Torque in Pound Foot or (Pound Inch) Torque in Newton Meter - Nm Lubed means cleaned, dry bolts, lubricated with standard medium viscosity machine oil. Where the proof load is not quoted in the specification this has been taken as 95% of the yield stress. Now you know the torque required to achieve the ultimate shear strength of this specific bolt. Lubed means cleaned, dry bolts, lubricated with standard medium viscosity machine oil. Do It Right, Use This Torque Guide.

Title: Metric Bolts, Screws & Nuts: Tightening Torques Author: Fastener Mart Created Date: 8/12/2006 10:22:23 PM Print this page . Actually I am going to carry out planned maintenance on equipment and as per job plan I am given tightening torque table in which data for brass to brass is not available.
The torques are theoretically calculated values depending on the friction coëfficient chosen and based on a pre-load, utilizing 90% of the minimum 0,2% proof stress during assembly. Don't Over Tighten Nuts & Bolts. Bolt Diameter x Pitch Thread Stress Area mm 2 *When μ = 0.10 Results in: *When μ = 0.14 Results in: Tightening Torque Nm Pre-load kN Tightening Torque Nm Don't Over Tighten Nuts & Bolts. The torque figures quoted have been based on a theoretical bolt load equal to 85% of the proof load of the bolting material. Do It Right, Use This Torque Guide. It, too, can be stored in a wide range of temperatures.

Grade 2, 5, and 8 values are for slightly lubricated bolts. To convert from N-m to ft-lbs, multiply N-m by 0.7375. The best way to do this is to set the wrench to a low setting and flex or click the head 10 times in the same direction (in the clockwise position). Torque Tightening Values for Structural Steel Bolts Below is a list of the recommended tightening torques for 12.9 / 10.9 / 8.8 zinc plated finish bolts. Add the nut and torque slowly, adding force increments until the bolt thread is sheared, or the threads shear.
