Steel Tubes India are the leading manufacturer of high integrity special fasteners (e.g. bolts, set screws, stud-bolts, nuts and washers), meeting clients’ exacting demands for critical applications in hostile environments. Whether for offshore (buoyancy and petrochemical), seawater, pump, valve or nuclear, the demands for an exceptional service and supply is never ending. We believe manufacturing bolting in exotic materials is an art form and it is something we have perfected at Steel Tubes India

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.

Bolt Joint

The distinction between a bolt and a screw is usually unclear and misunderstood. There are several practical differences, but most have some degree of overlap between bolts and screws.

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.
