The standard often referred to by the search term DIN 267-27 (frequently searched as "DIN 26727") covers technical specifications for fasteners with pre-adhesive coatings, specifically steel screws, bolts, and studs. The latest version was released in July 2024 by DIN Media. 🛠️ Technical Focus
DIN 267-27 defines the requirements for micro-encapsulated adhesive coatings applied to threaded fasteners. These coatings are designed to: Prevent loosening due to vibration or transverse loads. Seal threads against liquid or gas leaks.
Ensure consistent torque during assembly, with specific breakaway and prevailing torque values. Key Specifications Material Scope Steel screws, bolts, and studs. Coating Type Micro-encapsulated (MK) adhesives (e.g., Dri-Loc). Testing Temperature
Performance is tested at room temperature, 100 °C, and 150 °C. Property Classes Commonly applies to classes 8.8, 10.9, and 12.9. 📂 Recent Updates (2024)
The July 2024 revision introduced critical corrections to torque values found in earlier 2023 drafts:
Tightening Torque (M27): Corrected from 100 Nm to 1,000 Nm for high-strength classes (8.8, 10.9, 12.9).
Breakaway Torque (M8): Adjusted from 9.5 Nm to 9.9 Nm for lower classes (5.6, 5.8). Breakaway Torque (M22): Adjusted from 261 Nm to 216 Nm. 🛒 Where to Find the PDF
