Gives form, dimensions, sizes and hardness requirements.

This British Standard specifies dimensional, testing and other requirements for ring wrenches for metric, unified and British Standard hexagon bolts, nuts and machine screws specified in BS 916, BS 1083, BS 1768, BS 1769, BS 1981, BS 3139, BS 3692, BS 4183, BS 4190, BS 4395, ISO 272, and for hexagonal headed bolts of various materials in the aerospace series.

It covers hexagon and bi-hexagon double-ended ring wrenches in the following range:

metric wrenches 3.2 mm to 60 mm (across flats);

unified wrenches ¼ in to 2 in (across flats);

BS wrenches, ¼ in to 1⅜) in (thread diameter) and Whitworth (large) wrenches, 3/16 in to 1¼ in (thread diameter).

Appendix A describes a test for resistance to torque and Appendix B gives guidance on the safe use of ring wrenches. Appendix C lists information to be supplied by the purchaser when ordering ring wrenches.

The principal requirements of this standard also apply to single-ended ring wrenches except that the overall length of single-ended ring wrenches are subject to agreement between the purchaser and the supplier.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
