Its quenched and tempered medium-carbon alloy steel allowed for an impressive tensile strength of 150,000 psi, which is higher than the 64,000 psi of a grade 2 bolt. There are also countless proprietary types available, but most use some variation, or combination, of the following basics: The most common type of locking nut, they have a small nylon insert at the top of the nut, the ID of which is slightly less than the major diameter of the bolts thread. pWSGRHcSFlUmEhj6TAfsfCK9v64qkH6U1Tnz9BK0p/vMafd0xVP9OLta3rygK7xKWC8eNeDA04AD To get pounds force, you need to multiply the shear strength by the shear area. Therefore the equation should be: 91000*Pi* (5/16)^2 = 27000 pounds force. /;/metadata WebMetric Bolt Grades and Strength Calculator: Note: Breaking torque test applies to bolts and screws with thread less than M3 for which no breaking and proof loads are indicated in ISO 898-1, as well as to short bolts and screws with nominal diameters 3 mm to 10 mm which cannot be subjected to a tensile test. 2Ko9/i/1j2VVdQd2nsSrlgs4LENyoOLbn97LT51X54qiGl/0mM+p/ut9/U94/wDl7xVBWLP9X4sT Reference to Table 1 shows that the yield strength of a Grade 8 bolt is higher than the ultimate strength of a Grade 5 bolt.

The difficulty of keeping alluminium wheels tightly fastened to steel hubs with steel lugs and nuts is a classic example.

Establishing and maintaining appropriate fastener pre-load in a bolted joint is the principle on which all bolted joints work and is the chief determining factor in how strong, tight, and fatigue-resistant a bolted joint will be. At 50 yards I ripped the carriage bolt tops off and managed to pull the heads through the gong 3/8 square holes.
