Value Collection JY4993655 Straight Flute Tap M16x1

Product Description

The VALUE COLLECTION JY4993655 is a straight flute plug tap ground to M16x1.00 Metric Fine thread form for use in general threading operations on through holes and moderately deep blind holes. Manufactured from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread cutting performance across a broad range of ferrous and non-ferrous workpiece materials. The 4-flute straight flute design provides full chip support along the thread form and suits applications where cutting fluid or coolant is applied externally. Overall length is 3-13/16 inches with a thread length of 1-13/16 inches, and the right-hand D6 thread limit keeps the tapped hole within standard tolerance for metric fine fastener engagement.

This tap is suited for machine shop, maintenance, and production threading applications where M16x1.00 Metric Fine threads are required. The plug chamfer — typically 3 to 5 threads of lead-in — allows the tap to start in a drilled hole and progress through the full thread form without requiring a taper tap first. It is commonly used in manual tapping on drill presses and in CNC rigid tapping setups where straight flute geometry is preferred over spiral flute. Typical workpiece materials include mild steel, cast iron, aluminum, and brass.

Key Features

• M16x1.00 Metric Fine thread form with right-hand thread direction
• 4-flute straight flute geometry for chip support in through-hole and moderate blind-hole threading
• Plug chamfer for self-starting entry without a taper tap
• High-speed steel construction for durability across general shop materials
• Bright, uncoated finish with no added coating to alter dimensional tolerance
• D6 thread limit for standard metric fine fastener fit

Compatibility

Designed as a standard replacement or working tap for any machine or manual tapping application requiring an M16x1.00 Metric Fine, right-hand, plug chamfer straight flute tap with D6 thread limit.

Installation Notes

This tap is installed by licensed machinists or maintenance technicians using a standard tap wrench, tapping head, or rigid tapping cycle on a CNC machining center. Always ensure the workpiece is secured and the drill hole is sized to the correct M16x1.00 tap drill diameter before threading begins. Apply cutting fluid appropriate to the workpiece material to prolong tap life and improve thread quality. Never reverse a straight flute tap to break chips in a blind hole — clear chips by withdrawing the tap periodically.
