How to use

Insert the trzpieniowa shaft end of the Beta Tools 4 mm bit into a compatible bit holder or screwdriver chuck until it seats securely. Ensure the tip aligns with the fastener head before applying torque to avoid slippage. For powered drivers, select an appropriate speed and torque setting for the screw material to prevent damage to the tip or fastener. After use, inspect the bit for wear and replace when the tip no longer engages cleanly with fasteners.

Usage recommendations

Use the bit with correctly sized fasteners and appropriate torque settings to maximise service life. Store the bit in a dry, organised tool case to protect the tip profile and maintain readiness for professional or hobby applications.
