This M20 x 2.5mm hex tap bolt is manufactured from Class 10.9 high-strength steel with a zinc plated finish for reliable corrosion resistance in indoor and sheltered outdoor applications. The partial thread design leaves an unthreaded shank section below the hex head, reducing stress concentration at the bolt-to-joint interface and providing superior shear strength compared to fully threaded alternatives. Class 10.9 steel delivers approximately 1,040 MPa tensile strength, making these fasteners suitable for heavy-duty structural connections, machinery assembly, and high-load applications where standard Class 8.8 bolts are insufficient. The zinc plating adds a protective barrier against moisture and mild environmental exposure while maintaining RoHS compliance.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
