The "hot" keyword in your search likely refers to the hot-application or heat-curing properties of these coatings, or perhaps the hot-dip galvanized surface finishes often used on the bolts themselves before the adhesive is applied. 🛠️ DIN 267-27 Standard Overview
This standard specifies requirements for bolts, screws, and studs (sizes M3 to M39) that are coated with a micro-encapsulated adhesive to prevent loosening.
Function: When the bolt is screwed in, the capsules break and release an adhesive that hardens to lock the thread.
Temperature Range: Typically effective from -60°C to +150°C, though "hot" applications may require specialized high-temperature grades.
Testing: Includes torque measurements (breakaway torque) and prevailing torque after the adhesive has cured. 📄 Available PDF Resources

Pac2 Standard (DIN 267-27 Equivalent): This Technical Data Sheet explains the dimensions and test specifications for micro-encapsulated adhesive threadlockers (like Dri-Loc®) and explicitly mentions its conformity to DIN 267 part 27. din 26727 pdf hot
Woodward Manual 26727: If you were looking for a product manual rather than a DIN fastener standard, this Product Manual covers the VariStroke-I Electro-Hydraulic Actuator, which is often searched for using the number "26727". 🔍 Key Technical Specs Feature Requirement (DIN 267-27) Thread Sizes Property Classes All classes up to 12.9 Coating Length Typically 1.5d ± 2P (d=diameter, P=pitch) Curing Time Usually 24 hours for full strength at room temp
Could you clarify if you are looking for the fastener adhesive standard (DIN 267-27) or the Woodward actuator manual (Manual 26727)? I can provide more specific torque tables or wiring diagrams depending on which one you need.
The standard DIN 267-27 (often written without the hyphen as DIN 26727) focuses on fasteners with pre-applied adhesive coatings. It does not specifically cover "hot" processes like hot-dip galvanizing, though it is often used for fasteners that may have been previously hot-treated. 📄 Quick Overview: DIN 267-27
Purpose: Technical specifications for steel screws, bolts, and studs with micro-encapsulated adhesive coatings.
Function: Ensures fasteners are "self-locking" to prevent loosening under vibration.
Key Metrics: Defines adhesive performance, required torque for breaking the bond, and temperature resistance. Latest Version: A new edition was published in July 2024. 🔍 Clarifying "Hot" vs. DIN 267-27 The "hot" keyword in your search likely refers
If you are looking for information on "Hot-Dip Galvanizing" (which adds a thick zinc layer to prevent rust), you are likely looking for DIN EN ISO 1461 or DIN EN ISO 10684 (specifically for fasteners). DIN 267-27 (Adhesive) ISO 10684 (Hot-Dip Galvanizing) Primary Goal Vibration resistance (Locking) Corrosion protection (Rust-proof) Application Chemical adhesive coating Molten zinc bath at ~450°C Typical Thickness Micro-thin layer 45 to 85+ microns Common Use Engine bolts, automotive Outdoor structures, heavy bolts 💡 Key Technical Details
Interchangeability: DIN 267-27 is frequently replaced or used alongside ISO 10964 for testing adhesive bonds.
Temperature Ranges: Adhesive coatings under this standard are typically rated for service temperatures between -60°C and +150°C (higher for specialized "hot" engine applications).
Coating Thickness: For hot-dip galvanizing, thickness is the "single most important measurement" for lifespan. You can find detailed measurement guides on the American Galvanizers Association website. 🛠️ Next Steps
To help you get the exact data or PDF guide you need, could you clarify:
This is the "hot" part literally. For elevated temperature tests, the standard requires the bolt to be heated to the specified temperature (e.g., 300°C) for a minimum of 48 hours while the clamp load is measured. Section 6: Test Temperature This is the "hot"
Before we dive into the download aspects, let’s clarify the standard itself. DIN 26727 is a German Institute for Standardization (Deutsches Institut für Normung) document that specifically addresses Mechanical properties of fasteners – Parts for high-strength structural bolting with preload.
However, a critical note for searchers: Many people confuse DIN 26727 with the broader ISO or EN standards. Historically, DIN 267 was a series covering fastener properties. DIN 267-27 (often written as DIN 26727) specifically dealt with stress relaxation testing of fasteners.
In the fastener industry, the most common variation of this standard required for outdoor or heavy industrial use is the Hot-Dip Galvanized version.
If you are sourcing these parts, you are likely looking for DIN 26727 Nuts, Hot-Dip Galvanized.
