Value Collection JY4794483 Acme Thread Tap 3/4-6 4 Flute

Product Description

The VALUE COLLECTION JY4794483 is a 3/4-6 Acme thread tap designed for cutting internal Acme-form threads in metalworking and machining applications. It features a plug chamfer, four straight flutes, and a right-hand thread direction with a 2G class of fit, making it suitable for general-purpose Acme thread production where moderate tolerances are required. Constructed from high-speed steel with a bright, uncoated finish, this tap offers reliable cutting performance in ferrous and non-ferrous materials. The thread length measures 4-5/16 inches and the overall length is 7-15/16 inches. This tool is used by machinists, toolmakers, and maintenance professionals working with lead screws, power transmission components, and threaded actuator assemblies.

This tap is intended for use in manual tapping operations or machine tapping setups where 3/4-6 Acme internal threads are required. The plug chamfer style provides a balance between ease of starting and thread-cutting load, making it appropriate for through-hole and deeper blind-hole applications where a starting tap is not needed. It is commonly used in industrial maintenance, job shops, and production environments where Acme-threaded parts such as vise screws, press screws, and linear actuators are fabricated or repaired.

Key Features

• 3/4-6 Acme thread form with a 29-degree thread angle for standard Acme compatibility
• 2G class of fit for general-purpose internal Acme threads
• Plug chamfer style balances starting ease with cutting performance in through and blind holes
• Four straight flutes for efficient chip evacuation and cutting stability
• High-speed steel construction provides durability across a range of workpiece materials
• Bright, uncoated finish — suitable for use with cutting fluids appropriate to the workpiece material

Compatibility

Designed for cutting 3/4-6 Acme internal threads to a 2G class of fit in through-hole and blind-hole configurations on ferrous and non-ferrous metal workpieces.

Installation Notes

This tap should be installed and used by qualified machinists familiar with Acme thread tapping procedures. Secure the tap in a suitable tap holder or machine spindle before use and ensure the workpiece is firmly fixtured. Apply a cutting fluid appropriate to the workpiece material throughout the operation to reduce heat and extend tap life. Follow applicable shop safety standards and do not exceed the recommended cutting speed for the tap material and workpiece combination.
