6. HARDWARE TOOLS
Hardware tools are grouped into these four categories:
• Electro-Static Discharge (ESD) tools
• Hand tools
• Cleaning tools
• Diagnostic tools

7. Electro-Static Discharge (ESD)
Tools
• Anti-static wrist strap – used to prevent ESD damage to computer
equipment.

8. • Anti-static mat – used to stand on or place hardware on to prevent
static electricity from building up.

9. Hand Tools
• Flat head screwdriver – used to loosen or tighten slotted screws.

10. • Philips head screwdriver – used to loosen or tighten crosshead screws.

11. • Torx screwdriver - used to loosen or tighten screws that have a star-like

12. • Hex driver – sometimes called a nut driver, is used to tighten nuts in the
same way that a screwdriver tightens screws.

13. • Needle-nose plier – used to hold small parts.

14. • Wire cutter – used to strip and cut wires

15. • Tweezers – used to manipulate small parts

16. • Part retriever – used to retrieve parts from location that are to small for
your hand to fit.

17. • Flashlight – used to light up areas that you cannot see well.

18. Cleaning Tools
• Having the appropriate cleaning tools is essential
when maintaining or repairing computers. Using
these tools ensures that computer components are
not damaged during cleaning.

19. • Lint-free cloth – used to clean different computer components without
scratching or leaving debris.

20. • Compressed air – used to blow away dust and debris from different
computer parts without touching the components.

21. • Cable ties – used to bundle cables neatly inside and outside of a
computer.

22. • Parts organizer – used to hold screw, jumpers, fasteners and other small
parts and prevents them from getting mixed together.

23. Diagnostic Tools
• Computers are easier to use and more dependable with each new
generation of hardware and operating system update, but that
doesn't mean they're problem-free. Here's the most popular tools for
diagnosing your computer problems:

24. • Multimeter – used to test the integrity of circuits and the quality of
electricity in computer components.

25. • Loopback Adapter – used to test the functionality of computer ports.
