In order to determine the required bolt length, the value in the table below should be added to the Grip (I.e., the total thi material, exclusive of washers) or enter the Grip in the Calculator above for single nut with washer. The values are gene for manufacturing tolerances to provide for full thread engagement of heavy hex nut, when installe For each hardened Bolted Parts (ASTM A325 & A490 BOLTS)
The slope of surfaces of bolted parts in contact with the bolt head and nut shall not exceed 1:20 with respect to plane normal to th axis. Bolted steel parts shall not be separated by gaskets and shall fit solidly together after bolts are tightened. Holes may be be p sub-punched and reamed, or drilled, as required by applicable code or specification. Standard holes shall have a diameter 1/1shall not be considered as reuse.
Oversized Holes may have nominal diameters up to: 3/16" larger than bolts 7/8" and less in diameter, 1/4" for 1" in diamete and 5/16" larger than bolts 1-1/8" and greater in diameter. Haredened washers shall be installed over oversized holes in an outer
