摘 要：正According to the current ISO and JIS Standards,in the table of mechanical properties of steel bolts,the impact strength is specified only for the bolts of nominal thread diameter larger and including 16 *** the steel bolts of nominal thread diameter smaller than 16 mm,the impact strength is not specified,because the impact strength test piece of standard dimensions can not be machined from those smaller *** paper reports the results of charpy impact strength tests using smaller test pieces machined from steel bolts of nominal thread diameter smaller than 16 mm,and proposes a test method for impact strength of steel bolts of nominal thread diameter smaller than 16 mm.
