Basic hand tools

Introduction

In Pre-Technical Studies, understanding basic hand tools is essential for practical tasks and projects. These tools are used for various activities such as cutting, shaping, fastening, and measuring. Let's delve into the key concepts related to basic hand tools.

Hammer

• Definition: A hammer is a tool used for driving nails, breaking objects, or shaping metals by delivering an impact force.
• Example: If a nail needs to be driven into a piece of wood, a hammer is used to strike the head of the nail, forcing it into the wood.

Screwdriver

• Definition: A screwdriver is a tool designed for turning screws to either fasten or unfasten them.
• Example: When assembling furniture, a screwdriver is used to tighten the screws into the pre-drilled holes.

Pliers

• Definition: Pliers are hand tools used to grip, turn, and bend objects.
• Example: When fixing a broken wire, pliers are used to hold and twist the wire back together securely.

Common Mistakes

• Using the wrong tool for a specific task can lead to damage to the tool or the workpiece.
• Applying excessive force can result in the tool slipping or causing injury.
• Not using safety equipment such as goggles when using tools that produce flying debris.
