The use and effectiveness of spring lock washers has been debated, with some publications [10] [who?] advising against their use on the grounds that, when tight, the washer is flat against the substrate and gives no more resistance to rotation than a normal washer at the same torque. A 1990 NASA manual states "In summary, a lockwasher of this ...
A bottle of Loctite thread-locking fluid Bolts with thread-locking fluid applied. Thread-locking fluid or threadlocker is a single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion.
Use of lockwashers on soft materials like plastic is only recommended when the lock washer is placed between the screw head and a flat washer. A lock washer (of any type) bearing directly onto a soft surface is quickly made pointless by the soft material's creep or deformation under pressure.
High-efficiency washers use 20% to 60% of the detergent, water, and energy of "standard" commonly-used top-loader washers. They usually take somewhat longer (20–110 minutes) to wash a load, but are often computer controlled with additional sensors, to adapt the wash cycle to the needs of each load.
Belleville washer. A Belleville washer, also known as a coned-disc spring, [1] conical spring washer, [2] disc spring, Belleville spring or cupped spring washer, is a conical shell which can be loaded along its axis either statically or dynamically. A Belleville washer is a type of spring shaped like a washer.
In normal use, a nut-and-bolt joint holds together because the bolt is under a constant tensile stress called the preload.The preload pulls the nut threads against the bolt threads, and the nut face against the bearing surface, with a constant force, so that the nut cannot rotate without overcoming the friction between these surfaces.

The fastener serves the functions of both a lock washer and a nut.As the fastener is tightened in the nut the prongs are drawn inward until they exert pressure on the root of the thread on the fastener.
