2. Expansion Screws These screws are designed for concrete or masonry walls. When installed, they expand and grip the surrounding material as the screw is driven into it, creating a robust anchor point.

A double end stud, as its name implies, is a type of fastener that features two threaded ends with a unthreaded shank in between. This unique configuration allows it to serve as a versatile connector in a range of applications. Historically, the design of the double end stud emerged from the need for robust fastening solutions that could withstand significant stress and load. Its origins can be traced back to the industrial revolution when the demand for durable and reliable construction materials surged as industries expanded.

An M6% resin anchor is a type of fastener designed to be embedded into a substrate, primarily concrete, using a high-strength resin adhesive. The M6 designation refers to the metric thread size; this means that the anchor has a nominal diameter of 6 millimeters. The % indicates that the resin is formulated to perform effectively under various conditions, enabling a secure bond regardless of the environment. This type of anchor is ideal for applications requiring substantial load-bearing capacity while maintaining a non-corrosive and durable bond.
