Which drawing shows the correct AS 1100 standard representation of a Ø10 non-structural bolt head?
 

Show Answers Only

`A`

Show Worked Solution

The thickness of a bolt head is equal to 0.7 times the diameter, and the width of a bolt head (across peaks) is equal to 1.8 times the diameter.

`=>A`

This diagram shows the cross-section of a highway pavement drawn using AS 1100 drawing standards.
 

Explain the benefits of using AS 1100 drawing standards in the preparation of engineering drawings such as the one above.   (3 marks)

Benefits of using AS 1100 standards

→ Communication between manufacturers and designers is of higher quality, more accurate and involves fewer ambiguities.

→ AS 1100 is based on international standards so drawings can be easily shared between countries.

→ One project can be assigned multiple designers.

→ Cost effective as interpretation errors are minimised.

What is the thickness of a standard nut that fits a M20 × 2 bolt?

  1. 10 mm
  2. 16 mm
  3. 18 mm
  4. 20 mm
Show Answers Only

`B`

Show Worked Solution

→ AS1100 standards state the width of a nut is 0.8 x the diameter of the bolt.

→ 0.8 × 20 = 16 mm

`=>B`

Notes:

→ Thread must be properly drawn to the correct length

→ Nut dimensions must be correct according to AS1100

→ Question states no hidden detail or dimensions are to be shown

→ Centrelines must still be shown

→ Ensure the drawing is completed from the correct viewing direction
