Din 5464 Standard Pdf ((install))

Exposition: DIN 5464 — Overview and Key Points

DIN 5464 vs. ISO 10511

• ISO 10511 is for prevailing torque hexagon nuts (nylon insert or distorted thread) – fine pitch.
• DIN 5464 is for non-prevailing torque (free-spinning) nuts.
• Note: Many older European drawings use DIN 5464, but the current trend is shifting toward ISO standards. However, DIN 5464 remains active because fine-pitch flanged nuts are not fully covered by ISO 4161 (which focuses on coarse threads).

Mechanical Properties

The standard references material requirements. For a property class 10 nut:

• Proof Load Stress: 1,040 MPa (minimum)
• Hardness: 295 to 353 HV
• Surface Discontinuities: Limited per ISO 6157-3.

Key Characteristics of DIN 5464:

• Shape: Hexagon with an integrated flange (serrated or non-serrated bearing surface).
• Thread Type: Metric fine pitch thread.
• Strength Classes: Typically 8, 10, and 12 (high-strength applications).
• Material: Usually steel, with options for zinc plating or other corrosion-resistant coatings.
