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.
