Value Collection JY4763207 Spiral Point Tap 7/16-20 Unf

Product Description

The VALUE COLLECTION JY4763207 is a spiral point plug tap designed for cutting right-hand internal threads in through-hole applications. Built from high speed steel (HSS) with a bright, uncoated finish, it produces a 7/16-20 UNF thread profile using 3 flutes to drive chips forward and clear the cutting zone. The H11 thread limit designates this tap as oversize by 0.0050 inches, which compensates for thread springback in materials that tend to close after tapping. Coolant-through capability is not included. This tap is suited for machine tapping and hand tapping operations in production and maintenance environments.

This tap is used in applications requiring unified fine thread (UNF) fastener engagement at the 7/16-20 pitch, common in automotive, aerospace, and general metalworking assemblies. The plug chamfer style — typically 3 to 5 lead threads — makes it appropriate for through-hole tapping where the tap can pass completely through the workpiece. It is used by machinists, tool-and-die workers, and maintenance technicians working with steel, aluminum, and similar machinable materials.

Key Features

• 7/16-20 UNF right-hand thread form for standard fine-pitch fastener engagement
• 3-flute spiral point geometry pushes chips ahead of the tap to keep the cutting zone clear
• Plug chamfer provides a gradual lead-in suited for through-hole tapping
• H11 thread limit with 0.0050-inch oversize allowance compensates for material springback
• High speed steel construction offers good wear resistance across a range of machinable metals
• Bright uncoated finish — compatible with most cutting fluids without coating compatibility concerns

Compatibility

Designed as an OEM-style replacement or standard production tap for through-hole applications requiring a 7/16-20 UNF right-hand thread in metalworking and machining operations.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with tapping operations and cutting fluid selection. Secure the workpiece firmly before tapping and use appropriate cutting fluid for the material being threaded. Align the tap square to the hole to prevent tap breakage and thread distortion. Inspect the tap for wear or chipping before each use, and never force a tap that has stopped turning freely.
