Value Collection JY9037367 M28x2 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY9037367 is a straight flute tap designed for cutting M28x2 metric fine internal threads in a wide range of materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread formation in ferrous and non-ferrous metals under typical shop and field conditions. The plug chamfer style provides a moderate lead-in of approximately 3 to 5 threads, making it well suited for through-hole applications. With 4 flutes and a D8 thread limit, it produces consistent 6H class-of-fit threads suitable for standard metric fastener assemblies. Overall length is 5.4375 inches with a thread length of 2.5625 inches.

This tap is used in machine shops, maintenance facilities, and manufacturing environments where metric fine threads are required. The M28x2 pitch is common in precision assemblies, automotive components, and industrial equipment where a finer thread pitch provides greater clamping force and vibration resistance compared to coarse-pitch alternatives. It is intended for use in drill press, lathe, or tapping-arm setups and may also be used with a tap wrench for hand tapping in repair and retrofit scenarios. Right-hand thread direction matches standard fastener orientation.

Key Features

• M28x2 metric fine thread form for precision thread-cutting applications
• High-speed steel construction provides hardness and wear resistance across common work materials
• Plug chamfer (3 to 5 thread lead-in) optimized for through-hole tapping
• 4-flute straight design channels chips efficiently in short-to-moderate depth holes
• 6H class of fit with D8 thread limit ensures compatibility with standard metric 6H fasteners
• Bright, uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as a direct-use tap for applications requiring M28x2 metric fine, 6H class-of-fit internal threads. Compatible with standard tap holders and tapping chucks sized for the shank dimensions of this tool.

Installation Notes

This tap should be installed and operated by a machinist or qualified tradesperson familiar with thread-cutting procedures. Always secure the workpiece properly and use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Ensure the tap is properly aligned with the pilot hole before applying torque to avoid tap breakage. Follow all applicable shop safety practices and tool manufacturer guidelines when operating tapping equipment.
