What goes first lock washer or flat washer?
Ideally the lock washer goes into the threaded fastener first followed by the flat washer. This way the lock washer adds tension to the fastener assembly. It creates pressure on the bolt or nut (depending on where it is used) to prevent the assembly from loosening when it is exposed to vibration.
What is the difference between a lock washer and a flat 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.

Washers reduce the risk of such damage by evenly distributing the fastener’s load across the surface of the material.
When should you use a split lock washer?
Split ring washers use friction to prevent bolted joints from loosening. They feature a ring that has been split and twisted – creating two sharp edges. These washers are installed between the bolt head/nut and mating surface, the bolted joint is then tightened in the same way as an unsecured bolt.
How do you keep a nut from loosening?
Nylon or metal inserts inside a nut (sometimes called a “lock nut”) can add extra friction to prevent loosening. A related idea is to fit a spring inside the nut, which firmly grasps the bolt threads and is designed to move in the opposite direction of the nut if vibration or other forces cause it to unwind.
Can you use two lock washers?
a “Lock washer“, which is what those are called, it is suppose to be tightened so that they are fully compressed. Both tabs should be in line.

Put the washer directly underneath the nut. If you have more than one washer, you can put one next to the head of the bolt and one next to the nut. If you have a washer and a lock washer, put them both next to the nut, but make sure the lock washer is between the regular washer and the nut.
