This third edition cancels and replaces the second edition (ISO 6787: 2001),which has been technically
revised. The main changes compared to the previous edition are as follows:
—the reference number from ISO 1703: 2005 has been updated;
—the values for test mandrel width across flats and torque values in Table 2 have been updated;
—a footnote in Table 2 with reference to ISO 1711-1: 2016 has been added (moved from Clause 6).
BS ISO 6787:2018 specifies the dimensions of adjustable wrenches and the admissible clearance of the adjustable jaw. It also specifies test conditions to test the suitability of tool performance.
