The force required to initiate the first relative movement between the bolt and the mating part.
The standard requires system tests at room temperature and at these elevated limits to ensure the adhesive bond does not degrade or liquefy under heat. For these tests, specialized ovens meeting DIN 50011-12 accuracy classes are used. 3. Critical Testing and Verification
While search results often reference "DIN 26727" as a shorthand, the official designation is , a critical standard for fasteners with micro-encapsulated (MK) adhesive coatings . This standard ensures that screws and bolts remain securely locked under high-vibration or high-temperature conditions.
DIN 267 bolt | DIN 267-27 fasteners specification, sizes and Grades
A suitability test is performed on a reference bolt to qualify the adhesive itself, while a system test evaluates the adhesive's performance on the specific production fastener (including its surface finish). 4. DIN 267-27 vs. Hot-Dip Galvanizing (HDG)
