Tips For Using Weld Stud Concrete Anchors

There are several different terms that are commonly used for weld stud concrete anchors. They may be listed as headed anchor studs, headed stud anchors or sometimes as just anchor studs, although there are both headed and non-headed options in anchor studs.

Regardless of the specific term used, the defining part of weld stud concrete anchors is the head. To those unfamiliar with the look, these appear to be a non-threaded bolt that has a slight tip or protrusion at the base of the shank. They can be welded to a flat surface, but also to the heel or fillet of an angle.

This makes these headed anchors a very versatile product. They are used widely in bridge construction to hold the steel girders and the concrete slabs in place. They are also used in the construction of buildings made of composite materials, particularly concrete and steel.

Order Tips

If you are ordering weld stud concrete anchors, it will be important to specific to the supplier if there is a requirement for flat surfaces or to the inside or outside of an angle. This is not as much of an issue with the actual stud anchor but rather with the type of ferrule that is used.

Length Measurement

Keep in mind that the measurements provided by weld stud companies will be the actual measurement of the stud weld before the welding process. In other words, it includes the measurement from the top of the head to the bottom of the base, which includes the small protrusion that is melted in the process.

The final welded length of the weld stud will be stipulated by the manufacturer. It will be important to consider this when ordering. Typically, the difference is about one-eighth of an inch for half inch diameter studs and slightly more at three-sixteenths for those five-eighths in diameter.
