Hand Tap Set FANAR M4, 3 pieces (A2-235801-0040)

FANAR hand tap set for M4 provides three taps intended for cutting M4 metric internal threads by hand. The set covers the standard three-stage tapping sequence — roughing, intermediate and finishing — and is designed for use with a tap wrench in common workshop and repair situations. These taps are suitable for threading through holes in metal, plastic and other machinable materials where M4 threads are required for fasteners or repair operations.

Advantages

The three-piece arrangement supports progressive material removal to reduce tap breakage and improve thread quality in manual tapping operations. Taps are matched for a standard M4 thread profile and intended for general workshop use, making them versatile for maintenance, assembly and small-scale production tasks. Their manual design allows precise control of cutting depth and feed when used with a suitable tap handle or wrench.

Suitable for (use cases)

• Repairing or restoring M4 threads in metal components
• Creating new M4 threaded holes in plastic or softer metals
• Small workshop machining and maintenance tasks
• Prototyping and light assembly work requiring M4 fasteners

When it may not be suitable

This hand tap set is intended for manual use and low- to medium-volume work; it is not designed for high-production automated tapping on CNC machines or tapping under heavy-duty industrial conditions. For very hard materials, hardened steel, or large-diameter production runs, machine taps or specialized tooling with appropriate coatings and geometries may be more suitable.

Key specifications

• Thread size: M4 (metric)
• Set composition: three taps for progressive tapping stages (rough/intermediate/finish)
• Intended use: manual tapping with a tap wrench or handle
• Materials suitable for: common machinable metals, plastics and similar materials
• Application: internal thread cutting for M4 fasteners

How to use

Secure the workpiece and drill the correct pilot hole for M4 tapping using the recommended drill size for the material. Mount the appropriate tap in a tap wrench, apply cutting lubricant suitable for the material, and start the tap square to the hole. Use the roughing tap first to remove bulk material, back off periodically to clear chips, then follow with the intermediate and finishing taps to achieve the final thread form. Clean the thread and inspect the fit of the M4 fastener after tapping.

What to consider before purchase

• Confirm the required thread size is M4 and that the material is suitable for manual tapping
• Ensure you have a compatible tap wrench/handle and appropriate drill sizes for pilot holes
• Consider cutting fluid and chip removal methods for the material you will tap

Usage recommendations

For best results, use progressive tapping stages included in the set, keep the tap aligned, apply appropriate lubricant, and clear chips regularly. Replace taps showing wear or damage to avoid poor thread quality or breakage.
