• Wood screws, machine screws, sheet metal screws, self-tapping screws

• Anchors, dowels, clamps, adhesives

• Screws, nails, glue, tape

Explain the difference between wood screws and machine screws.

• Wood screws are designed for wood, while machine screws are for metal or other materials

• Wood screws are for concrete, while machine screws are for metal

• Wood screws are for metal, while machine screws are for plastic

• Wood screws are for plastic, while machine screws are for wood

Name two different types of bolts and describe their specific uses.

• Round bolts and square bolts

• Hex bolts and carriage bolts

• Screw bolts and nail bolts

• Flat bolts and wing bolts

What are the main differences between hex bolts and carriage bolts?

• Thread pitch and coating

• Material and color

• Head shape and usage

• Length and diameter

What are the functions of nuts and washers in fastening systems?

• Nuts hold the washers in place

• Washers are used to tighten the fastener

• Nuts and washers are purely decorative

• Nuts secure the fastener and washers distribute the load.

Explain the purpose of using lock washers in fastening applications.

• To make the nuts and bolts easier to remove

• To add extra weight to the fastening application

• To prevent nuts and bolts from loosening due to vibration or torque.

• To provide a decorative element to the fastening application

Describe two different types of anchors and their applications.

• Expansion anchors and Toggle anchors

• Screw anchors and Nail anchors

• Bolt anchors and Hook anchors

• Adhesive anchors and Magnetic anchors

What are the advantages of using expansion anchors over adhesive anchors?

• Expansion anchors are more difficult to install than adhesive anchors

• Expansion anchors provide better holding strength and can be used in a wider range of base materials compared to adhesive anchors.

• Expansion anchors are more expensive than adhesive anchors

• Expansion anchors are less durable than adhesive anchors

What are threaded fasteners and how are they different from non-threaded fasteners?

• Threaded fasteners have threads on their shafts that allow them to be screwed into a matching threaded hole, while non-threaded fasteners do not have threads and are typically secured with a nut or other fastening device.

• Threaded fasteners are used for non-permanent connections, while non-threaded fasteners are used for permanent connections

• Non-threaded fasteners have threads and are screwed into a matching hole

• Threaded fasteners have no threads and are secured with a nut

Explain the importance of thread pitch in threaded fasteners.

• Thread pitch is important because it determines how tightly the fastener will hold the materials together and affects the strength and stability of the connection.

• Thread pitch determines the length of the fastener

• Thread pitch only affects the color of the fastener

• Thread pitch is not important in threaded fasteners
