M16 Hexagon Nut DIN 6331 With Collar Forged Strength Class 10, SW24mm - AMF

Take advantage of the combination of forged construction, a flanged collar and strength class 10 for consistently reliable bolted connections; these characteristics reduce loosening and improve load distribution under heavy duty. Order the Hexagon nut DIN 6331 M16 directly via Metav Werkzeuge or ask our consultants if needed.

Hexagon nut DIN 6331 M16 — AMF forged, strength class 10

A Hexagon nut DIN 6331 M16 designed for secure, high-strength bolted assemblies in industrial and structural applications.

• Flanged design for secure seating
• Forged and tempered for high strength
• Strength class 10 for heavy-duty joints
• Spanner size SW 24 mm for M16 fastenings

Consistent clamping reliability for structural joints

The forged collar nut delivers a predictable contact surface and improved force distribution compared with plain hex nuts. Thanks to the flanged geometry, bearing stresses on the mating surface are minimised, which reduces the risk of surface damage and improves joint integrity. Conformity with DIN 6331 ensures compatibility with standard metric fastenings and simplifies component selection for assembly lines and maintenance routines.

Built for performance: material treatment and resistance to fatigue

Heat treatment indicated by tempering (quenched and tempered) increases toughness and load-bearing capability while maintaining ductility. The forged manufacturing process produces a dense grain structure that enhances mechanical strength; combined with strength class 10, this gives a reliable margin for high-torque applications. For procurement specialists and design engineers, these factors mean fewer failures, lower rework rates and longer maintenance intervals.

Efficient assembly and tool compatibility

Designed for standard M16 threads and a spanner size of SW 24 mm, the fastener integrates seamlessly into existing tool sets and assembly procedures. The clear spanner dimension reduces fitting errors and speeds installation, while the flanged seat lessens the need for separate washers in many applications. These practical advantages translate directly into improved throughput on production lines and easier field repairs.

Application areas and quality assurance

Suitable for heavy machinery, structural steelwork and bolted connections where high clamping force and durability are required. The combination of DIN 6331 specification, forged manufacture and tempering makes this fastener well suited to repetitive load cycles and industrial environments. For operators seeking supply reliability, Metav’s distribution acts as a quality filter for the European market, ensuring consistent product provenance and traceability.
