Thread tap Wera M4 metric, 1 piece, model 05104667001

Wera Thread Tap M4 (single piece) is a precision metric tap designed to cut or repair M4 internal threads in a range of machinable materials. Supplied as one tap, this tool is compatible with standard hand tap holders and machines for controlled thread cutting operations. The tap’s geometry and manufacturing quality support accurate thread profiles suitable for maintenance, repair and assembly work where consistent M4 threads are required.

Advantages

The Wera M4 tap offers accurate thread form and dimensional consistency for repeatable results. Manufactured to tight tolerances, it delivers reliable cutting performance and good fit with standard M4 fasteners. Its single-piece design simplifies selection and storage when only occasional M4 tapping is needed, and it can be used in both hand-guided and machine-assisted tapping setups.

Suitable for

• Cutting new M4 internal threads in metal components
• Repairing damaged or worn M4 threads
• Creating M4 threads in plastic, aluminium and other machinable materials
• Workshop maintenance, precision assembly and small-series production

Key specifications

• Thread size: M4 metric internal thread
• Supply format: single-piece tap (one unit)
• Intended use: cutting or repairing internal threads
• Compatibility: suitable for hand tap holders and compatible tapping machines
• Typical materials: steel, aluminium, brass, plastics and similar machinable materials

How to use

Select a suitable drill size for the M4 tap and prepare the hole with correct alignment. Mount the tap in an appropriate hand tap holder or machine spindle, ensure secure clamping, and apply cutting lubricant appropriate to the work material. For hand tapping, start carefully to establish square engagement, then advance with controlled turns, backing off periodically to break chips. When using a machine, set appropriate feed and speed for the material and maintain adequate lubrication. After cutting, clean chips from the thread and inspect the fit with an M4 screw or thread gauge.

Usage recommendations

Use suitable cutting fluid for the work material, keep the tap aligned to prevent cross-threading, and clear chips frequently. For hardened or abrasive materials, consider progressive drilling or pre-treatment and use appropriate tool holders to reduce breakage risk. Store the tap dry and protected to avoid corrosion and maintain cutting edges.
