Shear studs (Type SD1) are manufactured from low carbon steel with a minimum yield strength of 350 N/mm² and a minimum ultimate tensile strength of 450 N/mm² in accordance with BS EN ISO 13918.

Type SD shear connectors as defined in BS EN ISO 13918, are available in 16mm, 19mm, 22mm and 25mm diameter with varying lengths to achieve from 70mm to 170mm length after weld (LAW).

Typical situations where welded shear studs are used include:

• Thru-deck Stud Welding (on site) for Composite Beams
• Stud Welding at Works for Composite Beams
• Plunge Columns
• Steel Piling
• Bridge Construction/Refurbishment
• Refractory Lining and Insulation Connectors
• Wear Resistant Studs The most common use of welded shear studs (Type SD1) is in the construction of Composite Beams, refer Section 6.
