Long slotted holes may be used in one of the connected parts at any individual faying surface without regard for the direction of applied load on connections in which the allowable slip resistance is greater than the applied force. (3) Long slotted holes may be used in one of the connected parts at any individual faying surface in connections designed on the basis of allowable stress on the fasteners provided the load is applied approximately normal (between 80 and 100 degrees) to the axis of the slot. Washers shall be installed over short-slotted holes in an outer ply when high strength bolts are used, such washers shall be hardened. Short slotted holes may be used without regard for the direction of applied load in any or all plies of connections in which the allowable slip resistance is greater than the applied force. (2) Short slotted holes may be used in any or all plies of connections designed on the basis of allowable stress on the fasteners provided the load is applied approximately normal (between 80 and 100 degrees) to the axis of the slot. Hardened washers shall be installed over oversized holes in an outer ply.
Oversized holes shall not be used in bearing-type connections. (1) Oversize holes may be used in any or all plies of connections in which the allowable slip resistance of the connection is greater than the applied load. When approved by the engineer, oversize, short slotted holes or long slotted holes may be used subject to the following joint detail requirements: may be introduced into slip-critical connections designed on the basis of standard holes without reducing the allowable shear stress of the fastener. Standard holes shall be provided in member-to-member connections, unless oversized, short-slotted or long-slotted holes in bolted connections are approved by the designer. The maximum sizes of holes for bolts are given in the table below, except that larger holes, required for tolerance on location of anchor bolts in concrete foundations, are permitted in column base details. larger in diameter than the bolt body, certain conditions encountered in field erection require greater adjustment than this clearance can provide and approval from the engineer is required. In the absence of approval by the engineer for use of other hole types, standard holes shall be used in high strength bolted connections.Īlthough most holes for high-strength bolts are made 1/16-in. This provides a certain amount of play in the holes, which compensates for small misalignment’s in hole location or assembly, and aids in the shop and field entry of fasteners. larger in diameter than the nominal size of the fastener body. Standard hole sizes for bolts are made 1/16-in. It does not store any personal data.This information applies to the American Steel Industry.
