Projection Weld Screws & Studs



Benefits, depending on the projection weld stud used:

  • Are used in heavy duty applications
  • Prevents leaking and contamination from foreign substances
  • Large weld area provides high welding strength
  • Can be welded to or through base material
  • Appearance based welding possible
  • Typically a plain finish (may contain light oil coating)

Projection weld studs are available with either inch or metric threads. They are generally made using a weldable steel grade though stainless and aluminum screws are also available.

Projection Weld Stud Types

Under head or on top of the head projection weld studs provide a larger weld area for additional strength. Under head projection studs are welded through a preexisting hole in the steel base. Over head projections allow for welding to a base material without using any hole. These types of weld screws are often used for appearance based welding as the stud will not go through the material, thus leaving one side unmarred.

Ring projection weld studs have a 360 degree ring that is used to prevent leaking or contamination. This type of fastener is welded all around the periphery of the head keeping dirt, oil, gas, moisture, and other substances from getting in or out through the hole. The ring fastener is ideal for perforated, mesh, or cross-wire base material. It is also available as a heat treated weld stud.

Projection weld studs can be used in heavy duty applications in a variety of industrial and commercial applications. These weld screws are available as either a bare metal finish or plated finish.
