Hand Tools

  1. 1. A BRIEF INTRODUCTION TO HAND TOOLS
  2. 2.  Measuring  Fastening – Wrenches  Fastening – Screwdrivers  Fastening – Pliers  Cutting  Striking/Driving
  3. 3. A. Feeler Gauges B. Micrometer C. Telescoping Gauge D. Dial Caliper E. Tachometer F. Ruler A B C D E F
  4. 4. Feeler Gauge – To verify distance between parts. I.e. The gap in a spark plug. Micrometer - measure thickness and diameter
  5. 5. Telescoping Gauge – transfer distance from parts to measurement tool Dial Caliper – measure inside, outside, and depth of parts
  6. 6. Tachometer – measure engine speed in RPM Ruler – Measure linear distance
  7. 7. A. Open End B. Box End C. Combination D. Ratchet & Socket E. Adjustable F. Hex G. Impact H. Torque A B C D E F G H
  8. 8. Open End – Loosen/tighten bolt or nut with contact on two flats Combination- Loosen/tighten bolt or nut with convenience of open end and box end on same wrench Box End – Loosen/tighten bolt or nut; less likely to slip off than open end wretch
  9. 9. Ratchet and Socket – Loosen/tighten bolt or nut in tight locations Hex – Loosen/tighten hex screws Adjustable – Loosen/tighten bolt or nut in tight locations
  10. 10. Impact – Loosen/tighten bolt or nut with air or electric power with short, rapid impulses to socket Torque – Tighten bolt or nut specified torque
  11. 11. A. Standard B. Phillips C. Torx D. Double Ended Offset A B C D
  12. 12. Standard – Drive slotted head fastener Phillips – Drive Phillips head fastener
  13. 13. Torx – Drive Torx head fastener Offset – Drive slotted, Phillips, or Torx head fasteners in tight locations
  14. 14. A. Slip Joint B. Adjustable C. Locking D. Needle Nose E. Snap Ring A B C D E
  15. 15. Slip-Joint – Grip fasteners and parts Locking – Lock on fasteners and/or hold parts Adjustable – Grip large fasteners and parts
  16. 16. Needle Nose – Grip fasteners and/or parts in tight locations Snap Ring – Install and remove snap ring fasteners
  17. 17. A. Hacksaw B. Drill C. Cold Chisel D. File E. Tap F. Die G. Snip H. Diagonal Cutting Pliers A B C D E F G H
  18. 18. Hacksaw – Cut metal Cold Chisel – Cut and/or remove fasteners and metal Drill – Drill holes in material
  19. 19. Tap – Cut internal threads in predrilled holes File – Form and/or smooth material Die – Cut external threads
  20. 20. Snips – Cut sheet metal Diagonal Cutting Pliers – Cut wire and other material
  21. 21. A. Ball Peen Hammer B. Rubber Mallet C. Soft-Faced Hammer D. Center Punch E. Drive Pin Punch A B C D E
  22. 22. Ball Peen Hammer – Hammer and/or shape parts Soft-Faced Hammer – Hammer/drive tools and parts without damaging surfaces Rubber Mallet – Hammer parts without damaging surfaces
  23. 23. Center Punch – Mark center point for drilling a hole Drive Pin Punch – Drive fasteners, shafts, and bearings
  24. 24.  Keep tools sharp and in proper working order. Look for wear that could cause an injury, such as a pitted hammer face, damaged insulation on a pliers, or splintered handle.  Point cutting tools away from the body during use.  Grind excess metal from mushroomed chisels.  Organize tools to protect and conceal sharp cutting surfaces.
  25. 25.  Never use a hammer on another hammer. The impact of the hardened surfaces may cause the heads to shatter.  Do not carry tools in a pocket. Transport sharp tools in a holder or with the blade pointed down.  Remove fasteners by pulling the tool toward the body or pushing the tool away from the face
