## Long description

Hex Head Bolt Koelner DIN 933 6x25 mm A2 stainless steel, pack 6 is a fully threaded hexagon-head bolt manufactured to DIN 933 standard. Made from A2 stainless steel, this bolt offers corrosion resistance suitable for general fastening applications in metalwork, construction and machinery assembly. Supplied as a pack of six, the bolt has a nominal diameter of 6 mm and a length of 25 mm measured from under the head to the end of the thread.
Advantages
The A2 stainless steel construction provides good resistance to rust and staining in typical indoor and mildly humid environments. Full threading along the shank allows for adjustable clamping length and firm engagement with nuts or tapped holes. The hex head design enables secure torque application with standard spanners or sockets, ensuring reliable tightening and ease of assembly.
Suitable for
 General metalwork fastening and joining
 Construction and light structural assemblies

 Applications requiring adjustable clamping using fully threaded bolts
 Indoor and mildly humid environments
Key specifications
 Material: A2 stainless steel (austenitic stainless steel)
 Standard: DIN 933 (hex head, fully threaded)
 Diameter: 6 mm
 Length: 25 mm (measured from under head to end of thread)
 Thread type: full thread

How to use
Select an appropriate nut or a threaded hole with compatible metric M6 internal thread. Insert the bolt through the assembled parts so that the head rests against the surface and engage the nut on the protruding thread or screw into the tapped hole. Use an appropriately sized spanner or socket to tighten the hex head to the required torque for the application, taking care not to exceed recommended torque values for M6 bolts in A2 stainless steel to avoid thread or material damage.
Usage recommendations
For improved corrosion performance in outdoor or highly corrosive environments, consider using higher-grade stainless steel or applying suitable coatings. When fastening structural or load-bearing joints, verify torque and material compatibility and, where necessary, use lock washers or thread-locking compounds to prevent loosening under vibration.
