WebSAE J429 Grade 8 – This grade of bolts is made of medium-strength carbon or alloy steel and possesses the highest level of strength up to 150,000 psi. As such, it’s an ideal … WebAnything over a grade 8 fastener (and very rarely a grade 8) Stress above a threshold – There is no clear way to calculate this, unfortunately. Generally speaking a fastener designed to 50% proof will not be high enough. If it is an engineered fastener at 75% of proof of higher, this could lead to an issue. Hydrogen – From the electroplating.
Web39 rows · Grade 8 Standard Specification for Carbon and Alloy Steel Nuts for Bolts for … WebProof load test on threaded fasteners to ISO 898-1 The proof load test (section 9.6) is a tensile test that is only performed up to a pure intended test load. The exact test load depends on the thread, diameter of the fastener and the property class. These are listed in a table in ISO 898-1.
WebThe torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Clamp load calculated as 75% of the proof load when specified by the standard. ASTM A307 utilized 75% of 36,000 PSI. Torque values for 1/4 and 5/16-in series are in inch-pounds.
WebProof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation.
