Unlike flat washers, which are placed on both the bolt and nut side, spring washers only go on the nut side of the fastener to establish a bond. A spring washer offers axial flexibility that’s intended to prevent loosening of the fastener with which it’s paired.
Where should a spring washer be placed?
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.
Should you use a flat washer with 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.
Where does a spring washer go on a bolt?
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.

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.Which side of washer goes up?
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 used for?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.
Article first time published onWhat are star washers used for?
Star washers are a specific type of washer designed to increase locking force by resisting torque applied by the nut, preventing it from unscrewing or separating.
Are flat washers directional?
Yes, they are directional, based on the stamping.
Do spring washers work?
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. Junker originally showed in his work published in 1969 that these washers are ineffective in preventing loosening.
Can you put a washer on its side?
It’s recommended you always keep a washing machine in an upright position. Laying a washer on its side can cause the inner and outer tubs to bump against each other, which can loosen support pads or damage the suspension. It can also cause the tubs to move out of alignment and alter the way your unit works.

What is a spring lock washer?
Spring steel spring lock washers compress as the fastener is tightened and securely lock bolt or screw heads into place to prevent counterclockwise rotation from vibration. Spring steel construction offers resiliency.
Why washer is used in nut and bolt?
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. … To prevent loosening, several other types of washers are used.

Once the bolt is threaded into the hole, begin turning the head of the bolt using the appropriate sized wrench. Tighten the bolt down to the washer until the head contacts the washer.
Do I need washers for screws?
The primary purpose of most washers is to evenly distribute the load of the threaded fastener with which they are used. Threaded fasteners stress the material in which they are driven. Driving a screw into wood, for example, may cause the wood to crack around the surface. … Not all materials require the use of washers.
Which washer is used to prevent a bolt from backing out?
Split washers – also known as lock or helical spring washers – are one of the most common mechanical devices bike owners use for this purpose. In theory, the washer is squashed flat when the nut is tightened against mounting surface so that its sharp edges dig in to prevent the threaded fastener unwinding.
Can you stack flat washers?
It is not a good practice to stack washers in a fastener joint. Each stacked element acts like springs in series, consequently, fastener joint stiffness would be compromised.
What size washers are used for washer toss?
Contestants may use their own washers as long as each washer is at least 2 15/16″ in diameter and weighs 4 1/2 ounces or less. 3. SCORING: a) The first (closest) hole is 1 point, second (middle) hole is 3 points and the third (farthest) hole is 5 points.

Can you use two washers on a screw?
1 Answer. Slip the lock washer on the bolt, then slip the large washer on the bolt, then screw the bolt into place. The lock washer “bites” into the bolt head and into the large washer so that the two become connected. The large washer has a lot of friction against the bed post, so the bolt does not turn and back out.
Why is spring washer used?
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.
Why are washers directional?
They are intended to prevent a fastener from loosening. These are washers with serrations that extend radially (inward or outward) to bite into the surface of the component. By design, they are supposed to “dig in” to the bolt head/nut and the substrate to prevent the fastener from loosening.
Can spring washers be reused?
Damaged or worn washers should not be reused, as this can limit the performance of the wedge-locking effect and expose your bolted joints to loosening.
