This guide is for professionals in industrial and construction fields who require highly durable fastening solutions. The Unifix Hexagon Bolts offer superior strength and a fine pitch thread for enhanced grip, ensuring secure assemblies in demanding applications. A potential caveat is the specific thread pitch, which requires compatible nuts and tools. Key features include Grade 10.9 High Tensile Strength, fine pitch threading, adherence to DIN 960 standards, and a convenient box of 25 units.

Grade 10.9 indicates a high-strength bolt classification. It signifies a minimum tensile strength of 1000 MPa and a minimum yield strength of 900 MPa.
Fine pitch threads (like the 1.5mm pitch on these M16 bolts) offer a more precise fit, greater resistance to vibration-induced loosening, and potentially higher clamping force compared to standard coarse threads.
The black finish offers some corrosion resistance, making them suitable for many outdoor applications. However, for environments with high humidity, salt spray, or constant exposure to water, additional protective measures may be necessary.
For M16 bolts, the standard across-flats (AF) dimension for the hexagon head is typically 24mm. Always confirm with your specific tool or gauge.
No, these bolts have a fine pitch thread of 1.5mm. You must use M16 nuts specifically designed with a 1.5mm fine pitch thread. Standard M16 coarse pitch nuts (2.0mm) will not mate correctly.
DIN 960 is a German Institute for Standardization (Deutsches Institut für Normung) standard that specifies dimensions and technical delivery conditions for hexagon bolts with fine pitch threads.
Store the bolts in a clean, dry place away from moisture and corrosive substances. Keeping them in their original packaging or a sealed container is recommended.
Verify you are using a compatible M16 fine pitch (1.5mm) nut or threaded hole. Check for any damage or debris in the threads of both the bolt and the mating component. Ensure you are starting the thread straight.
Ensure you are using the correct size socket or wrench for the M16 hex head. Do not overtighten or use excessive force that could round the bolt head. Consider using a 6-point socket for better grip.
The black finish provides moderate corrosion resistance. For extended exposure to moisture or corrosive agents, consider applying a suitable lubricant or protective coating. Ensure the storage environment is dry.
This indicates the applied torque exceeds the bolt's tensile strength or the material's yield point. Ensure you are using the correct torque specifications for the application and the bolt grade. Check for existing damage on the bolt.
Setup: These hexagon bolts are designed for standard hex head installation. Use a compatible socket wrench or spanner that fits the M16 head size. Ensure the bolt threads cleanly into the mating component or nut. Apply appropriate torque settings as recommended by the engineering specifications for your application to achieve optimal performance without over-stressing the bolt or the materials being joined. Always use a compatible washer where specified by the design.
Compatibility: These are M16 bolts with a 1.5mm fine pitch thread. Ensure you use M16 nuts with a 1.5mm fine pitch thread. Standard M16 coarse pitch nuts (e.g., 2.0mm pitch) will not be compatible. Also, ensure your tools are calibrated for M16 fasteners.
Care: Store bolts in a dry environment to prevent corrosion of the black finish. Avoid abrasive cleaning methods that could damage the surface. If used in highly corrosive environments, consider additional protective coatings or appropriate post-installation treatments.
