Chemical anchors consist of a resin or adhesive that, when mixed with a hardening agent, polymerizes to form a strong bond with the base material. These anchors are typically used in conjunction with metal rods or bolts that are inserted into drilled holes. The chemical reaction that occurs once the resin is mixed makes the bond resistant to shear and tensile stress, significantly outperforming traditional anchoring solutions in many scenarios.

A double end threaded stud is essentially a cylindrical rod with threaded ends, allowing for secure attachment to nuts or other threaded components. The unique feature of the double end threaded stud with wrench flats is the addition of flats on the shank, which provide a surface for wrenches to grip during installation and removal. This design is particularly valuable in tight spaces where traditional fastening methods may be challenging. The flats enable users to apply higher torque without damaging the threads or slippage, making it easier to achieve the correct tightness.
