ASTM A394-05e1

Standard Specification for Steel Transmission Tower Bolts, Zinc-Coated and Bare

SCOPE
1.1 This specification covers the chemical and mechanical requirements of hexagon and square-head zinc-coated steel bolts and atmospheric corrosion-resistant bolts, in nominal thread diameters of 1/2, 5/8, 3/4, 7/8 and 1 in. for use in the construction of transmission towers, substations, and similar steel structures. The various types of bolts covered in this specification are:
1.1.1 Type 0—Hot-dip zinc-coated bolts made of low or medium carbon steel.
1.1.2 Type 1—Hot dip zinc-coated bolts made of medium carbon steel, quenched and tempered.
1.1.3 Type 2—Withdrawn in 2005.
1.1.4 Type 3—Bare (uncoated), quenched and tempered bolts made of weathering steel.
1.2 Annex A1 of this specification covers hot-dipzinc-coated steel ladder bolts, step bolts, and support-equipment bolts.
1.3 Nuts and washers that are supplied under this specifcation that are hot-dip zinc coated shall be in accordance with 4.4.
1.4 Terms used in this specification are defined in Terminology F1789.
1.5 The values stated in ince-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 The following safety hazards caveat pertains only to the test methods portion, Section 11, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
