It is commonly used in various applications, such as assembling furniture, repairing appliances, and working on electronics. The simplicity and availability of screws with slotted heads make the minus screwdriver a popular choice for many DIY enthusiasts and professionals.

2. How does a minus screwdriver work?

A minus screwdriver works by exerting torque or turning force on the slotted head of a screw. The user places the tip of the screwdriver into the slot on the screw head and applies rotational force to turn the screw clockwise to tighten or counterclockwise to loosen it. The flat tip of the minus screwdriver engages with the sides of the slot, allowing the force to be transferred effectively.

To ensure proper engagement and prevent slippage, it is essential to use a minus screwdriver that matches the size and width of the screw slot. The tip should fit snugly into the slot to maximize torque transfer and minimize the risk of damaging the screw head or slipping and causing injury. It is also crucial to maintain the alignment between the screwdriver tip and the screw slot to avoid cam-out, which occurs when the tip slips out of the slot while applying force.
