Headed shear studs can be directly welded, or through-deck welded, to the steel beam flange after the decking has been installed. 

The Hilti X-HVB shear connector is a mechanically attached shear transfer device for use in composite beam construction as a substitute for through-deck shear studs.

Hilti Software Tutorial

Transmit the horizontal shear force between the concrete and beam connection and are commonly used in the design and construction of composite beams. 

• Unlike welded studs, HVBs can be installed to galvanised beams or in areas where a high fire risk exists.

• Fast and simple installation.

• No electrical power source required. 

• Shear studs manufactured in accordance with BS EN ISO 13918:2008

• Yield Strength – 350N/mm² (minimum)

• Tensile Strength – 450N/mm² (minimum)

• Elongation – 15% (minimum) 

• Yield Strength – 295-350N/mm²

• Zinc coating – ≥ 3 μm 

 The above are the most typical options for use with SMD products. Other sizes are available.
