18 Fasteners- Nails Common fastener for wood A fast and strong method for joining wood.Used in building houses
19 Fasteners- PinsPins are weak fasteners that hold light things.
21 Fastener- Screws Slotted screws and crosshead screws Put into material with a screwdriver that matches the screw headScrews pull together things to be joinedScrews can be screwed into wood, metal, or plasticStronger connection than nails
22 Fasteners- Nuts and Bolts Holes must be drilled first in each itemBolt is passed through both holesNut is then threaded onto bolt and tightenedA wrench tightens everything.Strongest connection
23 With some bolts you may need a screwdriver to tighten them 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.
