MASON Shear Connectors / Shear Studs

Headed studs (automatically welded) are used as shear connectors/shear studs. Automatically welded headed studs are the only type of shear connector that can be attached through profiled steel sheeting.

The composite beam application consists of three elements including a steel beam, MASON shear connectors/shear studs welded to the beam through the deck with an Automatic Stud Welder, and a concrete slab.

The interconnection between the steel beam and concrete slab of a composite beam enables the two components to act together as a single structural member, and it is broadly referred to as the “shear connection”. “Shear Connection” comprises the shear connectors, slab concrete, and longitudinal shear reinforcement. MASON Shear Connectors / Shear studs transfer horizontal shear from slab to beam, causing the two elements to act as a unit, thereby increasing the strength and stiffness of the stud welded shear connector section without using more steel. The decking also minimises deflection, which reduces the amount of concrete required.

Composite design enables savings in steel tonnage by up to 20%, reduces building height, and saves on materials with the light beams resulting in shallower floor sections. Larger rooms can be constructed with fewer obstructions using longer beams. By facilitating faster building and reduced fabrication costs, MASON shear connectors help achieve significant time and labor costs.


MASON shear connectors comply with the EN ISO 13918 Standard and come with BCA BC1:2012 FPC Certification.

Item No.: MSS

Brand: MASON

Use: Structural Steel Construction

Type: Shear Connector

Type of fixing: Stud Welding


MASON shear connectors meet requirements of the following codes:

  • BS EN ISO 13918 Welding — Studs and ceramic ferrules for arc stud welding
  • BS 5400 Steel, concrete and composite bridges
  • BS 5950 Structural use of steelwork in building
  • AWS D1.1 Structural Welding Code –Steel

Shear connectors are typically used in composite steel construction for holding concrete slabs to steel members to resist shear forces and increase shear loading capacity in steel buildings, bridges, columns caissons, containment liners, etc. They also act as embedment anchors on miscellaneous embedded plates, frames, angles, strip plates, attachments and connections.
