Left Threaded Bolts Reverse Mirror Alloy Metal Hex Socket Inserts
The left threaded bolts are the bolts have reversed thread. Reverse threads, or a reverse threaded bolt, are used from time to time when a normally threaded bolt or nut might work itself loose. All it means is that instead of turning it clockwise (righty) to tighten, you turn it counter-clockwise (lefty). To loosen a reverse threaded bolt, you turn it clockwise. Ever Hardware provides the custom-made left threaded bolts and customizable packaging.
The defining distinction, per Machinery’s Handbook, is in their intended purpose: Bolts are for the assembly of two unthreaded components, with the aid of a nut. Screws in contrast are used with components, at least one of which contains its own internal thread, which even may be formed by the installation of the screw itself. Many threaded fasteners can be described as either screws or bolts, depending on how they are used.
Bolts are often used to make a bolted joint. This is a combination of the nut applying an axial clamping force and also the shank of the bolt acting as a dowel, pinning the joint against sideways shear forces. For this reason, many bolts have a plain unthreaded shank as this makes for a better, stronger dowel. The presence of the unthreaded shank has often been given as characteristic of bolts vs. screws, but this is incidental to its use, rather than defining.
Where a fastener forms its own thread in the component being fastened, it is called a screw. This is most obviously so when the thread is tapered (i.e. traditional wood screws), precluding the use of a nut, or when a sheet metal screw or other thread-forming screw is used.
