Value Collection JY4996021 Hand Tap M14x0.50 Metric Special

Product Description

The VALUE COLLECTION JY4996021 is a straight-flute hand tap designed for cutting M14x0.50 metric special internal threads in a wide range of materials. Built from high speed steel with a bright uncoated finish, this 4-flute tap delivers consistent thread formation in both through-hole and blind-hole applications. It carries a plug chamfer, which provides a gradual lead-in of approximately 3 to 5 chamfered threads, making it well suited for through-hole work or starting a thread before a bottoming tap is used. The overall length is 3-19/32 inches with a thread length of 1-21/32 inches, and it conforms to a 6H class of fit with a D3 thread limit for consistent dimensional accuracy.

This tap is used in machining and tool-and-die operations where a fine-pitch M14x0.50 metric special thread is required. The M14x0.50 pitch is a non-standard fine pitch not found in the common metric coarse or standard fine series, making this tap appropriate for specialized fastener applications, precision instrument housings, or custom mechanical assemblies. It is driven by a standard tap wrench or tapping attachment and is suited to manual tapping operations in job-shop and maintenance environments.

Key Features

• M14x0.50 metric special thread form for non-standard fine-pitch applications
• High speed steel construction provides durability across ferrous and non-ferrous materials
• Bright uncoated finish allows visual inspection of the cutting surface before and after use
• Plug chamfer with 4 flutes for smooth thread entry and chip clearance in through-hole tapping
• 6H class of fit with D3 thread limit ensures consistent, measurable thread tolerance
• Right-hand thread direction compatible with standard tap wrenches and tapping attachments

Compatibility

Designed as an OEM-style replacement or direct-use hand tap for applications requiring an M14x0.50 metric special right-hand internal thread with a 6H fit class.

Installation Notes

This tap is installed by a machinist or maintenance technician using a standard tap wrench or machine tapping attachment. Before tapping, drill the correct tap drill diameter for M14x0.50 and secure the workpiece firmly. Apply appropriate cutting fluid for the material being tapped to extend tool life and improve thread finish. Do not force the tap — back off periodically to break chips, especially in blind holes.
