Title:Calibration Tests of A490 High-Strength Bolts
Author(s):Troup, E.W.J.; Chesson, Jr., E.
Subject(s):Bolts and nuts -- Testing
calibration tests
Abstract:Over fifty calibration tests on 7/8 in. diameter ASTM. A490 high-strength bolts were conducted. Data on bolt tension, elongation, turns of nut, and general behavior were analyzed. Comparisons were made of bolt behavior when torqued in a commercial load cell and in a solid steel block: it was found that a significant difference exists between these two conditions. The general characteristics of the A490 high-strength bolt appear to be similar to those of the familiar A325 bolt, but the physical properties of the new bolt will provide greater fastener strength and joint clamping.
