Final answer:
Nut drivers are used to adjust fasteners with a hexagonal shape such as machine screws, bolts, and hex nuts. They require the correct size for a proper fit and can turn these fasteners to tighten or loosen them. Screws and nuts come in various metals and may have different coatings.
Step-by-step explanation:
Nut drivers are tools that are designed to tighten and loosen nuts, which are typically hexagon-shaped fasteners. The types of fasteners that can be adjusted using a nut driver have a hexagonal outer shape, commonly found in various hardware components such as bolts. When using a nut driver, you can apply torque to turn the nut or bolt. This is pertinent when you're trying to either secure components together or loosen them for disassembly or maintenance.
Fastener Types Suitable for Nut Drivers
- Machine screws with a hexagonal head
- Bolts with a hex head, including carriage bolts, flange bolts, and eye bolts
- Hex nuts are used in various assembly jobs
When selecting a nut driver, it is crucial to choose the correct size that matches the fastener's head size to provide a snug fit. This ensures that the tool can exert enough grip and mechanical advantage to turn the fastener without slipping or damaging its corners.
Materials of Screws and Nuts
Screws and nuts can be made from a range of metals, including steel, stainless steel, brass, and sometimes aluminum. They may also have different coatings for corrosion resistance, appearance, and to reduce friction.
