WebbThis International Standard specifies clearance hole diameters for general purpose applications. These values result from bearing area calculations in connection with ISO bolt and nut product standards. NOTE ? Clearance holes for special applications should be selected on the basis of design requirements. WebbGrout clearances, overlength allowances on bolt projections and bolt clearances in base plate holes should be sufficient to allow for bolts that are out of tolerance and inaccurate levels of concrete. generally, Anchor Bolts should be within 3 mm of their required position and the top of concrete and bolts should be within 5 mm of their required level.
