General

The original instigation for this change was only to correct the column title for Recess Torque in soft metric Table 2A from "lbf in" to "N m". However, the decision was then taken to remove the majority of soft metric information from the drg as the drg was ungainly in size the fixing is primarily of an inch design like the NAS1581 standard it is derived from. This therefore removed said Table 2A so various other corrections editorial improvements as listed below were incorporated.

Format notes (where applicable) updated to reflect change of organization name from SBAC to A|D|S. Refer to Foreword for more details.
