What is the difference between a Phillips head and a flat head screwdriver?
Answer: Phillips has a cross-shaped tip; flat head has a single blade tip
A Phillips screwdriver has a cross-shaped (+) tip that fits Phillips head screws, while a flat head (slotted) screwdriver has a single flat blade that fits slotted screws. Phillips screws are designed to 'cam out' at a specific torque to prevent over-tightening.
What is a socket wrench used for?
Answer: Quickly tightening or loosening nuts and bolts
A socket wrench system uses interchangeable sockets that fit completely around a fastener, driven by a ratcheting handle. The ratchet mechanism allows continuous rotation without repositioning, making it faster and more efficient than open-end or box-end wrenches.
What type of pliers is specifically designed for gripping and turning round objects like pipes?
Answer: Tongue-and-groove pliers
Tongue-and-groove pliers (also called Channellock pliers or water pump pliers) have angled jaws with multiple adjustment positions, allowing them to grip round objects like pipes, fittings, and nuts of various sizes.
What is the purpose of a level (spirit level)?
Answer: Determining if a surface is horizontal or vertical
A spirit level (bubble level) determines whether a surface is perfectly horizontal (level) or vertical (plumb). It contains a sealed tube with a liquid and air bubble — when the bubble is centered between the marks, the surface is level or plumb.
What is a die grinder used for?
Answer: Precision grinding, polishing, and material removal in small areas
A die grinder is a small, high-speed rotary tool used for precision grinding, deburring, polishing, porting, and material removal in confined areas. It accepts various small grinding stones, burrs, and abrasive accessories.
What is the primary function of an impact wrench?
Answer: Delivering high torque through rapid rotational impacts
An impact wrench delivers high torque through rapid, successive rotational impacts rather than continuous force. This makes it highly effective for loosening stuck or over-torqued fasteners and for rapid assembly/disassembly in automotive and industrial work.
