Shear connectors are typically used in composite steel construction to tie the concrete to steel members and resist shear forces between the concrete slab and steel members. They are widely used oin steel building, bridges, etc.
Threaded Stud (Type PD)
The PD type studs are recommended to be used for weld to heavy gauge base materials to get full fastener strength. They have unthreaded weld base corresponds to the pitch diameter of the thread, the maximum load is identical to the load of a 4.8 screw.
Threaded Stud with Reduced Shaft (Type RD)
The RD type studs have a reduced weld base diameter. Thus they can produce a smaller weld collar diameter than other DA type studs. The smaller weld collar allows it to used on smaller clearance holes application. But the strength of the assembly is determined by the reduced weld base.
Full Threaded Stud (Type FD)
The FD type studs are threaded almost to the top of the welding tip. Thus after welding the studs are threaded up to the weld collar, they are recommended to be used in whenever full fastener length needed
Unthreaded Stud (Type UD)
The UD type studs are designed to be used in power generation industry, forging applications and locator pins, stops, etc.
Ceramic Ferrules for Shear Connector (Type UF)
Ceramic Ferrules for Shear Connectors (Through Metal Deck)
Special Ceramic Ferrules for shear connectors welding through metal deck (mostly zinc-plated deck sheets on the steel beams). As there are high amounts of degastification through zinc evaporation when weld shear connectors through zinc-plated deck sheets, the type of UFT ceramic ferrules with larger combustion chamber and larger vents can considerably improve the welding results.
