K Factor: advanced users only: Help. For mixed metals, use the torque of the lower of the two metals Torque range is normally calculated +/- 10%. DIN 7991 or ISO 10642 property classes 8.8 and 10.9. US $21.63-$24.51 / Set. lbs.) For brass, use 70% of the torque value of steel. K Factor is a torque coefficient between bolt and receptacle. Torque Settings Suggested Starting Values The below estimated torque calculations are only offered as a guide. 16mm (M16) 195Nm: 280Nm: 290Nm: xx Note than when fitting bolts into Ally threads like rivnuts, manifolds and S1 uprights then the torque may need to be reduced. 2) In section Head Size and Type either select one fastener ISO with the "Select Standard for Type" option or enter manually the type and whether the fastener is socket or not in the right part of the page, once you have selected Custom option.. 3) Enter strength class of the fastener. The importance of correct bolt tightening cannot be over emphasized. lbs.) For brass, use 70% of the torque value of steel. Print this page . μ th = Thread friction coefficient μ h = Under head friction coefficient 1 N = 0.225 lb 1 Nm = 0.738 ft-lb. The torque figures quoted are approximate figures and are available to fasteners in the self-colour condition only. Locate machine parts. Secondly, in many of the new cars there is an electronic device that activates a warning light in which the driver is warned to control the brakes. Approximately 90% of the applied torque is employed in overcoming friction, 50% at the bearing face of the nut and 40% between the mating threads. 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 Torque Values and Friction Coefficient - All Metal Self Locking Nuts - Where Torque tightening equipment is used, account should be taken of the additional torque required to overcome the resistance of the prevailing torque locking nut. Print this page . lbs.) lbs. The bolting standard will define whether the torque value is for a dry or lubricated stud/bolt thread. 4.1 (69) … M16 x 2.00 161 121 230 172 269 202 120,350 psi ... Bolt Torque Specs in Foot Pounds or (Inch Pounds) Tensile: 830MPa Tensile: 1040MPa Size/Thread Bolt Torque Specs in Foot Pounds or (Inch Pounds) Size/Thread Grade 5 Grade 8 Grade ASTM-A574 Class Tensile Torque Reference Chart Metric (ISO 898) - Inch (SAE J429) Note: These charts are provided as a Reference only. The only way to determine an exact torque value is by actual application. Spring strut/Wheel spindle . Bolt Diameter (mm) Recommended Torque (Nm) Class 8.8 Doing a bolt up to a specific torque should set the tension in the bolt to appeoximately 85% of the prrof load given in the table. USED - Component that was in a running engine. Resolution may require a signed user agreement, verification on internal training, legal or executive personnel engagement. Preloads and tightening torque for Metric ISO countersunk head steel screws with hexagon socket head or similar heads. Setting the correct torque on your torque wrench is critical to prevent under or over tightening of your bolts or nuts. They should be used on all fasteners unless otherwise specified. The chart below is for torque settings on 4.8, 8.8, 9.8, 10.9 and 12.9 metric steel bolts. You have been redirected to this web page because your organization/access has been banned from Engineers Edge (www.engineersedge.com). 2nd step, 90° Rear sub-frame in body (M12) 100 Nm . Friday, 08-Jan-2021 22:07:23 EST, User Remote Address (IP): This, and all subsequent torquing, of bolts should be undertaken at ambient temperature. Tightening Torque Clamp Load (lbs.) The torque value is dependent on the friction between the threads of stud bolt and nut head, this friction can be affected by the application of a lubricant or any plating (e.g. Torque Diameter Pitch (mm) kN Nm M5 0.80 7.67 8 M6 1.00 10.9 13 M8 1.25 19.8 32 M10 1.50 31.3 63 M12 1.75 45.5 109 M14 2.00 62.1 174 M16 2.00 84.5 270 M18 2.50 103 371 M20 2.50 132 528 M22 2.50 164 722 M24 3.00 190 914 M27 3.00 248 1339 M30 3.50 … It can therefore be seen that only something in the order of 10% effort is employed inducing axial load in the bolt. 292: 489: Grade 10.9 (below) M22. Determining the correct torque can however present problems. Torque Settings Suggested Starting Values The below estimated torque calculations are only offered as a guide. to BMW N 600 02.0 Applicable range for tightening torques, refer to extract from company standard BMW N 600 02.0 M16 thread M16 8.8 200 Nm (ft. NOTE: Overtorquing rod bolts 20% places stress on the threads in a NEW aluminum rod. All correspondence must be done by email.
