Finding a screwdriver that can bend at a 90-degree angle to reach a screw with limited clearance can be challenging, but there are specialized tools available that can help you with this specific task. You may want to consider looking for a "flexible shaft screwdriver" or a "right-angle screwdriver."
Flexible Shaft Screwdriver: A flexible shaft screwdriver has a bendable and flexible extension that allows you to reach screws in tight or awkward spaces. The shaft can be bent into various angles, including 90 degrees, making it suitable for the type of clearance you mentioned.
Right-Angle Screwdriver: A right-angle screwdriver is designed with a 90-degree angle between the handle and the shaft, allowing you to access screws in tight spaces. This type of screwdriver is more rigid than a flexible shaft screwdriver but is still effective in situations with limited clearance.
You can find these types of screwdrivers in hardware stores, home improvement centers, or online retailers. If you're having trouble locating one locally, searching online stores or specialty tool websites should provide you with various options.
When purchasing, pay attention to the length of the screwdriver and the clearance it can handle to ensure it fits your specific needs. Additionally, consider the quality and brand of the tool to ensure it will be durable and reliable for your project.
