Where do you put a spring washer?

Where do you put a spring washer?

Where does a spring washer locate? Spring washers should be used on the nut side of the fastener. If an additional washer is required to spread the load (as in our image above) it should be used between the spring washer and the mounting surface, i.e. the spring washer should be positioned next to the nut.

What is the difference between a flat washer and a spring washer?

Plain and spring washers are both used to distribute the load of a fastener. The difference lies in their shape. Plain washers are flat, whereas spring washers are curved. ... Spring washers are unique because they provide an axial load that counters vibrations and, thus, prevents fasteners from loosening.

What goes first washer or spring washer?

Method 1 of 3: 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.

Are spring washers effective?

Helical spring lock washers have been in use for well over 100 years. ... Junker originally showed in his work published in 1969 that these washers are ineffective in preventing loosening. Joints containing these washers have come loose resulting in structural failure leading to both material and human loss.

What is the point of a spring washer?

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.

Should you use a flat washer with a spring washer?

The order should be bolt head, flat washer, materials being clamped, flat washer, spring washer, nut. If you only have one flat washer per bolt, and if the material next to the bolt head is sufficiently hard to resist deformation, then the one flat washer should be on the nut side.

What is the purpose of a spring washer?

Spring washers, also called disc springs or conical washers, use spring loads to create axial flexibility. This counteracts settlements and maintains an initial level of preload. The washers are installed between the bolt head/nut and the mating surface.

Should a flat washer be used with a spring washer?

The order should be bolt head, flat washer, materials being clamped, flat washer, spring washer, nut. If you only have one flat washer per bolt, and if the material next to the bolt head is sufficiently hard to resist deformation, then the one flat washer should be on the nut side.

What is a spring washer used for?

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.

Does the washer go on the bolt or nut side?

If there is only one washer used with a nut/bolt, it usually goes on the nut side. The nut in most circumstances is more movable, and is more commonly turned to tighten the assembly. The washer helps prevent damage to the surface of the object being fastened.

What is the purpose of a spring washer?

• Spring washers are specifically designed to provide a compensating spring force and sustain a load or absorb a shock. Many design variations have evolved to best serve one or the other of these two basic functions or to optimize both functions in a single part within specific I.D./O.D. limits.

What is a spring washer used for?

• Spring washers are used in mechanical assemblies where fasteners might be loosened by vibration. These washers provide a constant pressure on the bolt and nut, keeping them tensioned and tight.

How does a spring washer work?

• Spring washers are typically used in applications where assemblies need a part to take up play, eliminate rattle, maintain assembly tension, compensate for expansion or contraction in materials after assembly, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.

What is a spring lock washer?

• Spring action lock washers include split (helical spring), which are also called spring washers. These washers, placed under the nut or screw head, compress as the fastener is tightened and the spring-back tension deters loosening.
