There is a standard quality requirement addressed by the government to specify each and every material used in construction with the correct fastener
. To avoid any unforeseen breakage or any structure failure, one must observe the tensile strength and shear values accurately for the fasteners applied. If you find it too technical for you, then do make sure you send the fastener specification to the lab to testify scientifically, in order to fulfill the requirement for the safety of all the construction workers.
