external wall insulation screws

Tek screws are designed with a unique combination of materials and manufacturing processes that ensure their superior performance. They are typically made from high-grade steel, which provides the necessary strength and resilience to withstand various environmental conditions and demanding applications. The screws are then subjected to a heat treatment process that enhances their hardness and resistance to corrosion, further extending their lifespan.

Indented foundation bolts, also known as anchor bolts, are designed with a unique feature - an indentation or groove on their surface. This indentation serves a dual purpose. Firstly, it increases the surface area in contact with the concrete, thereby enhancing the bond strength between the bolt and the foundation. Secondly, during the tightening process, the indentation acts as a stress concentrator, causing the concrete around it to fracture, creating a mechanical interlock. This mechanism significantly improves the load-bearing capacity and resistance to shear forces.
