ANSI ML15AL M10 to M25 Seismic Wedge Anchors

Shear Connector Weld Studs are unthreaded with an upset head. Designed to interconnect the concrete slab to the load bearing steel beams. Because of the inter connection or composite construction resists shear loading between the concrete and steel beams. Meets with AWS and all other applicable specifications. Used in all types of concrete connections. They can be welded to flat or vertical surfaces, or to the inside or outside of an angle.

Material – Low carbon steel, ASTM A29, 1010-1020. Also available in a weldable stainless steel. Type 302 is the most commonly used. Other grades available on request. Please contact us for your specific needs.

Length: Length listed is before weld. Stud diameters less than 5/8” will be approximately 1/8” shorter after weld – Stud diameters 5/8” – 3/4” will be approximately 3/16” shorter – Stud diameters 1” will be approximately 1/4” shorter after weld.

What Are Shear Studs?

Definition of Shear Studs in Construction

Shear studs refer to the installation of steel pins or grommets, that extend out of the top flange of a steel support beam. Normally the shear studs are welded, with a spot welder, after the metal deck is installed over the supporting structural steel. The spot welder will burn through the metal deck and attach the shear stud directly to the top of the steel beam.

The purpose of the shear stud is to provide a structural connection between the poured in place concrete slab and the structural steel. This structural connection distributes any shear forces that the structure may incur. Without the shear studs in place, there is a slip plane between the concrete slab, the metal deck and the structural steel framework of the project. The structural engineer will determine, which beams will have the shear studs, the size of the studs as well as the number of studs to be installed. There are specialized subcontractors that will install the shear studs. The test for the shear studs integrity is simply striking the side of the shear stud with an iron mallet. This will ensure that the stud has been properly welded to the beam, if not, the stud will simply break off at the point of intersection with the steel beam. The stud will have failed due to a shear force.
