Reliable Steel Distributors is a specialized manufacturer of high quality bolts  in India . A bolt is a type of fastener, usually made from metal, that commonly comprises a head at one end, a chamfer at the other, and a shaft characterised by an external helical ridge known as a ‘thread’. Bolts are typically used to hold materials or objects together, or to position objects

Bolts are fasteners that require a nut or pre-tapped hole to be installed. Screws use their threads to provide their own holding power. The terms in the industry are commonly mixed so sometimes you will see something that is called a screw or a bolt that is actually the opposite.

Carriage Bolts

Also known as a “coach” bolt, has a domed or countersunk head. The square section under the head grips into the part being fastened preventing the bolt from turning when the nut is tightened.

Hex Head Bolts

Hex tap bolts, hex cap screws, trim head hex cap screws, and hex serrated flange bolts fall under this category. They share a hexagonal head and are driven with a wrench. Referred to as both bolts and screws.

Machine Screws

A machine screw is a screw or bolt with a flat point. Available in a variety of drive types and heads, they fit a wide variety of applications. Often driven into tapped holes. Used with nuts and washers, also known as “stove bolts” or “stovers”.

Shoulder Bolts

Shoulder bolts (also known as shoulder screws or stripper bolts) are machine screws with a shoulder between the thread of the screw and the head of the part. Once installed, the non-threaded portion extends out of the surface of the application site, allowing the bolts to act as dowels or shafts for moving parts. They can be installed by hand or with a socket (Allen) driver.

Socket Cap Screws

Socket cap screws are available in button socket, button flange socket head, flat socket, and socket cap. Driven with a socket wrench or a hex Allen key. The term socket head cap screw typically refers to a type of threaded fastener whose head diameter is nominally 1.5 times or more than that of the screw shank diameter.

Square Head Bolts

Set screws are most often headless (aka blind), meaning that the screw is fully threaded and has no head. A blind set screw, known in UK as a grub screw, is almost always driven with an internal wrenching drive, such as a hex Allen key. Socket set screws are installed in threaded holes or inserts.

Bolts are headed, externally threaded fasteners used to keep two objects, often metal or wood, in a fixed position relative to one another. Unlike screws, which cut their own threads, bolts pair with the internal threads of nuts to stay in place and ensure the desired level of tension in the bolted joint. The use of nuts aids in disassembly and reassembly. In addition, bolts generally have a greater load bearing capacity than screws but lack a tapered shaft. The head style of the bolt determines the tool required for tightening and loosening. Bolts are responsible for holding together everything from furniture to machinery to bridges.

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.
