What is an encapsulated bolt?
The “micro-encapsulated screws” are factory bolts that have on them, a Loctite type of chemical (usually blue) that prevents bolts from getting loose in high vibration and shock applications.
What are nuts with built in washers called?
A flange nut is a nut that has a wide flange at one end that acts as an integrated washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface.
What type of washer prevents nuts and bolts 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.
Why are washers often used on nuts bolts?
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. Washers reduce the risk of such damage by evenly distributing the fastener’s load across the surface of the material.
How do you keep nuts from coming off bolts?
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.
Should I use a washer for the nut and bolt?
The washer helps prevent damage to the surface of the object being fastened. In most cases where the bolt is easier to turn, the bolt has a round head that will cause less damage anyway. For the same reason, lock washers always go on the nut side to stop the nut moving.
Are washers really necessary?
Most notably, washers protect the surface from damage during installation. They distribute the pressure and prevent the fastener from moving or corroding. Skipping on washers can dramatically reduce the lifespan of how your product is put together. Not just any washer will do for all applications.
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.
