Hex head timber screws, also known as timber hex screws, are specialized fasteners designed for use in wood construction and carpentry applications. These screws feature a hexagonal head, providing enhanced driving torque and resistance to stripping, making them well-suited for demanding wood fastening tasks. Understanding the applications, benefits, and selection considerations of hex head timber screws is essential for ensuring their effective use in wood-based projects.

DIN 125A2 is a standard established by the Deutsches Institut für Normung e.V. (German Institute for Standardization) that outlines the specifications for flat washers. These washers are typically used in conjunction with bolts and nuts to distribute loads, reduce the likelihood of deformation, and prevent damage to the surface material upon which they are fastened. The A in the designation signifies that the washers are of type A, which typically refers to an extensive range of sizes, providing flexibility in fastening applications.
