1.1 This specification covers the chemical, mechanical, and dimensional requirements for roof and rock bolts and accessories. Addressed in this specification are double-end threaded and slotted steel bars; fully grouted bolts and threaded bars; mechanical anchorage devices used for point anchorage applications; roof truss systems; partially grouted deformed bolts; formable anchorage devices; and other frictional anchorage devices. All of these products represent various designs used for ground support systems. This specification can be revised to address new technologies.

1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This hazard statement applies only to Section 10, Test Methods of this specification. This standard does not purport to address the safety concerns, if any, associated with its use.

This specification covers the chemical, mechanical, and dimensional requirements for roof and rock bolts and accessories. Addressed in this specification are double-end threaded and slotted steel bars; fully grouted bolts and threaded bars; mechanical anchorage devices used for point anchorage applications; roof truss systems; partially grouted deformed bolts; formable anchorage devices; and other frictional anchorage devices. All of these products represent various designs used for ground support systems. Threads on bolts or threaded bars may be cold rolled or machine cut on the hot-rolled bars. Bearing and header plates may be strengthened by cold forming or may be hardened by quenching in a liquid medium from above the austenitizing temperature and tempering. Hardened steel washers shall be through hardened by quenching in a liquid medium from above the austenitizing temperature and tempering. Test shall be performed in accordance with the following test methods: tensile strength; elongation; test for bearing and header plates; test for notched bendable bolts; and tests of roof truss components.
