Diall M12 Hex Bolt & Nut - Carbon Steel - Grade 5.8 - L120mm - Pack Of 10

These bolts are Grade 5.8, indicating their strength and load-bearing capacity.

These bolts are suitable for use with a variety of materials, including wood, metal, and plastic, provided the material has appropriate pre-drilled holes for the bolt diameter and has sufficient thickness to support the bolt.

The wrench size will be determined by the nut's size and shape. Check the nut's dimensions for the correct wrench or socket size. As a general guide, M12 bolts often require a 19mm wrench.

Yes, the zinc plating provides corrosion resistance, making them suitable for outdoor applications. However, regularly inspect them for wear and tear.

While these bolts are robust, they are not designed for extremely high-stress, critical applications. Assess the load requirements of your project and ensure the bolts' grade is appropriate.

Ensure the nut is properly tightened. For applications with vibration, consider using a locking nut or applying thread locker.

The bolts are 120mm in length.

Verify the hole size and the bolt diameter (M12). Enlarge the hole if necessary, but ensure it does not compromise the structural integrity.

Ensure the threads on both the bolt and the nut are clean and undamaged. Apply a lubricant if necessary, and use the correct size wrench or socket.

Re-tighten the nut to the appropriate torque. Consider using a locking nut or thread locker for applications where vibration is present.

Clean the bolt and apply a rust inhibitor. Consider replacing the bolt if the corrosion is extensive and compromises the strength of the bolt.
