Hex cap nuts are a finished hex nut with a dome that covers the threaded end of a screw or rod from protruding through the end of a nut. Cap nuts rounded dome is more then one times the size of a hex nut and is made to give a finished clean look. This is also to prevent scrapes and cuts when rubbed. Metric finish nuts are a type of fasteners with a threaded hole coarse or fine thread that are used for fastening to a hex cap bolt or socket screw or when mechanically joining materials together.The two parts are kept together by a slight stretch of the threads as the nut and bolt are torqued and pressure is applied to the bolt threads. Also a split ring lock washer may be used to lock the nut in place. Finish nuts are also used with flat and fender washers. Metric jam nut is a thinner low profile nut about half the size of a standard finish nut and is used as a locknut where it is jammed against a finish nut to lock the two nuts in place. Two nuts can be locked together free style, Jam nuts are also used where lower profile nuts are required in tight areas. For a jam nut to stay in place, both nuts must be torqued equally.
Hex flange nuts have a wide flange that is integral non spinning washer that distributes pressure of the nut flange over a larger area of the surface. Flange nuts have serrations to lock the nut in place and to prevent back-off or loosening by vibration. Please Note: the serrations will scratch the surface. There are non serrated flange nuts but they are not widely available. A Keps nut, also called a K-nut, external tooth lock nut, or washer nut, is a nut with an attached, free-spinning washer. It is used to make assembly faster, easier and more convenient. Common washer types are star-type lock washers, conical, and flat washers.Metric nylon lock nuts has a nylon polymer insert to prevent back-off by vibration. Also known as a elastic stop nut what has a plastic insert that becomes threaded as the screw to bolt is threaded onto to the nut. This is called deforming the elastic insert! The nylon insert locks the nut to the screw by forcing the bottom face of the screw to the top face of the nut threads increasing the friction at both ends and applies force against the screw or bolt. Nylon lock nuts are not made to be back-off after being applied which creates cross threading of nylon insert. This will create lock-up. Metric wing nuts are used to screw on and off without tools for a quick installation or release. These nuts have a threaded center hole with two wings.
