Value Collection JY4996161 Straight Flute Tap M20x1.00

Product Description

The VALUE COLLECTION JY4996161 is a straight flute plug tap designed for cutting M20x1.00 metric fine internal threads in metalworking and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap offers reliable performance across a range of ferrous and non-ferrous materials. The plug chamfer features a moderate lead-in that suits through-holes and deeper blind holes where thread starting is less restricted. With 4 flutes and a 2-inch thread length, the JY4996161 provides consistent chip clearance and thread form across the full cutting depth. Overall length is 4-15/32 inches, and the right-hand thread direction follows standard machining convention.

This tap is suited for production and maintenance machining environments where M20 fine-pitch threads are required. Metric fine thread taps at this pitch are commonly used in applications that demand greater thread engagement strength and vibration resistance than coarse-pitch threads provide, such as precision assemblies, hydraulic fittings, and fastener repair. It is installed by machinists, tool-and-die makers, and maintenance technicians using a tap wrench, tapping head, or CNC tapping cycle. The D7 thread limit designation indicates the tolerance class, which is appropriate for standard fit applications.

Key Features

• M20x1.00 metric fine thread form for high-engagement and vibration-resistant thread cutting
• High-speed steel construction for durability across a broad range of workpiece materials
• Plug chamfer with moderate lead-in suits both through-holes and accessible blind holes
• 4-flute design promotes chip clearance and consistent thread form during cutting
• D7 thread limit for standard tolerance fit applications
• Right-hand thread direction consistent with standard machining practice

Compatibility

Designed as a standard replacement or utility tap for metalworking operations requiring M20x1.00 metric fine internal threads. Compatible with standard tap wrenches, tapping heads, and CNC machine tool holders sized for M20 taps.

Installation Notes

This tap is installed by qualified machinists or maintenance technicians familiar with thread-cutting operations. Secure the workpiece firmly before tapping and ensure the hole is drilled to the correct tap drill diameter for M20x1.00 metric fine threads. Apply appropriate cutting fluid to reduce heat and extend tool life. When tapping by hand, use a tap wrench and advance with a back-off motion to break chips and prevent tap seizure.
