Expanding plastic screw anchors, often referred to as wall anchors, are designed to secure objects by expanding as a screw is driven into them. Typically made from durable plastic, these anchors are inserted into a pre-drilled hole in the wall. When a screw is inserted into the anchor, it pulls the anchor wings outward, gripping the surrounding material tightly. This expansion creates a hold strong enough to support various weights, making them ideal for a wide range of applications.

A 4PCS fix anchor is a type of anchoring system designed to provide strong, secure holds for various construction materials, particularly in masonry and concrete settings. The term 4PCS refers to the design consisting of four components, which typically include an anchor bolt, a washer, a nut, and a sleeve or expansion component. This multi-part construction allows the anchor to offer enhanced grip and stability, distributing weight and resisting pull-out forces more effectively than simpler designs.

The heavy hex head bolt consists of a threaded shank and a large hexagonal head, which provides a larger surface area for better grip and torque transmission. The head design also prevents the bolt from turning during installation, ensuring a secure fit. The thread pitch and diameter of the bolt are crucial factors that determine its mechanical properties, such as tensile strength and shear strength. Generally, heavier bolts have greater strength due to their increased material volume.
