Value Collection JY4845335 Straight Flute Tap 9/16-32 Uns

Product Description

The VALUE COLLECTION JY4845335 is a straight flute bottoming tap designed for cutting 9/16-32 UNS internal threads in pre-drilled holes. Built from high-speed steel with a bright/uncoated finish, this tap delivers reliable thread-forming performance in a range of metals and materials. The bottoming chamfer allows threading close to the bottom of blind holes, making it well suited for applications where full thread depth near the hole base is required. With 4 flutes and an H3 thread limit, the JY4845335 holds tight tolerances for a 3B class of fit. Machinists and tool and die technicians are the primary users.

This tap is used in machine shops, maintenance facilities, and production environments where UNS unified special threads are called for. The 9/16-32 thread designation indicates a fine-pitch unified special thread not found in standard UNC or UNF series, making this a purpose-specific tool for specialty fastener applications in precision assemblies. Right-hand thread direction aligns with standard installation tooling. The 3-19/32 inch overall length is compatible with standard tap handles and machine tool holders.

Key Features

• Bottoming chamfer for threading to the bottom of blind holes
• 4-flute design provides balanced cutting and chip support
• High-speed steel construction for durability across a range of work materials
• H3 thread limit maintains consistent 3B class of fit tolerances
• Bright/uncoated finish — no coating variability affecting thread dimensions
• Right-hand thread direction for use with standard tapping equipment

Compatibility

Designed for cutting 9/16-32 UNS right-hand internal threads in applications requiring a 3B class of fit. Compatible with standard tap handles and machine tapping equipment that accept taps of 3-19/32 inch overall length.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using appropriate tap handles or machine tool holders. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill diameter for 9/16-32 UNS threads before tapping. Use cutting fluid appropriate for the work material to extend tap life and improve thread quality. Inspect the tap for wear or damage before each use, and do not force a tap that shows resistance, as breakage in the hole may result in costly recovery work.
