Product Details
Our DIN 6921 Hex Flange Bolts are distinguished by their fully threaded body and a protective White Zinc Plated finish. The full-length threading provides maximum engagement with nuts or tapped holes, making them exceptionally versatile for clamping materials of various thicknesses or for applications where the bolt’s position needs to be adjustable. The White Zinc Plating (also known as clear zinc or blue zinc) is an electro-galvanized finish that deposits a layer of zinc onto the carbon steel substrate. This coating acts as a sacrificial barrier, protecting the steel from oxidation and providing a bright, clean, and aesthetically pleasing appearance. Available in a range of carbon steel property classes such as 4.8, 8.8, and 10.9, these bolts deliver the mechanical strength needed for reliable joints. The integral flange ensures that clamping pressure is spread over a wider area, preventing damage to the mating surface and enhancing the fastener’s resistance to loosening.

Product Features
These Fully Threaded White Zinc Plated Flange Bolts offer a unique set of features designed for efficiency and reliability. Their Maximum Thread Engagement is a key advantage; the fully threaded shank allows for secure fastening in deep tapped holes or with nuts positioned anywhere along the bolt, providing unparalleled clamping adjustability. The Clean & Protective Finish of the White Zinc Plating offers good corrosion resistance for indoor environments while delivering a bright, professional aesthetic. The Streamlined One-Piece Construction, featuring an integrated flange, acts as a built-in washer to distribute load effectively, simplify inventory, and speed up assembly. Forged from High-Quality Carbon Steel, these bolts are available in multiple grades to provide the necessary tensile strength for secure, long-lasting connections. Finally, strict adherence to the DIN 6921 Standard guarantees dimensional consistency, ensuring a perfect fit and reliable performance in any compatible assembly.
Product Applications
The versatility and clean finish of our Fully Threaded White Zinc Plated DIN 6921 Bolts make them ideal for a broad spectrum of applications. In General Manufacturing and Machinery Assembly, they are used to secure machine guards, mounting plates, and components where full thread adjustability is beneficial. Within the Electronics Industry, they are perfect for assembling server racks, electrical enclosures, and control panels, where the clean finish and reliable connection are highly valued. In Appliance Manufacturing, these bolts are used for internal structural connections and mounting brackets. They are also a staple in Prototyping, DIY Projects, and Repair Shops due to their adaptability in clamping different material thicknesses. Furthermore, their use in Furniture Construction and Retail Fixturing is common, as the integrated flange and clean appearance provide a secure and finished look without extra hardware.
