Value Collection JY9037235 M20x2 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY9037235 is a straight flute tap designed for cutting M20x2 metric fine internal threads in through-holes and blind holes where chip evacuation is managed manually or with coolant flushing. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in a range of ferrous and non-ferrous materials. It features a plug chamfer — typically 3 to 5 leading threads — making it suitable for starting threads in through-holes or partially threading blind holes after a bottoming tap. Thread limit is D6, indicating a Class 6H tolerance for standard metric fine fits. Overall length is 4-15/32 inches with a 2-inch thread length.

This tap is used in machine shop, maintenance, and field repair applications where M20x2 metric fine threads are required. The straight flute geometry suits materials that produce short, brittle chips, such as cast iron, brass, and free-machining steel. It is appropriate for use in manual tap handles, tapping arms, or light-duty CNC tapping operations at controlled feed rates. Machinists, millwrights, and mechanical contractors working on metric-threaded assemblies — including hydraulic fittings, fastener repairs, and precision equipment — will find this tap a practical addition to their threading toolkit.

Key Features

• M20x2 metric fine thread profile for tight-tolerance threaded connections
• High-speed steel construction provides hardness and wear resistance across common workpiece materials
• Plug chamfer (3-5 lead threads) allows easy thread starting in through-holes
• 4 straight flutes for chip clearance and consistent thread form
• D6 thread limit ensures Class 6H tolerance for standard metric fine fits
• Bright, uncoated finish — no coating buildup to affect thread tolerances
• Right-hand thread direction, compatible with standard tapping equipment

Compatibility

Designed as a direct-fit replacement or stock tap for any application requiring M20x2 metric fine internal threads, compatible with standard tap holders and tapping arms sized for M20 shank geometry.

Installation Notes

This tap should be installed in a properly sized tap wrench, tapping arm, or machine spindle with a synchronized feed appropriate for the M20x2 pitch. Always ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the work surface before beginning the cut. Use an appropriate cutting fluid for the workpiece material to reduce heat buildup and extend tool life. Back the tap off periodically to break chips and prevent tap breakage, particularly in blind-hole applications.
