The locking washer with gripping teeth is used for locking fastening components which are rotated. The locking washer has radial slots on its outer circumference or alternatively slots can be arranged on the inner circumference of the washer. Washer with outside teeth is used for locking head of bolts. Any tendency for the bolt head to rotate results in firmer gripping of the bolt head by the washer teeth. A washer of this type can be used for securing threaded parts to housing bores.

This application claims benefit of and priority to UK Patent Application No. GB1420508.2 filed Nov. 18, 2014.This invention relates to apparatus for masking a nut plate during painting of an aircraft part containing the nut plate.Various parts of aircraft, for example parts of aircraft wings and bodies are secured together by devices known as nut plates. Usually the parts are secured together by a large number of the nut plates which are located around the periphery of parts to be secured together. Often there is a slight misalignment between a hole in a first part and a hole in a second part which is placed on top of the first part. To allow for this misalignment, the nut plates take the form of a T-nut having a part located in a channel. A clip which is like a circlip is located in a groove in the channel, and grips the part of the T-nut in the channel. The T-nut moves within the clip, and thus the T-nut is able to move back and forth in the channel as may be required to compensate for the misalignment. When the aircraft parts are painted, for example sprayed, paint tends to get on the nut plate and secure it in position. It is then necessary to break the nut plate free from the dried paint so that the nut plate ...

A thin-walled sleeve made of plastically deformable material and having a wall thickness smaller than the height of the annular space is arranged in the annular space and then is plastically deformed to fill the annular space during tightening of the nut. The sleeve material plastically flows into the interstitial spaces between the tooth surfaces of the machine element and the journal, thereby securing the machine element against rotation relative to the journal.
