The new FS®-E All-Steel Lock-Nuts Economic and Ultra-Light are the solution to all applications where light, safe and high temperature resistance are required.
The new lock-nuts offer optimum safety even under dynamic loads and thus are ideal for application in the automotive-, aerospace-, wind energy- and bridge building industry.
Due to their small width across flats, a further weight reduction has been achieved in the Ultra-Light version, which makes a valuable contribution to CO2-emission reduction.
The FS®-E All-Steel Lock-Nuts Economic and Ultra-Light are one-part all-steel locking systems. The innovative principle insures that the clearance commonly seen in traditional screwed connections is removed.
The tightening torque of the screw with FS®-E All-Steel Lock-Nut increases according to the adjusted clamping torque. The clamping torque of FS®-E All-Steel Lock-Nut is therefore added to the tightening torque of your fastening application.
It is comparable to the effect that can be observed between a nut and a bolt when a pre-stressed nut is tightened.
The clever thing about it is, that the locking effect continues working even when tightened. The flank surfaces operate like a pressure spring against the thread direction of the bolt. This results in an all around safety-effect comparable to the effect a brake caliper has in a disc brake.
The thread flanks of the bolt are enveloped on the whole 360° by the FS®-E All-Steel Lock-Nut. The FS®-E All-Steel Lock-Nut Economic and Ultra-Light are available with and without flange. Upon request they can also be supplied with movable flange or with FS®-UltraLock®-anti-rotation lock
