Custom Electrical Fixing Bolts Flat Locked Auto Parts Electrical Conical Screw

Custom electrical fixing bolts are made of stainless steel or aluminum that used for antenna or aerial accessories. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. Aluminum is a relatively soft, durable, lightweight, ductile, and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Ever Hardware provides custom-made fasteners and customizable packaging.

A bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws.
The distinction between a bolt and a screw is unclear and commonly misunderstood. There are several practical differences, but most have some degree of overlap between bolts and screws.
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.
