At what angle should you approach the removal of a screw?

Approaching the removal of a screw at a 90-degree angle is essential for several reasons. This angle aligns the tool, usually a screwdriver, directly with the screw head. When applied, this alignment maximizes the contact surface between the tool and the screw, minimizing slippage, which could strip the screw head.

Using a 90-degree approach allows for even torque distribution as the tool engages the screw, which is important for overcoming any resistance from corrosion, dirt, or wear that may have accumulated in the threads over time. This approach also helps maintain control while turning the screw, reducing the potential for injury or damage to the surrounding material.

In contrast, other angles like 45 degrees or 30 degrees could result in ineffective force application or cause stripping of the screw head. An angle of 180 degrees would be impractical, as it suggests that the tool is in line with the body of the screw rather than engaging it properly. Thus, a 90-degree angle is the optimal choice for screw removal to ensure effectiveness and safety.
