Anchor bolts are a type of steel anchors that are used to connect structural and non-structural elements to the concrete. The attachment is made through assembling of different components such as anchor bolts, steel plates, and stiffeners. Shear and tension forces are types of load that are transferred by anchor bolts. A plastic anchor sleeve is the go-to sleeve if one wants ease of use and affordable installation of anchor bolts into concrete.

A 4140 steel means it is a low alloy steel consisting of manganese, chromium, and molybdenum. It’s made by combining iron, carbon, and the three elements in an oxygen furnace. The latter are mainly for resisting corrosion. Once these are molten, they are allowed to cool then annealed, a process that involves heating steel at a certain temperature before allowing it to slowly cool down at a controlled rate. This process improves machinability and electrical conductivity.

A 4140 steel has a tensile strength of approximately 95,000 psi, the ultimate tensile strength. It’s known for its ductility, toughness, and hardenability.
