You can find the latest DIN 267-27:2024-07 version here.

The is a crucial regulatory document that outlines the technical delivery conditions and functional properties for adhesive-coated steel screws, bolts, and studs . Specifically focusing on microencapsulated (MK) adhesive pre-coatings, the standard ensures that threaded fasteners maintain their clamping force under intense operational stress.

Refined technical delivery parameters and expanded test bolt protocols. Modified globally into national versions like GOST R. Current & Active

The standard dictates acceptable limits for the breakaway torque ( MLBcap M cap L cap B ) and the subsequent unscrewing torque ( Moutcap M o u t

The sealant fills the gaps between the threads, protecting against leakage of fluids and gases.

. While DIN 267-27 focuses on adhesives, many heavy-duty fasteners must meet both locking requirements corrosion resistance standards like (Hot-Dip Spun Galvanized Coatings). A "hot" setup for harsh environments often includes: Corrosion Barrier

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.

These tests are critical for ensuring that the locking function is neither too weak (failing to secure the joint) nor so strong that it inhibits assembly. You can find the latest DIN 267-27:2024-07 version here

: When the bolt is screwed in, the capsules break and release an adhesive that hardens to lock the thread.

The keyword refers to the German technical standard DIN 267-27 , which governs the delivery conditions for steel fasteners (screws, bolts, and studs) that feature a pre-applied adhesive coating .

Depending on the chosen chemical compound class, typical adhesive pre-coatings are engineered to withstand temperatures ranging from (and occasionally up to +200∘Cpositive 200 raised to the composed with power C

Adhesive-coated fasteners, often referred to as "hot" or "pre-applied" locking fasteners, offer significant advantages over traditional mechanical locking methods: Refined technical delivery parameters and expanded test bolt

Thermal degradation of polymers, resulting in loss of clamping protection.

To satisfy DIN 267-27, adhesive-coated fasteners must pass a series of rigorous testing protocols managed via strict reference parameters: Breakaway and Unscrewing Torques

The liquid chemical fills the interstitial thread gaps and undergoes an anaerobic curing cycle. This turns the substance into a tough, high-molecular-weight plastic framework that fuses the internal and external threads together. Coating Zone Geometry
