Directions for use

Always check that the screw size matches a 4 mm hexagonal drive before use. Fully insert the key into the screw head to reduce the risk of wear to the drive. For more stable tightening, use the straight end when access is perfectly aligned. The ball end is particularly useful for quickly engaging the screw or working at a moderate angle. It is advisable not to apply excessive torque if the fixing is fragile or if the screw already shows signs of wear.
