3 Unit 10 — Fastening and Prying Tools The main parts of a hammer are the head, face, claw, and handle. The hammer face may be smooth or milled.

4 Unit 10 — Fastening and Prying Tools Carpenters use both straight-claw and curved-claw hammers.

5 Unit 10 — Fastening and Prying Tools In addition to driving nails, straight-claw hammers are used to pry boards apart and to split pieces of lumber.

6 Unit 10 — Fastening and Prying Tools Curved-claw hammers provide better leverage when pulling nails than straight-claw hammers. A block of wood placed under the hammer head increases leverage and helps in removing the fastener.

7 Unit 10 — Fastening and Prying Tools Proper use of a hammer results in more efficient driving of nails.

8 Unit 10 — Fastening and Prying Tools When possible, nail from a thinner piece into the thicker piece.

9 Unit 10 — Fastening and Prying Tools Stagger nails when nailing near the end of a board. Placing the nails in a straight line may split the board.

10 Unit 10 — Fastening and Prying Tools To avoid splits in harder wood, blunt the end of the nail with a hammer, cut off the point of the nail, or drill a pilot hole for the nail.

11 Unit 10 — Fastening and Prying Tools If necessary to nail into end grain, drive the nails in at an angle to increase their holding power.

12 Unit 10 — Fastening and Prying Tools Toenails should be driven in at an angle so that approximately half of the nail is in each piece of wood.

13 Unit 10 — Fastening and Prying Tools Tacking is a procedure for temporary nailing. The head of the nail should stick out so that it can be easily withdrawn.

14 Unit 10 — Fastening and Prying Tools Driving nails at an angle increases the holding power between two pieces fastened face-to-face.

15 Unit 10 — Fastening and Prying Tools A nail set is used to drive a nail head below the surface of the wood.

16 Unit 10 — Fastening and Prying Tools Hatchets used in the carpentry trade have a nail-pulling slot at the side of the blade.

17 Unit 10 — Fastening and Prying Tools A strike tacker may be used to fasten floor underlayment.

18 Unit 10 — Fastening and Prying Tools A hammer tacker is used to fasten insulation batts.

19 Unit 10 — Fastening and Prying Tools Heavy-duty staple guns are used to fasten vinyl flooring, insulation, roofing paper, carpet padding, screening, carpet, and ceiling tile.

20 Unit 10 — Fastening and Prying Tools Standard, Phillips, and square-drive (Robertson) screwdrivers are used by carpenters to drive screws.

21 Unit 10 — Fastening and Prying Tools Screw shank and pilot holes should be drilled when fastening pieces of hard wood together with wood screws.

22 Unit 10 — Fastening and Prying Tools When driving screws, one hand turns the screwdriver while the other hand holds it in position.

23 Unit 10 — Fastening and Prying Tools The screwdriver tip and blade should be properly dressed (ground) to prevent the screwdriver from slipping from the slot.

24 Unit 10 — Fastening and Prying Tools Gripping tools, such as wrenches and pliers, are used to tighten bolts.

25 Unit 10 — Fastening and Prying Tools When using an adjustable wrench, be sure it is tightly adjusted to the nut. Pull the wrench so that the force is on the side of the fixed jaw.

26 Unit 10 — Fastening and Prying Tools For power tasks, a pair of pliers with an open grip span no greater than 3 1/2″ and a closed grip span of at least 2″ should be used.

27 Unit 10 — Fastening and Prying Tools A ripping bar is used to pry boards apart and remove large nails or spikes.

28 Unit 10 — Fastening and Prying Tools A ripping chisel may be used to pry materials apart.

29 Unit 10 — Fastening and Prying Tools A nail claw is used to pull nails driven flush with the lumber surface so they can be pulled out with a hammer or ripping bar.
