Value Collection JY9036724 Straight Flute Tap M16x1.25

Product Description

The VALUE COLLECTION JY9036724 is a straight flute tap designed to cut M16x1.25 Metric Special internal threads in a bottoming chamfer configuration. Built from high-speed steel (HSS) with a bright uncoated finish, this tap produces a 6H class of fit with a D5 thread limit. The four-flute straight flute geometry is well suited for threading in materials that produce short or broken chips, providing stability and accuracy in both manual and machine tapping operations. With an overall length of 3.8125 inches and a thread length of 1.8125 inches, it accommodates blind holes requiring threads close to the bottom of the bore.

This tap is used in machining and fabrication applications where M16x1.25 fine-pitch metric threads are required. The bottoming chamfer style - with just 1 to 2 lead threads - allows the tap to thread nearly to the bottom of a blind hole after initial thread formation with a plug or taper tap. It is appropriate for use in machine shops, maintenance and repair operations, and production environments. Right-hand thread cutting matches the standard fastener orientation for M16x1.25 assemblies across automotive, industrial, and mechanical applications.

Key Features

• M16x1.25 Metric Special thread form with 6H class of fit for standard tolerance threading
• Bottoming chamfer allows threading close to the base of blind holes
• Four straight flutes provide stability and chip control in short-chipping materials
• High-speed steel construction offers durability across a range of workpiece materials
• Bright uncoated finish - no coating buildup concerns, easy to inspect for wear
• D5 thread limit for consistent fit with standard M16x1.25 fasteners
• Right-hand cut matches standard M16x1.25 fastener orientation

Compatibility

Designed as an OEM-style replacement or direct-use straight flute tap for applications requiring M16x1.25 Metric Special right-hand threads with a 6H class of fit and bottoming chamfer in production or maintenance tapping operations.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using a tap wrench, tapping head, or CNC machine spindle. Always ensure the workpiece is securely fixtured and the tap is properly aligned before cutting to avoid tap breakage. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. When tapping blind holes with a bottoming tap, complete initial thread formation with a taper or plug tap first to avoid overloading the bottoming tap at entry.
