The slightly conical hole that naturally results from punching operations is acceptable, as noted in Table 3.1 of the RCSC Specification.The width of slotted holes that are produced by flame-cutting, or a combination of punching or drilling and flame-cutting, should generally be not more than 1⁄32 in. greater than the nominal width except that gouges not more .
Tip 15: Permit the use of short-slotted holes, especially in shear connections with the load transverse to the slot. Tip 16: Remember that all slip-critical bolted connections are pretensioned, but not all pretensioned bolts need to be slip-critical. AISC 360-10, Section J1.10 has a list of connections
