Safe: Plastic Banding Roll can keep 5% tightening force with loosing in a long time. [...] WebbNormally the force required to untighten is checked, to know that the bolt is safe. Untightening torque is often not linear to the tightening torque; however, this is a somewhat more accurate and a reliable method compared to torque check inspections. It can seem a bit ironic to have to untighten (completely loosen) a bolt to know if it is safe.

WebbP breakaway = F f = μN = μ 3 F i where F i is the initial tightening load. Assuming a typical friction coefficient of 0.35 and an initial tightening force of 90% proof then P breakaway = 50 kN = 0.35 x 3 ( 0.9 x A s x 650 ) ; A s = 81 mm 2 ie. M12 x 1.75 bolts are called for. Free Body # 2 - side view. WebbThe screw thread should be on the bottom. There is also nothing that really holds the post assembly together with other than the initial force created when tightening the post against the framing. For that reason, we have seen many jack post failures when they lose their initial tightening force.
