Socket screws and bolts form finer fastenings

Challenge Europe stock holding also encompasses closely related button head or dome head socket screws which feature a lower profile with smooth finish.

Related to socket screws and bolts is the socket head shoulder screw with its own plain shank which has a precision ground surface for exact location of components. Sometimes described as a ‘dowel with a thread’ the socket head shoulder screw is often used in tooling applications as it has a lower clearance requirement enabling positive location with a precise fit. The ground surface can often double as a bearing surface in low stress applications.
