## Long description

Koelner hex nut DIN 934 M6 A2 stainless steel pack of 21 pieces is a metric hexagon nut manufactured to the DIN 934 dimensional standard. Made from A2 stainless steel, these M6 nuts provide basic corrosion resistance and strength suitable for a wide range of general fastening tasks. The pack of 21 provides a small bulk supply for repairs, maintenance or assembly work where standard M6 hex nuts are required.
Advantages
These DIN 934 M6 hex nuts are produced to standard metric dimensions for reliable fit with M6 bolts and threaded rods. The A2 stainless steel material offers resistance to rust and light corrosion in indoor and mildly corrosive environments. Supplied as a pack of 21, the set is convenient for small projects, spare parts storage or repetitive fastening tasks and reduces the need to buy single pieces repeatedly.
Suitable for
General machinery assembly and maintenance
Construction and DIY fastening tasks
Furniture assembly and repair
Light outdoor applications in non-aggressive environments
When it may not be suitable
These A2 stainless steel M6 hex nuts are intended for general-purpose fastening and offer only basic corrosion resistance. They may not be suitable for highly corrosive environments (such as marine, chemical processing, or prolonged exposure to salt water) where higher-grade stainless steels or additional protective coatings are required. For applications demanding specific mechanical properties, such as high tensile strength or certified flanges, verify compatibility with the threaded components and application requirements.
Key specifications
Thread size: M6 (metric)
Standard: DIN 934 (metric hexagon nut dimensions)
Material: A2 stainless steel (austenitic stainless steel with basic corrosion resistance)
Shape: Hexagon nut
Quantity: 21 pieces per pack
How to use
Select nuts that match the thread pitch and diameter of the M6 bolts or threaded rods you are using. Hand-start the nut onto the bolt to ensure correct engagement, then tighten with an appropriate spanner or socket to the torque recommended for M6 fasteners in your specific application. For assemblies subject to vibration, consider using a locking washer, threadlocker, or a prevailing torque nut as appropriate. Store unused nuts in a dry place to maintain their condition.
What to consider before purchase
Confirm the M6 thread pitch and compatibility with existing bolts or threaded components.
Assess whether A2 stainless steel corrosion resistance is sufficient for the intended environment.
Determine if a pack of 21 pieces matches project needs or if a different quantity is required.
Usage recommendations
Use these Koelner DIN 934 M6 A2 nuts with matching M6 bolts and apply recommended torque values for metric fasteners. For environments with higher corrosion risk or specific strength requirements, choose a higher-grade material or consult technical guidance. Keep spare nuts from the pack readily available for maintenance tasks.
