For torque specifications on balllscrew components refer to Ballscrew - Installation Tools and Torque Specifications. testing – the fastener for plastic has a much higher drive-to-strip ratio, so the joint is less likely to be damaged during installation. All calculations are for Coarse Thread Series (UNC). Torque has been converted into ft/lbs by dividing the result of the formula by 12 All calculations are for Coarse Thread Series (UNC). 2 gives a variety of friction coefficients.) Therefore, these suggested torque calculations are estimates and offered as a guide only. SAE ( inch ) Fastener Torque Specifications SAE ( inch ) Breakaway Torque [Static Torque, Off Torque, Removal Torque] The torque required to begin reverse rotation in a fastener that has not been seated. Lubricated refers to fasteners in the “As Received” condition, which is normally a light preservative oil coating on unplated fasteners and no oil coating on plated fasteners. For A307 Grade A, 75% of 36,000 PSI is utilized. A193 B7 uses 75% of the yield strength. Extreme caution should be used when using a formula for torque… For other applications or questions, email engineer@fastenal.com. Grade 5, F or higher nut: DRY. Most company has their Flange bolt torque tightening procedure that used during construction and operation of the plant. Bolt tightening sequence or torque sequence is defined in the torque tightening procedure. For other applications or questions, e-mail engineer@fastenal.com. That point of movement is "breakaway torque." John Deere Metric Bolt & Cap Screw Torque Values. After being tightened, and torque is applied, there is a point when the fastener begins to move again. Torque is only an indirect indication of tension. Grade 2 calculations only cover fasteners 1 ⁄ 4 “- 3 ⁄ 4 ” in diameter up to 6″ long; for longer fasteners the torque is reduced significantly. In the case of bolts and nuts, this elastic deformation between the bolt head and the nut is critical in order to create tension or clamping force to hold the joint together. The standard screw has a safety margin of only 3.5 lbs.in. In addition, a proper bolt torque value can be inconsistent from fastener-to-fastener due to several factors including variations in material, coatings, surface finishes, fit tolerances, installation method, etc. For longer fasteners, the torque is reduced significantly.

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. Thread pitch is the distance between threads expressed in mm. Values calculated using industry accepted formula T = KDP where T = torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load (lbs). Note: The chosen seating torque was 65% of the failure torque, based on testing. D = Nominal Diameter F = Clamp Load For J429 Grade 5 and 8, FNL Grade 9, A574, Class 4.6, 8.8, 10.9 and 12.9, the clamp loads are listed at 75% of the proof loads specified by the standard.

There are many variables in the torque-tension relationship. We have the charts to help you identify the many different types of bolts and screws for just about any project. Extreme caution should be used when using a formula for torque/tension relationships. Grade 2 calculations only cover fasteners 1/4" - 3/4" in diameter up to 6" long. Torque applifast.com Steel Grade SAE 5 SAE 8 Socket Head Cap Screws Property Class 8.8 10.9 12.9 Socket Head Cap Screw Torque in Pound Foot or (Pound Inch) Torque in Newton Meter - Nm Lubed means cleaned, dry bolts, lubricated with standard medium viscosity machine oil. pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts (as received) = .20. There is no torque difference for fine or coarse threads. The special fastener for plastic has a safety margin of 12 lbs.in. A M30-12.9 fastener has a maximum tightening torque of 1,970 Nm, based on a friction coefficient of 0.100 (lubricated medium using MoS2 paste) Maximum torque: 1,970Nm (= 123%) (or 117%) Mean torque if scatter is +23% = 1,970 / 1.23 = 1,602 Nm Flange joints are torque tight with the help of a torque wrench (Manual or hydronic wrench). All rights reserved. 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. If you do employ the torque angle method, it's best to begin calibrating rotation from some small measured torque rather than the first point of contact with the work face. Torque has been converted into ft/lbs by dividing the result of the formula by 12 All calculations are for Coarse Thread Series (UNC). Lubricate all contact areas of the bolts and washers. For these reasons, it is not practical to provide a single bolt torque chart or … Fastenal has used reliable sources and testing to determine these values, there are many variables that will effect the results and the use of this information is at sole risk of the user. Since calculated torque values are a function of the friction coefficients between mating threads and between the bolthead or nut and its mating surface, it is vitally important that the torque table values used are adjusted to reflect any differences in friction coefficients between those used to calculate the table and t… Click here to download a printable rod bolt stretch monitoring chart Install fastener hand tight.
