Jan 30, 2021PCC-1 published Table O-3.2-1 Reference Values (Target Torque Index) for Calculating Target Torque Values for Low-Alloy Bolting Based on Unit Prestress of 1 ksi (root area) (Inch Series Threads). This was done to ensure you can use it to determine and adjust to stainless steel fasteners that have a lower tensile strength.(plate) Bolt Torque Calculator(steel) This value is your bridge resistance. Typical Futek sensors have a bridge resistance of 350, 700 or 1000 Ohms. Length torque values for a2 K Factor is a torque coefficient between bolt and receptacle.

Accepted formulae relating torque and tension,based on many tests are:-M =P x D 60 or for metric sizes:-M =P x D 5000 These formulae may be used for bolts outside the range of the tables, M =torque lbf.ft P =bolt tension lbf D =bolt dias M =torque N.m P =bolt tension Newtons D =bolt dia.mm Force Flow lbf x 4.45 = N l/s x 2.119 = cu.ft/min(plate) Rubber pad mount bolt torque valueMay 18, 2010stainless screws into aluminum (pt II)Apr 21, 2010Plastic Screws Recommended TorqueJun 18, 2008Plastics thread seating torqueJun 21, 2004See more resultsSuggested Assembly Torque Values - CopperState(steel) Suggested Assembly Torque Values The tapped hole or nut must have an equal or greater proof load than the stud's minimum ultimate tensile strength.

There is no torque difference for fine or coarse threads. Torque values are based on clean, dry threads. Reduce value by 10% if threads torque values for a2
Maximum values unless otherwise stated. Types A2 and A4 may contain up to a maximum of 4% copper. The selection of steel grades within a group is the prerogative of the manufacturer, unless the purchaser has specified particular steels to ISO or national standards.(plate) Stainless screw to Aluminum torque values - Mechanical torque values for a2(steel) Nov 13, 2003All sorts of stress values are quoted for this material. I used 55ksi because a local vendor quoted it for his stainless steel socket head cap screws, and this was the lowest value I found. Metric cap screws in stainless are usually supposed to be A2 stainless with a tensile strength (ultimate?) of 800N/mm^2 (~115ksi).(plate) Stud Bolts - Bolting Torque Tables - Table 2A - Cold torque values for a2(steel) T = Torque value, (ft-lbs) F = Bolt pre-load, (lbs) k = Nut Factor based on lubricant used d = Nominal bolt diameter, (in.)

Once you are sure of the size and material of your bolts you can look up the torque values. When I Googled torque values for bolts made from A2 70 stainless, in M6 size, it was 77.0 in. lbs. dry, or 69.3 in. lbs. lubricated. Lubrication is yet another variable that can make a difference.(plate) What is the torque for a 8mm bolt? - FindAnyAnswer(steel) Apr 26, 2020The most common grading system used for bolts in the U.S. is the SAE system, but you can find metric grading systems as well. There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9.Each grade has a specific bolt strength.(plate) mechanical engineering - Optimal tightening torque for a torque values for a2(steel) As in the title, I need some indication about the optimal tightening torque to choose when screwing in a SS screw (A2-70, say) into an aluminium threaded hole. In particular, I am concerned with metrical dimensions (M8, M10 and M12).
