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 order do washers go in?
TYPICAL installation is screw, materials, flat washer, lock washer, nut. But for some reason, the engineer requires the assembly be in the order of screw, lock washer, flat washer, materials, nut. And that is the sequence you should follow.
Do washers go above or below?
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.
Where should a lock washer go?
Place the lock washer under the threaded fastener and ensure that it has a snug fit. If using a lock washer with teeth, make sure they will engage with the appropriate surfaces. If they don’t, swap out the washer for the appropriate one.
Do washers go on both sides?
Washers can go both sides, but the primary function of a washer would be to stop vibration from loosening the nut, so there’s your first choice (with a slightly springy ‘split’ washer being a top choice) but also some nuts have locking technology… As far as we know, the washers are attached to the Nut side.
Does the spring washer go on first?
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.
Does the washer or lock washer go on first?
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 washers directional?
The general rule of thumb is that the flat side goes to the material, while the rounded side goes against the bolt or nut.
What does a stop nut do?
Lock Nuts with Nylon Inserts
Nylon insert lock nuts—also known as nylon nuts and stop nuts—are a prevailing torque, locking nut that resists loosening caused by vibration and normal use.
What side does the washer and dryer go on?
The washer is on the left and the dryer is on the right in laundry machines. The lid is on either the rear or left side.
Where do washers go on table legs?
NB: It’s important that the washers are put onto the nut/bolt in the right order, so always make sure that you put the spring washer (the one that’s split to give it more flexibility) on first and the flat washer on second. Load the spring washer onto the bolt first, and the flat washer second.
Why use a washer with a screw?
Load Distribution
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.
Where do spring washers and flat washers go?
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.
Should you use a lock washer with a lock nut?
Locking Washers
Place the lock washer between the nut and the work surface if using a nut-and-bolt configuration, or between the fastener head and the work surface if using a tapped hole configuration. In other words, the bolt goes straight into the hole and doesn’t poke out the other end, so no nut is used.
When should you not use a washing machine?
Washers should always be used with nuts and most bolts , one exception is coach bolts that inset into a square hole in metal or lock into a hole in wood and only need a washer on the nut end .
What is the difference between a flat washer and a spring washer?
Plain washers are flat, whereas spring washers are curved. For most applications, plain washers are typically used. For machines and objects that vibrate, spring washers are recommended. Spring washers are unique because they provide an axial load that counters vibrations and, thus, prevents fasteners from loosening.
Are spring washers necessary?
Washers are not always necessary but it is common practice to use them anyway. How do spring washers work? Spring washers add tension to a fastener assembly and are used to absorb a shock or vibrations.
Should a flat washer be used with a lock washer?
It is important to note that any of these locking washers should NOT be used with flat washers, and if used with a bolt and nut joint, they should be on both ends. Rotational loosening caused by vibration will occur at the bearing surface with the least amount of friction, so flat washers should be avoided.
Do washers go flat side down?
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.
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.
Are crush washers directional?
Direction of crush washer is one of the most common questions, the correct answer is that the contact diameter of the washer needs to be the same or smaller that the surface it mates against, in some cases that’s cone forward, in others it’s cone towards shooter, and in others it doesn’t actually matter.
