is the standard for high-performance adhesive-coated fasteners, ensuring reliability in demanding industrial applications involving vibration and heat. By specifying the material, testing, and performance requirements, this standard ensures that pre-applied adhesive coatings deliver consistent, high-strength locking and sealing properties from
The updated current release can be found directly on the European Standards Repository (DIN 267-27) .

: The adhesive remains dormant within microscopic, pressure-sensitive capsules during transport and storage. When the bolt is driven into a mating thread or nut, the resulting mechanical shear forces rupture these microcapsules. This releases a liquid chemical monomer that rapidly cures into a high-strength polymer matrix, permanently locking the joint.

The micro-encapsulated adhesive remains dormant until assembly. When the bolt is screwed into a nut or tapped hole, the capsules burst, releasing the adhesive and initiating the curing process. 2. Performance at High Temperatures ("Hot" Applications)

The standard enforces these constraints to prevent over-tightening during installation while establishing minimum breakaway thresholds so that vibrations cannot back the assembly out under severe operational strain. ⚠️ Critical Engineering Best Practices ) : The resistance encountered while driving the
The technical specification includes strict testing guidelines for high-temperature environments. The adhesive compound must not degrade, soften excessively, or fail prematurely when exposed to thermal stress.
