Value Collection JY4793121 Acme Thread Tap 7/16-12 2G 4 Flute

Product Description

The VALUE COLLECTION JY4793121 is a 7/16-12 Acme thread tap designed to cut right-hand internal Acme threads to a 2G class of fit. Acme threads are a trapezoidal thread form with a 29-degree included angle, commonly used in power-transmission applications such as lead screws, vises, and linear actuators. This tap features 4 straight flutes and a plug chamfer, making it suited for through-hole tapping where the tap can pass completely through the workpiece. Manufactured from high-speed steel with a bright, uncoated finish, it delivers reliable performance in a range of ferrous and non-ferrous materials.

This tap is used in machine shops, toolrooms, and maintenance environments where Acme-threaded components require new thread cutting or rethreading. The plug chamfer style distributes the cutting load across several leading threads, making it appropriate for through-hole applications in production or repair work. The 4-flute straight-flute configuration provides chip clearance during cutting. Installation is typically performed on a manual or CNC milling machine, drill press, or tapping arm by a machinist or skilled tradesperson.

Compatibility

Designed as a general-purpose Acme thread tap for cutting 7/16-12 right-hand internal Acme threads in through-hole applications across standard machine shop and maintenance toolroom use.

Installation Notes

This tap should be installed and operated by a qualified machinist using appropriate tapping fluid for the workpiece material. Secure the workpiece and ensure proper alignment before beginning the tapping operation to avoid tap breakage. Power down or disengage the drive before changing or inspecting the tap. Follow shop safety protocols and applicable tooling manufacturer guidelines when selecting speeds and feeds.
