Value Collection JY4836490 Straight Flute Tap 6-48 Uns

Product Description

The VALUE COLLECTION JY4836490 is a straight flute bottoming tap designed for cutting 6-48 UNS internal threads in through-holes and blind holes where full thread depth close to the bottom is required. Constructed from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in a wide range of ferrous and non-ferrous materials. It features 3 straight flutes, a right-hand thread direction, and an H2 thread limit for controlled tolerance. Overall length is 2 inches. Machinists, tool-and-die workers, and maintenance technicians use this tap for precision thread repair and fabrication work.

This bottoming tap is suited for applications where a standard taper or plug tap has already started the thread and a full-depth thread at the bottom of a blind hole is needed. It is commonly used in general machining, maintenance and repair operations, and toolroom environments. The 6-48 UNS thread size makes it appropriate for small fastener applications in instrument, electronics, and light mechanical assemblies where a unified national special thread form is specified.

Key Features

• Bottoming chamfer allows threading to the base of blind holes
• High-speed steel construction provides strength and wear resistance across common shop materials
• 3 straight flutes for chip clearance in through-hole and shallow blind-hole applications
• H2 thread limit ensures consistent tolerance control for standard fit classes
• Right-hand thread direction for standard threading operations
• Bright, uncoated finish suitable for use with cutting fluids across a range of materials

Compatibility

Designed as an OEM-style replacement or direct-use tap for applications requiring a 6-48 UNS internal thread form with a bottoming chamfer profile.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or machine spindle appropriate for the thread size. Always use a cutting fluid compatible with the workpiece material to reduce friction and extend tap life. Ensure the tap is started straight and aligned with the drilled hole before applying torque to prevent tap breakage. Do not force the tap past resistance, especially in blind holes, as the bottoming geometry leaves minimal chip clearance.
