2 A video quiz will follow this Power Point Presentation

3 Tools Definition of a tool: “A muscle-powered device that solves a problem by providing a mechanical advantage in order to do useful work.” Examples of tools include hammer, screwdriver, tape measure, drill, saw, and wrenches.

4 Fasteners Definition of Fasteners: “Devices used to join or assemble parts together.” Examples of fasteners include nails, screws, nuts and bolts, hooks, and pins.

5 Hammer Hammers are used as levers. They can bang in nails with the head end or remove nails using the claw end. tml

6 Screwdrivers Basic Screwdriver. It is also called flat blade or flathead screwdriver. Phillips Head Screwdriver

7 A flathead screwdriver is meant to be used with slotted screws.

8 Phillips head screwdrivers are to be matched with Phillips head or crosshead screws.

9 Big Idea…… The end of the screwdriver must match up with the head of the screw in order to work!

10 When the screw matches with the surface of the wood, we say it is “Flush” with the board.

11 Pliers

12 Pliers are used to grip things. “ Use adjustable pliers to tighten or loosen nuts and bolts, pinch snap-rings, and other jobs that require a good grip.”

13 Drill Some drills are electric and some are hand drills. Drills bore holes into material such as wood or metal.

14 Saws Saws are used to cut materials. Saws can be electric or you can power them by hand.

15 Wrenches Adjustable wrench Combination (open and box) wrench Wrenches are used to tighten or loosen bolts and nuts.

16 Big Idea…. The wrench must fit the nut in order to turn it!

17 Measuring Tools Rulers (12 inches) measure short distances Tape measures are used to measure long distances like the length of a driveway. Yardsticks(36 inches or 3 feet) measure large things like the length of a room.

18 Fasteners- Nails Common fastener for wood A fast and strong method for joining wood. Used in building houses

19 Fasteners- Pins Pins are weak fasteners that hold light things.

20 Fasteners- Hooks Hooks are used to hold things.

21 Fastener- Screws Slotted screws and crosshead screws Put into material with a screwdriver that matches the screw head Screws pull together things to be joined Screws can be screwed into wood, metal, or plastic Stronger connection than nails

22 Fasteners- Nuts and Bolts Holes must be drilled first in each item Bolt is passed through both holes Nut is then threaded onto bolt and tightened A wrench tightens everything. Strongest connection

23 With some bolts you may need a screwdriver to tighten them. Look at the head of each bolt. Name the screwdriver used to tighten each bolt head.

24 You may need to use a wrench for the bolt and a wrench for the nut to tighten these nuts and bolts.
