A fastener with threads is called as bolt. https://www.fixingsmegastore.co.uk/help/metric-bolt-torques IFI-100 does not govern lock nuts above 1". Lightning Bolt & Supply has been servicing North America’s industrial fastener needs for over 25 years. M6 - M16: 800 M20 - M30: 830. at 100% of yield. Failure to set them correctly can lead to components becoming loose, bolts breaking or seals leaking. It is applicable, basically, to bolts, screws, studs and nuts made of carbon steel and alloy steel, whose mechanical properties are specified in ISO 898-1 , ISO 898-2 or ISO 898-6 , having ISO metric threads with thread sizes M3 to M39. Torque is the amount of force applied on the bolt. 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 dia.ins 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 SizeUNRC Torque (N•m) Inch Metric Size Nominal Tightening Torque Nominal Tightening Torque Size (In-Pounds) Size (N•m) 4 5 6 8 10 1/4 516 3/8 1/2 5/8 Inch-Button Head Metric-Button Head 8-15 30 65 125 200 360 1000 1750 M3 x 0.5 M4 x 0.7 M5 x 0.8 M6 x 1 M8 x 1.25 M10 x 1.5 M12 x 1.75 Bolting material: MPa: applied load: load applied to the nut no!
