Value Collection JY4990958 Straight Flute Tap M2.3x0.40

Product Description

The VALUE COLLECTION JY4990958 is a straight flute tap designed for cutting M2.3x0.40 metric coarse internal threads in ferrous and non-ferrous materials. Built from high-speed steel with a bright, uncoated finish, this plug-chamfer tap produces clean, accurate threads in through-holes and moderately deep blind holes. The 3-flute straight flute geometry provides rigid support and smooth chip flow in a range of materials. With an overall length of 1.75 inches and a thread length of 0.4375 inches, it is sized for compact threading applications in tight workpiece geometries. Right-hand thread direction is standard. This tap is used by machinists, tool-and-die makers, and maintenance technicians working at the M2.3 thread size range.

This tap is suited for manual tapping and low-speed machine tapping operations in small-part manufacturing, precision assembly, and maintenance and repair environments. The plug chamfer style, with a 3-5 thread lead, makes it appropriate for starting threads in through-holes and for general-purpose threading where a taper tap is not required. It is a common choice for threading soft steel, aluminum, brass, and similar machinable materials at this metric thread size.

Key Features

• M2.3x0.40 metric coarse thread form for standardized metric fastener compatibility
• High-speed steel construction provides hardness and wear resistance for general-purpose tapping
• 3-flute straight flute design offers rigid support and controlled chip evacuation
• Plug chamfer provides a 3-5 thread lead, suitable for through-holes and general starting
• Bright, uncoated finish suitable for use with standard tapping fluids across a range of materials
• Right-hand thread direction, D3 thread limit for close-tolerance metric threading

Compatibility

Designed as a general-purpose straight flute tap for cutting M2.3x0.40 metric coarse internal threads. Fits standard tap wrenches and machine tap holders sized for the tap shank at this overall length of 1.75 inches.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench or tapping attachment. Ensure the workpiece is securely clamped and the tap is properly aligned perpendicular to the work surface before threading begins. Apply appropriate tapping fluid for the material being threaded to extend tool life and improve thread quality. Do not force or reverse the tap abruptly in blind holes, as breakage at this small diameter is difficult to recover from.
