A lock washer is designed to press into the surface of the nut and whatever is being fastened. Flat washers spread out the load of the tension to prevent pull through or bending whats being fastened, but makes lock washers useless.
Can you use a flat washer with a lock washer?
Lock washers are almost always used with a flat washer as well. The nut is also often smaller in profile than the bolt head. Not always, but often. The washer helps distribute the pressure that the nut places on the surface of the fastened objects.
Can you use a flat washer with a lock nut?
Flat washers may be used on either the bolt side, the nut side or both sides of the fastener.They may also be useful as spacers when a bolt may be a bit too long for the job. Lock washer use is a bit different as they are typically used on the nut side of the fastener.
When should flat washers be used?
Flat washers
This is particularly important if the contact area between a screw’s bearing surface and the object being fastened is small or if it’s made of a soft material, such as aluminum or resin. Since flat washers are generally manufactured by pressing metal, one side has rounded corners and one side has burrs.
Do you really need lock washers?
When are lock washers needed? Lock washers are needed when the fastener assembly is subject to vibration or wherever back off is considered an issue. When should I use washers with bolts? Always use a washer between the installation material and the nut.
What goes first washer or lock washer?
When used correctly, a lock washer will hold the nut or other threaded fastener in place. To help it accomplish this, put the lock washer on first, below the fastener. If your project calls for other washers or hardware elements, they should go on before the lock washer so that it can hold them in place.
What is the difference between a flat washer and a lock washer?
Flat and lock washers are two of the most common types of washers. A flat washer is a basic washer that’s flat on both sides. A lock washer is a semi-coiled washer that’s used to secure bolts in place.
What is the difference between a fender washer and a flat washer?
Fender Washers have a larger outside diameter as compared to the inside diameter. Therefore fender washers distribute the load to a relatively larger area compared to flat washers. Fender Washers have applications in automobiles, plumbing, sheet metal, electrical applications, attaching signboards, panels, and drywall.
What is the purpose of a lock washer?
Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.
What type of lock washer is best?
We found that the most effective anti-vibration solutions are anaerobic adhesives and mechanical washers. Overall, Nordlock washers were extremely effective. They’re as easy to install as any standard washerand easier to install than the next-best contender, the Loctite 2760 adhesive.
What is the purpose of a washer on a screw?
washer, machine component that is used in conjunction with a screw fastener such as a bolt and nut and that usually serves either to keep the screw from loosening or to distribute the load from the nut or bolt head over a larger area.
Are lock washers good?
They are still used on many applications in the belief that they will will “lock” the nut/bolt to the joint and prevent loosening. The body of evidence, based upon both experience and experimental results, is that they do not prevent loosening and can be shown to actually speed up the rate of loosening in many cases.
Which way does the flat side of a washer go?
There is no fixed rule about which side goes up and which goes down, but given the issue of bearing surface pressure mentioned above, it’s more effective to put the burred side facing down.
What are flat washers?
Flat washers
Also known as plain washers, their purpose is to distribute the fastener’s load while reducing heat and friction during the tightening process. They can also be used as spacers, as is common in industrial and domestic applications. Flat washers are also called on to provide electrical insulation.
Are spring and lock washers the same?
Washer types.Spring washers, which have axial flexibility and are used to prevent fastening or loosening due to vibrations. Locking washers, which prevent fastening or loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.
Which type of washer is used for locking the nut by bending the washer against the side of the nut?
tab washer
On assembly, a tab is bent against the component or sometimes into a hole in the component. Other tabs are then bent up against the correctly tightened nut. The deformation of the tab washer is such that it is intended to be used only once. The following types of Tab washers are used.

Do you need a lock washer with a nylon nut?
When you install the nylon lock nut onto a bolt or threaded stud, the nylon insert wraps around the threads and locks the nut in place. This gives a nylon lock nut a distinct advantage over a lock washer when the bolt or threaded stud is subject to vibration, as the nylon lock nut is unaffected by vibration.
