DIN 933 Bolt

M6–M20+ · 4.8 / 8.8 / 10.9 / 12.9

DIN 933 / ISO 4017
DIN 933 fully threaded hex head bolts (Hex Bolt): metric thread, 4.8, 8.8, 10.9 and 12.9 strength classes, zinc-plated and other surface finishes.

DIN 933 bolts are fully threaded, hex head fasteners. They are widely used in machine building, construction, steel structures, equipment assembly and various mechanical connections. They are also known as Hex Bolt, Hexagon Head Bolt and Full Thread Bolt.

DIN 933 bolts have a metric thread and are used together with a nut to create a strong, reliable connection. Bolt size is defined by diameter and length: M6, M8, M10, M12, M16, M20 and larger sizes are available in various lengths.

Key characteristics

  • Hex head, fully threaded construction
  • Metric thread system
  • Various diameter and length options
  • 4.8, 8.8, 10.9 and 12.9 strength classes
  • Zinc-plated (white, yellow), black oxide and other surface finishes
  • Compliance with DIN 933 / ISO 4017

Strength classes

  • 4.8: standard and relatively lightly loaded connections
  • 8.8: general industrial, construction and mechanical connections
  • 10.9: structures under higher loads
  • 12.9: mechanical connections requiring high strength

Applications

DIN 933 hex bolts are used in steel structures, machine building, industrial equipment, construction and assembly work, engineering systems, automotive and technical installations, and repair and service work. They are especially used to mechanically join profiles, plate, channels, I-beams and other structural steel elements.
