Bolt clearances-19. Thumb rules from AISC. AISC Design Provisions • Chapter J of the AISC Specifications focuses on connections. Section J3 focuses on bolts and threaded parts 7 CE 405: Design of Steel Structures AISC Specification J3.3 indicates that the minimum distance (s) between the centers of bolt holes is 2 2/3 D. A distance of 3db is preferred. AISC Specification J3.4 indicates that the minimum edge distance (Le) from the center of the bolt to the edge of the connected part is given in Table J3.4 on page 16.1-61 Table J3.4 specifies minimum edge distances for sheared edges, edges of rolled shapes, and gas cut edges. AISC Specification J3.5 indicates that the maximum edge distance for bolt holes is 12 times the thickness of the connected part (but not more than 6 in.). The maximum spacing for bolt holes is 24 times the thickness of the thinner part (but not more than 12 in.). Specification J3.6 indicates that the design tension or shear strength of bolts is φ FnAb - Table J3.2 gives the values of φ and Fn - Ab is the unthreaded area of bolt. - In Table J3.2, there are different types of bolts A325 and A490..
