Value Collection JY4992301 M7x0.75 Straight Flute Tap 6H Hss

Product Description

The VALUE COLLECTION JY4992301 is a straight flute plug tap designed for cutting M7x0.75 Metric Fine internal threads in a variety of materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread quality in production and maintenance environments. The plug chamfer — typically 3 to 5 threads — makes it well suited for through-hole applications where the tap can pass fully through the workpiece. With 4 flutes and a 6H class of fit, it produces threads within standard tolerance ranges accepted in precision mechanical assemblies. Overall length is 2-23/32 inches with a thread length of 1-1/8 inches.

This tap is used in machine shops, maintenance facilities, and manufacturing operations where Metric Fine thread forms are required. M7x0.75 is a fine-pitch designation commonly found in precision fastener applications, instrument components, and close-tolerance assemblies. It is appropriate for hand tapping or machine tapping operations in steel, aluminum, brass, and similar machinable materials. Machinists and toolroom technicians are the primary users.

Key Features

• M7x0.75 Metric Fine thread form for fine-pitch internal threading
• Plug chamfer style suited for through-hole tapping operations
• 4-flute geometry for stable cutting action and chip distribution
• 6H class of fit — standard tolerance for general-purpose metric threads
• D4 thread limit for controlled oversize tolerance during cutting
• High-speed steel construction with bright, uncoated finish — no additional coating drag

Compatibility

Designed as a standard straight flute plug tap for M7x0.75 Metric Fine through-hole threading applications in general machining and maintenance operations.

Installation Notes

This tap is installed by machinists or toolroom technicians using a tap wrench, tapping head, or CNC machine with appropriate feed rate control. Always use cutting fluid suited to the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before tapping and align the tap perpendicular to the hole to prevent tap breakage. Do not reverse direction abruptly in hand tapping — back off periodically to break chips.
