General Fastener Reference Guides. Product Sitemaps Clamp loads are based on 75% of the minimum proof loads for each grade and size. Once torque has been applied to a joint, an audit function measures exactly how tight that fastener was torqued. the recommended torque by the appropriate factor shown in the table. Torque is only an indirect indication of tension. Torque values are based on clean, dry threads. Values calculated using industry accepted formula T = KDP where T = torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load (lbs). THREAD: LOCKER. (Table IV from ref. For these reasons, it is not practical to provide a single bolt torque chart or … Because there are many variables that affect the torque-tension relationship, the only way to determine the correct torque is through experimentation under actual joint and assembly conditions. Grade 2 calculations only cover fasteners 1/4" - 3/4" in diameter up to 6" long. These estimated torque values are derived from the standard torque formula Torque = KDF utilizing a standard "free-spinning" nut (non-locknut) with a proof strength equal to or greater than the tensile strength of the bolt. Proof load, stress area, yield strength, and other data is based on IFI 7th Edition (2003) Technical Data N-68, SAE J429, ASTM A307, A325, A354, A449, and A490.
