[Fastener Thread] ---> [Microcapsules Layer (Dry to Touch)] | (Assembly Torquing) | v [Capsules Rupture & Mix] ---> [Chemical Curing / Locking]
As temperature scales upward, the cross-linked polymers within microencapsulated adhesives temporarily soften. DIN 267-27 outlines exact retention ratios for torque capacity at hot thresholds (typically scaling between depending on the specific adhesive chemistry class specified). To secure compliance, fasteners undergo hot system tests: din 26727 pdf hot
Fasteners conforming to this standard are pre-coated with microcapsules containing an adhesive base and a hardening agent. When the bolt is threaded into a mating component, these capsules rupture, initiating a chemical curing process that fills the thread clearances.

The DIN 26727 standard is crucial for ensuring the safety and reliability of steel structures, particularly in construction projects where bolted connections play a critical role. By following the guidelines outlined in the standard, engineers and designers can:
