A hex washer head bolt is essentially a threaded rod with a hexagonal head, providing a larger surface area than a standard hex bolt. The integrated washer portion of the bolt serves two primary functions. Firstly, it distributes the clamping force over a wider area, preventing damage to the material being fastened and reducing the risk of loosening due to uneven pressure. Secondly, it increases the friction between the bolt and the surface, enhancing the holding power and ensuring a secure connection.

A shear stud bolt is essentially a steel rod with a head on one end and a threaded end for anchorage. They are typically used in composite beams and floors where they act as connectors between the steel beam and the concrete slab. The term shear refers to the force that tends to slide one part of a structure over another, perpendicular to the direction of the force. In such scenarios, shear studs serve as a critical line of defense against these potentially damaging forces.

M16 concrete anchors are designed to secure various fixtures and structures to concrete surfaces. The M16 designation refers to the diameter of the anchor, which is approximately 16 millimeters, making it suitable for a wide range of applications that require a robust yet precise fastening solution. These anchors typically consist of high-quality materials such as stainless steel or hardened metals, ensuring durability and resistance to corrosion, even in harsh environments.
