left-hand thread creation is required.

This tap is appropriate for trade and industrial machining environments where left-hand threaded holes are needed, such as in mechanical assemblies where counter-rotation would loosen a right-hand thread. The 2-inch thread length accommodates through-hole and deeper blind-hole applications. With 4 flutes and a taper chamfer entry, it works in ferrous and non-ferrous materials where straight flute geometry is suitable. Machinists, tool-and-die workers, and maintenance technicians working in manufacturing, repair, or fabrication settings are the primary users of this tool.

Key Features

• Left-hand thread direction for counter-rotation fastener applications
• Taper chamfer distributes cutting load and guides tap entry
• H3 thread limit with 3B class of fit for standard tolerance assemblies
• High-speed steel construction for durability across ferrous and non-ferrous materials
• 4 straight flutes for chip clearance in through-hole and open-blind applications
• Bright uncoated finish suitable for use with cutting fluids

Compatibility

Designed as a standard replacement or working tap for 3/4-16 UNF left-hand thread applications in manual tap handles, tapping heads, or compatible machine tap holders that accept the appropriate shank size.

Installation Notes

This tap should be installed and operated by qualified machinists or maintenance technicians familiar with threading tools and tapping procedures. Always secure the workpiece and use appropriate cutting fluid to extend tap life and improve thread quality. Ensure the tap holder or wrench is properly aligned with the hole axis before applying torque to prevent tap breakage. Follow applicable shop safety standards when operating tapping equipment.
