Note that reamed holes must meet the provisions for minimum spacing and minimum edge distance in AISC Specification Sections J3.3 and J3.4, respectively. Bolt pitch spacing.

6. /Filter /FlateDecode Reports of large diameter structural bolts not fitting into standard holes, even when properly aligned, led AISC to study and draft language for AISC 360-16 that increases the standard hole diameter (STD) and slot width for structural bolts 1-inch diameter and above to 1/8-inch larger than the bolt diameter, replacing … Burrs larger than 1 ⁄16 in. AISC Specification Table J3.3 is based upon the RCSC Specification Table 3.1 and contains the maximum dimensions of standard, oversized, short-slotted and long-slotted holes. Standard Hole … As per AISC We have 3 type of bolts which are commonly used. It is not intended to address limitations on the amount of material that is removed by reaming at an individual bolt hole, for example, which is limited by the bolt-hole size and tolerance requirements in the AISC and RCSC Specifications."

Additional considerations may be warranted for much thicker plates, steel grades other than those tested and cyclically loaded structures. Punching usually is the most economical method. bolt dia d b = 0.750 [in] bolt hole dia d h = 0.813 [in] AISC 14 th B4.3b. AISC, Steel Design Guide Series 1, Column Base Plates, suggests that using oversize holes meeting these criteria may still not accommodate field varia- tions in anchor bolt placement and suggests adding 1/4 in.

Thermal cutting, subject to surface quality requirements as discussed in 2.4.2The slightly conical hole that naturally results from punching operations is acceptable, as noted in Table 3.1 of the RCSC Specification. A general rule of thumb is given in AISC Design Guide #10 Erection Bracing of Low-Rise Structural Steel Frames 1: the minimum thickness should be one-third the diameter of the anchor rod and that the minimum diameter (or length and width for a non-circular washer) should be 1-in. by 1 in.). The AISC Structural Steel Educational Council cites the following example: “If bolts … The prescribed limitations are summa-rized below. by 1¼-in. s v = 3.000. Anchor Bolt Tolerances For Construction Pros . (i.) For bolts larger than 1 ½ in the AISC allows the use of ASTM A449 provided that they are not used in slip-critical connections. The placement of bolt holes is prescribed by AISC. The hole diameter in the die is typically 1/32 larger than the punch for thinner material, and typically 1/16 larger for thicker material.

The language in Specification Section J3.8 is to preclude a rupture failure that could result in the loss of the connection between the elements if slip were to occur. For example, a 13∕16-in. bolt hole to the edge of plate minus one half of the bolt diameter plus 1/8 in.
