A washer is a thin plate with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to Brinelling after the torque is applied.

We can supply round , square and rectangular washers as per various international specification and as per customer drawings.

A stud bolt is a mechanical un-headed fasteners with a fully or partially threaded body which, with additional hardware (nut ) , can secure two adjacent objects or surfaces. Unlike many types of bolts, this particular style is not driven into an object or surface, but passed completely through.

Nuts or flanges on either end of the bolt then hold the two objects together.

The ability to adjust the tightness is a key element lending to the popularity of the stud bolt in a variety of applications. Engineering, motor, automotive, petrochemical and nuclear industries all make use of these bolts which can be specially contoured to distribute stress evenly, reducing the occurrence of breakages.

it can also be used as an anchor bolt in civil and architectural engineering. This is accomplished through cast-in-place techniques that insert one end of the rod into setting concrete. The threaded end provides added resistance to pullout and machinery or other objects may be fastened to the exposed threading with a single nut or flange.

The materials used for stud bolts and corresponding nuts and flanges depend largely on the use, though steel alloys are the industry standard. Zinc,PTFE & Fluoropolymer coatings are common finishes that enhance the corrosion and environmental resistance of steel.

We Manufacturers stud bolts for general purpose , flange joints in piping systems and for oil field applications in high pressure / high temperature & low temperature services

Anchor bolts are generally embedded in concrete and used to anchor columns or other supports to a foundation or for construction and in securing traffic signal poles, are commonly used because they provide a strong fastening with minimal room for error.,

These bolts are set into wet concrete headfirst the threaded end of the bolt is attached to a component which anchors the bolt to its intended external load but once it has hardened, and once the concrete has hardened the bolt is very secure and able to hold a large amount of tension..

Are widely used in building construction, highway systems, electrical towers, power treatments and marine industries, anchor bolts are an essential method of securing large components to a solid foundation to ensure against structural failure or damage.Used in many large buildings to connect the foundations to the walls for improved earthquake resistance,

We manufactures Anchor bolts in various shapes and sizes as per customer drawings with or with out sleeves as per end user requirements.
