    Double shear tests of single 7/8-in. and 1-in. high-strength bolts are reported. Altogether, ninety-six A325 bolts were tested in A7 steel jigs or in A440 steel jigs. Eighty-four A354BC, A354BD, and A490 bolts were tested in jigs made of A440 or constructional alloy steel. The effect of a number of variables on the shear strength and deformation at ultimate load was studied.
