Value Collection JY4794640 Acme Thread Tap 1-5 2G 4 Flute

Product Description

The VALUE COLLECTION JY4794640 is a straight-flute Acme thread tap designed to cut 1-5 Acme internal threads in a right-hand direction. With a 29-degree thread angle and a 2G class of fit, this tap produces threads suited for power-transmission and motion-control applications where controlled clearance is required. The plug chamfer allows it to start in through-holes or deeper blind holes with adequate clearance. At 10.125 inches overall length with a 5.25-inch thread length, it has the reach for deeper workpieces. Manufactured from high-speed steel with a bright, uncoated finish, this 4-flute tool is intended for use by machinists and toolroom professionals in production or maintenance settings.

This tap is suited for cutting Acme threads in ferrous and non-ferrous metals in applications such as lead screws, jacks, vises, and other linear-motion assemblies. The tandem-compatible design and straight flute geometry support use in both manual and machine tapping operations. The 2G tolerance class makes it appropriate where standard commercial-grade thread fit is acceptable, balancing ease of engagement with sufficient accuracy for most power-screw assemblies.

Installation Notes

This tap is installed and operated by machinists using manual tap wrenches or machine tapping equipment. Ensure the workpiece is securely fixtured and the spindle is properly aligned before tapping to avoid tap breakage. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Follow applicable shop safety procedures when handling sharp cutting tools.
