Bolt Holes definition

Bolt Holes. All bolt hole fabrication for high strength, slip critical bolted connections shall conform to the workmanship requirements of the Research Council on Structural Connections (RCSC) Specifications for Structural Joint Using A325 or A490 Bolts. Computer Numerically Controlled (CNC) drilling equipment shall be utilized as a manufacturing method as it allows for highly accurate hole location along with precise and rapid shop operations. Exceptions to CNC processing should be submitted in writing to the owner for approval, prior to commencing fabrication. Bolting: (Specifier define, select or delete these sections) All shop and field bolting shall comply with the AASHTO Construction Specifications, Section 11 and the Research Council on Structural Connections (RCSC) Specifications for Structural Joints Using A325 or A490 Bolts. Nuts shall be ASTM A563 grade DH and washers shall be ASTM F436, of corresponding finish. Shop and field bolts shall be tightened using the Turn-of-Nut Installation Method (AASHTO 11.5.6.4.4 or RCSC 8.2.1); or by a tension controlled (TC) wrench and bolt system (ASTM F1852); or by use of Direct Tension Indicating (DTI) washers.  A325 Type I Hex Head (Mechanically Galvanized, ASTM B695)  A325 Type I Hex Head (Hot-Dip Galvanized, ASTM A153)  A325 Type III Hex Head (Weathering Steel)  A325 Type TC Round Head (Mechanically Galvanized, ASTM B695)  DTI Washers (ASTM F959) Galvanized Steel Components: Fabricated truss elements and bolted beam connections shall be individually hot dip galvanized prior to assembly to ensure corrosion protection has been achieved between assembled elements and within truss joint plies. The only exception to this shall be floor beam end-plate assemblies which, if welded, shall require supplemental seal welds to prevent pickling acid leakage after galvanizing. All hot-dip galvanizing shall be in accordance with ASTM A-123. Damage to hot dip galvanized coatings resulting from welding, handling, or other factors shall be repaired in accordance with ASTM Standard Practice A-780. All bolts and fasteners shall be galvanized in accordance with ASTM specification A-153. The steel galvanizer of the bridge elements (other than bridge flooring) shall be a member of the American Galvanizer’s Association and shall provide the Bridge Owner a written limited warranty against corrosion of the superstructure components for a period of not less than 35 years. Shop Assembly: Shop assembly shall conform to AASHTO Construction Spe...
