17.

Pick up the correct statement from the following:

 [A]. The minimum pitch should not be less than 2.5 times the gross diameter of the river [B]. The minimum pitch should not be less than 12 times the gross diameter of the rivet [C]. The maximum pitch should not exceed 10 times the thickness or 150 mm whichever is less in compression [D]. All the above.

Explanation:

No answer description available for this question.

 Surya Prakash said: (Jan 14, 2016) It is 800-2007 minimum pitch should not be less than 2.5 times the nominal diameter of fastener.

 Giddy said: (Oct 4, 2016) A, B seems same. Am I right?

 Faizan Raza Khan said: (Nov 17, 2017) The maximum pitch of the bolts for a compression member shouldn't exceed 12t or 200mm whichever is less. Where t = minimum thickness of plate joined. IS800;2007, clause 10.2.3.2 (pg no-74).

 Garry said: (Jan 19, 2018) It should be the normal diameter of rivet not the gross diameter these two are different things.

 Shubham said: (Jun 4, 2018) It should be 2.5 times the nominal diameter.

 Shaktisinh said: (Aug 4, 2018) Yes, it should be nominal dia of the rivet.

 Prakash said: (Dec 10, 2020) Yes, it's 2.5 times of nominal dia. Not gross dia.

 Komatwad Priya said: (Mar 4, 2021) Pich diameter not be less than 2.5 times gross diameter.
