A shop head on a 4/32 rivet is 1 1/2 diameters wide and .65 to 1/2 diameters tall when finished. That is the same rule for all solid rivet shop heads or buck tails, Convert 4/32 seconds from a fraction to a decimal, and it will be .125. Multiply 0.125 × 1.5, and you will end up at 0.1875 wide or 3/16" Multiply 0.5 times your diameter. At point 125 and you will arrive at .0625 or 1/16". Hope this helps, and thank you for the question.
I agree in most cases. For AMT students, they must be able to make the calculation to pass the class. Many older aircraft do not have comprehensive SRMs and the rules would need to be applied to select the correct rivets. Modern aircraft do have much better publications which eases the process. More on this can be found in th AC 43.13-1B.
Awesome! thank you sir
thanks for the info. im new to this and learning
Thank you!
Will this be on the test tomorrow?
How do I calculate a 4/32 rivet. What is the shop head and height and width! Thank you can you provides steps

This is great to understand the principles, but in reality this is all calculated for you in the SRM
