Elevate your industrial assembly and construction projects with our high-performance Hexagon Head Bolts, manufactured in strict accordance with the DIN 931 standard. Crafted from premium Stainless Steel A4 (also known as AISI 316), these fasteners are engineered to provide superior mechanical strength and exceptional resistance against corrosion. The image displays a robust bolt featuring a precise hexagonal head for optimal torque application and a partially threaded shank, ideal for applications requiring shear strength and precise alignment.
Made from Stainless Steel A4, offering excellent durability and resistance to rust, chemicals, and harsh environmental conditions, including marine environments.
Adheres to international DIN 931 specifications, ensuring consistent dimensions, thread pitch, and head geometry for reliable compatibility with standard nuts and tools.
The hexagon head allows for easy installation using standard wrenches or sockets, while the unthreaded shaft portion provides enhanced stability and load-bearing capacity in structural connections.
Featuring clean, uniform threading and a smooth finish, these bolts ensure secure fastening and reduce the risk of stripping during installation.
Invest in reliability and precision with our DIN 931 Stainless Steel A4 Hexagon Bolts, the dependable choice for secure and enduring mechanical connections.

DIN 931 is the German industrial standard for hexagon head bolts with a shank (partially threaded), which has been officially replaced by the international standard ISO 4014. Dimensions and specifications between both standards are virtually identical for most industrial applications.
Stainless Steel A4 (AISI 316) contains molybdenum, giving it significantly higher resistance to corrosion, saltwater, acids, and aggressive chemicals compared to standard A2 (AISI 304) stainless steel. It is ideal for marine and harsh industrial environments.
By definition, DIN 931 bolts feature an unthreaded shaft (shank). However, for short length dimensions, the thread may extend closer up to the head due to manufacturing design limitations.
Our DIN 931 Stainless Steel A4 Hexagon Bolts are available in thread dimensions ranging from M 5 x 30 up to M 36 x 250, catering to various mechanical and heavy-duty structural applications.
External hexagon bolts can be easily installed or removed using standard metric open-ended wrenches, ring spanners, socket sets, or torque wrenches suitable for external hexagonal bolt heads.
