10.9 Metric fasteners, resembling inch fasteners in style and use, require careful identification to avoid mix-ups. Theyre measured in millimeters, with distinctive head markings. Bare metal fasteners have no corrosion resistant qualities and are a good choice for indoor and industrial applications. The 10.9 class, similar to SAE Grade 8, indicates alloy steel, quenched, and tempered steel fasteners with notable tensile strength, used across contractors, designers, OEMs, and maintenance staff for critical joints and high stress applications.
- Made from alloy steel, quenched, and tempered These bolts undergo a heat treatment process consisting of quenching (rapid cooling from a high temperature) and tempering (reheating to a lower temperature and then cooling) to achieve their high strength and toughness Use with Class 109 nuts to develop full strength of the cap screw
- Available in Coarse, Fine threads with fully threaded or partially threaded lengths DIN 931 = Partial Thread, DIN 933 = Full Thread
- Made from alloy steel 109 bolts are suitable for applications requiring high tensile strength and load-bearing capacity, such as in automotive, machinery, and structural engineering projects
