Hexagon nut DIN 6331 M14 – SW 21 mm, strength class 10 (AMF)

Hexagon nut DIN 6331 M14 engineered as a high‑strength metric fastening solution for industrial assemblies and machine construction

• DIN 6331 compliance for interchangeability
• Strength class 10 for high clamping loads
• SW 21 hexagon for standard spanners
• Compact overall height of 21 mm for tight spaces

Consistent clamping force for heavy‑duty joints

The M14 thread in combination with strength class 10 provides a clear advantage where elevated clamping forces are required. The reinforced material grade behind this classification allows the fastener to transmit higher preload without premature deformation, which directly improves joint reliability in production environments. For engineers and assemblers this means fewer re‑work cycles and a lower risk of joint loosening under dynamic loads, translating into measurable process stability.

Standardised form for rapid assembly and serviceability

Compliance with DIN 6331 and the standard SW 21 across the hexagon faces ensures compatibility with common tools and automated tightening equipment. The specified overall height 21 mm and corner‑to‑corner dimension 23.4 mm (Eckenmaß) support predictable wrench engagement and torque application. The pressed and milled manufacturing method yields defined contact faces and accurate geometry, which improves torque transfer and reduces the chance of rounding during tightening — a practical benefit for maintenance intervals and in-line assembly.

Reduced assembly time and dependable inventory handling

Using a standardised hexagon nut like this AMF fastener simplifies procurement and stock management: metric thread designation M14, clear article identification and single‑unit packaging keep logistics straightforward. The compact design supports installation in confined assemblies without compromising load capacity. For operations managers this reduces inventory complexity and supports just‑in‑time workflows while maintaining the required mechanical performance.
