Lock washers are placed between the bolt head, screw head or nut and the surface of anything that is being fastened. The main function of lock washers is to help bolts and screws retain their torque and prevent them from loosening.
Lock washers work by applying a spring force against the nut or bolt head. Different lock washers perform this function in slightly different ways, but the basic concept is to hold the nut and bolt in place. Some lock washers achieve this function by biting into the bolt and the nut with their ends
Lock washers are installed by putting a bolt or screw through the center of the washer, so that the washer is beneath the bolt or screw head or between the nut and the surface being fastened. Lock washers are used to keep screws and bolts from loosening, especially as a result of vibration or change
Self-locking nuts use either a pre-installed plastic insert or a chemical substance applied to the threads that, when initially tightened down, spreads in between the threads to create a more stable adhesive bond than the metal-to-metal connection of an ordinary nut and bolt. Locking nuts keep a thr
Lock nuts are typically used by engineers and mechanics to secure wheels on axles and threaded shafts. A nylon lock nut comes with a nylon insert that conforms to the threads of the screw on which it is placed. This causes the nylon lock nut to grip better against the threads and reduces the chances
Some different types of locks are padlocks, knob locks, lever-handle locks, dead bolts and furniture locks. These types of locks differ in the amount of security they offer and the locking purposes they serve.
Computers running Microsoft Windows can be locked at any time by holding down the Windows key on the keyboard and pressing L. The current user's password must then be entered to resume using the computer.
An ordinary nut with an ordinary washer, used to fasten a bolt on something that is subject to repetitive vibration -- say, a wheel axle or engine accessory -- would eventually vibrate loose. Lock washers and lock nuts prevent this from happening. Lock washers, when tightened to the required torque
Washers are an important part of using nuts and bolts, but not all washers are alike. Whether you should use flat washers or split washers depends on the materials involved and where the washer is placed. Understanding the difference between flat washers and lock washers is important for proper use.
Nylon lock nuts differ from a standard hex nut in that they have a nylon insert secured within the nut. The nylon insert is located in a tapered section located at the back of the nut. When you install the nylon lock nut onto a bolt or threaded stud, the nylon insert wraps around the threads and loc
