The thickness of flat head rivet for diameter 'd' is:
Show Hint
- $0.2 \, d$
- $0.25 \, d$
- $0.3 \, d$
- $0.35 \, d$
The Correct Option is B
Solution and Explanation
A flat head rivet is a solid permanent fastener consisting of a cylindrical shank of diameter $d$ and a flat, cylindrical head at one end.
Step 2: Proportional Standards of Flat Head Rivets:
As per Indian Standard IS:2155 (and general mechanical engineering conventions), the standard proportions of a flat head rivet in terms of its shank diameter $d$ are:
• Head Diameter ($D$): $D = 2.0 \, d$
• Head Thickness or Height ($H$): $H = 0.25 \, d$
Step 3: Verification of Options:
Among the given options, $0.25 \, d$ corresponds exactly to the standard head thickness of flat head rivets. Therefore, option (B) is correct.
