expansion bolts for hollow structural steel sections

Shear studs are typically welded to the steel section of a composite beam before concrete is poured. Their primary function is to transmit shear forces between the steel and the concrete, preventing the two components from sliding apart under load. This connection enhances the load-carrying capacity of the beam and allows for a more efficient use of materials, ultimately leading to lighter and more cost-effective structures.

One of the primary functions of drilling wing tip screws is to maintain the structural integrity of the wing during flight. The constant changes in altitude, speed, and temperature can cause the wing components to expand and contract, which could lead to fatigue and eventual failure if not properly secured. By using drilling wing tip screws, aircraft manufacturers can ensure that the wing remains rigid and stable, thereby enhancing the overall safety of the aircraft.
