Machine screw-tap FANAR M4 short

Machine screw-tap FANAR M4 short is a compact tool designed to form or cut internal M4 metric threads in a range of materials. The short length design reduces overhang and improves rigidity when working in confined spaces or on shallow threaded holes. This FANAR tap is intended for use in machining setups, tapping heads, and hand tapping operations where precise M4 threads are required and compatibility with standard holders and machines is needed.

Advantages

The short geometry increases tool stiffness and reduces the risk of tap breakage in limited-access areas. High dimensional accuracy provides consistent thread form and fit for M4 fasteners. The tap is suitable for both forming and cutting operations depending on material and process, delivering reliable thread quality while minimizing cycle time in automated or manual tapping applications.

Suitable for

• Tapping M4 internal threads in confined or shallow holes
• Use in tapping heads and multi-spindle machines
• Hand tapping in repair and assembly tasks
• Small series production and prototype machining

Key specifications

• Thread size: M4 (metric)
• Configuration: short length tap for limited-access use
• Intended function: forming or cutting internal threads
• Compatibility: designed for use with standard tap holders and machines
• Application range: suitable for a variety of common engineering materials when used with appropriate cutting or forming parameters

How to use

Select the appropriate tap holder or chuck and secure the short FANAR M4 tap with the correct axial alignment. For cutting operations use suitable cutting fluid and advance the tap with steady feed, clearing chips regularly; for forming operations ensure the material and press setup are appropriate for thread forming. Follow machine or hand-tapping best practices: align the tap with the hole axis, apply controlled speed and feed, and reverse or back-off periodically to break and remove chips when cutting.

Usage recommendations

Use appropriate lubrication for cutting taps and ensure proper workpiece support to prevent misalignment. For forming operations verify material ductility and choose correct press force. Replace the tap if wear or damage affects thread quality or increases required torque.
