What is the primary purpose of drilling a pilot hole before driving a screw into wood?
Answer: To prevent the wood from splitting and guide the screw accurately
A pilot hole is drilled slightly smaller than the screw's diameter to reduce the wood-splitting force as the screw is driven in, while also keeping the screw properly aligned.
Which type of wrench provides the most surface contact with a fastener and is least likely to slip or round off the corners?
Answer: Box-end (ring) wrench
A box-end wrench fully encircles the nut or bolt head, gripping all six sides (or twelve points) and distributing force evenly, which greatly reduces the chance of slipping and rounding the fastener.
What does sandpaper grit number indicate?
Answer: The number of abrasive particles per square inch — higher numbers mean finer grit
Grit number refers to the density of abrasive particles: a higher grit number (e.g., 220) means smaller, more densely packed particles that produce a smoother finish, while a lower number (e.g., 40) means coarser particles for rapid material removal.
Which hand tool is specifically designed to measure both the inside and outside dimensions of objects such as pipes or cylinders?
Answer: Vernier calipers
Vernier calipers have both outer jaws (for external measurements) and inner jaws (for internal measurements), making them the correct tool for precisely measuring diameters and depths of cylindrical objects.
What is the function of flux when soldering metal joints?
Answer: It cleans the metal surfaces and prevents oxidation so the solder flows and bonds properly
Flux chemically cleans metal surfaces and prevents new oxide layers from forming during heating, allowing molten solder to wet and bond to the base metal effectively. Without flux, solder beads up and produces weak, cold joints.
Which type of screwdriver drive is identified by a six-pointed star shape and is commonly used in electronics and automotive applications to resist cam-out?
Answer: Torx (star)
The Torx drive has a six-pointed star recess that allows higher torque to be applied without the driver slipping out (cam-out). It is widely used in electronics, appliances, and automotive assemblies where precise torque is critical.
