Flanged Serrated Hex Bolts

Flanged serrated hexagon bolts provide a strong, vibration resistant fixing solution for structural, mechanical and general engineering applications where secure locking and load distribution are required. Designed with an integrated serrated flange beneath the hex head, these bolts act as a built in washer while the serrations bite into the mating surface to resist loosening under vibration. This makes them ideal for applications where additional locking devices are not required and where joint integrity is critical. Commonly used in steelwork, machinery, automotive assemblies, frames, brackets and fabrication work, flanged serrated hex bolts deliver reliable clamping while simplifying installation. Manufactured to DIN 6921 standards, they are suitable for use in both structural and high vibration environments.

Supplied in commonly used diameters and lengths, flanged serrated hexagon bolts are available in strength grades and corrosion resistant finishes including zinc plated grade 8.8 and stainless steel A2 to suit internal, external and demanding applications. Selected for dependable locking performance, strong fixing strength and suitability for professional trade and engineering use, they provide an effective solution for secure bolted connections without the need for separate washers or locking components.
