Value Collection JY8962631 Spiral Point Tap 1/2-13 Unc

Product Description

The VALUE COLLECTION JY8962631 is a spiral point plug tap designed for threading 1/2-13 UNC holes in metalworking and maintenance applications. Built from high speed steel (HSS) with a bright uncoated finish, this right-hand tap features 3 flutes and a plug chamfer that pushes chips forward ahead of the cut, making it well suited for through-hole tapping operations. The H11 thread limit designates a slightly oversize tolerance of 0.0050 inches, which accommodates standard plated fasteners and helps prevent galling in tougher materials. Typical users include machinists, millwrights, pipefitters, and maintenance technicians working with ferrous and non-ferrous stock.

This tap is used in production and repair threading where a 1/2-13 UNC internal thread is required. The plug chamfer style makes it a general-purpose choice for through-hole applications across a range of materials. Common install scenarios include threading holes in structural steel, mechanical housings, pipe flanges, and equipment frames in both shop and field environments. The right-hand thread direction matches standard fastener orientation for the vast majority of industrial assemblies.

Key Features

• 1/2-13 UNC thread size for standard unified coarse thread applications
• 3-flute spiral point design pushes chips forward during through-hole tapping
• Plug chamfer provides versatile entry for general-purpose threading
• High speed steel construction offers durability across ferrous and non-ferrous materials
• H11 thread limit with 0.0050-inch oversize accommodates plated fastener clearance
• Bright uncoated finish — suitable for use with standard cutting fluids

Compatibility

Designed as a standard replacement or production tap for any application requiring a 1/2-13 UNC right-hand internal thread in through-hole configurations.

Installation Notes

Spiral point taps are installed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC spindle. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled hole before beginning the threading pass. Apply appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Do not reverse the tap under power without verifying the machine supports it, as this can cause breakage in harder materials.
