This allows for proper tightness so bolts won't loosen later. mm These formulae may be used for bolts outside the range of the tables overleaf. If higher property class fasteners are used, these should only be tightened to the strength of the original. The specific torque value should be determined based on the aluminum or brass material strength, fastener size, length of thread engagement, etc. Torque for bus bar lugs is specified by lug size. The accuracy of the tightening method, as well as the change in friction, needs to be accounted for in order not to over-tighten the fastener. It is a function of the materials' frictional characteristics, which are based on surface finish, coatings and so on. Tightening Torque Clamp Load (lbs.) Suggested torque amount. 8.0 in-lbs. Setting the correct torque on your torque wrench is critical to prevent under or over tightening of your bolts or nuts. Proper torque spec varies depending on the material, bolt grade or wether lubrication is used such as oil, wax, or anti-seize Always go to the manufacturer for proper torque specs if needed.
