Value Collection MSC-04475208 Straight Flute Tap 9/16-18 Unf

Product Description

The VALUE COLLECTION MSC-04475208 is a straight flute tap designed for cutting 9/16-18 UNF internal threads in a variety of workpiece materials. It features a taper chamfer, which distributes the cutting load gradually across the lead threads, making it well suited for through-hole tapping operations. Constructed from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance across general-purpose threading applications. With a thread length of 1-21/32 inches and an overall length of 3-19/32 inches, it fits standard tap handles and machine tapping setups used in machining and maintenance environments.

This tap is appropriate for use in machine shops, maintenance and repair operations, and production environments where UNF threads are required. The 9/16-18 UNF specification is commonly found in precision fastener applications, hydraulic fittings, and mechanical assemblies that demand finer thread pitch than UNC equivalents. The taper chamfer makes this tap a practical choice for hand tapping or machine tapping of through holes in ferrous and non-ferrous metals.

Key Features

• 9/16-18 UNF thread specification for fine-thread applications
• Taper chamfer distributes cutting load for easier thread entry in through holes
• 4-flute straight flute geometry for chip clearance and thread accuracy
• High-speed steel construction for durability across general-purpose materials
• Bright, uncoated finish suitable for use with cutting fluids
• H3 thread limit for controlled tolerance fit
• Right-hand thread direction, standard orientation

Compatibility

Designed as a general-purpose replacement or new-installation tap for applications requiring 9/16-18 UNF right-hand internal threads in through-hole configurations.

Installation Notes

Taps should be installed and operated by machinists or maintenance technicians familiar with threading tools and proper speeds and feeds. Always secure the workpiece firmly before tapping, and use an appropriate cutting fluid to reduce heat and extend tool life. Align the tap perpendicular to the workpiece surface to avoid thread misalignment or tap breakage. Back the tap out periodically to clear chips when tapping by hand.
