Hex screws, or hexagon socket screws, are fasteners characterized by their hexagonal shape, which allows for a firm grip when using a hex wrench or socket. Typically made from durable materials such as stainless steel or hardened carbon steel, they come in different lengths and diameters to suit various projects. Their unique design offers a significant advantage over traditional screws, as they can bear higher torque, making them less likely to strip during installation.

Shear studs come in various sizes and configurations, but certain standard sizes are widely accepted in the industry. The most common sizes range from 10 mm to 22 mm in diameter, with lengths varying typically from 50 mm to 150 mm. The choice of size depends on several factors, including the width of the flange of the steel beam, the depth of the concrete slab, and the anticipated loads.
