FAQs

What does Grade 4.8 mean?

Grade 4.8 refers to the tensile strength and yield strength of the steel, indicating it is suitable for general purpose or light-duty mechanical applications.

Are these allthreads suitable for outdoor use?

They feature a bright zinc plating which provides some protection, but they are primarily recommended for indoor or sheltered environments.

Can I cut these to a shorter length?

Yes, you can cut these to the desired length using a hacksaw or bolt cutter, though you should clean up the burrs on the threads afterward.

Do these come with nuts included?

No, the Unifix allthreads are provided as the studs only. M6 nuts must be purchased separately.

What is the diameter of the thread?

These are M6 size, which corresponds to a 6mm nominal thread diameter.

Troubleshooting

Nut does not thread smoothly onto the stud.

Check the thread pitch and diameter for debris. Ensure the stud is not cross-threaded during the initial rotation.

Surface discoloration or light oxidation.

Clean the surface with a fine wire brush or light solvent and re-apply a protective lubricant or anti-corrosion spray.

Pros and Cons

Pros

  • High manufacturing precision adhering to DIN standards
  • Enhanced corrosion resistance from the BZP finish
  • Easy to cut or modify for custom assembly lengths
  • Consistent thread pitch for smooth nut installation

Cons

  • Limited to light-to-medium load applications
  • Not suitable for high-stress or high-tensile structural environments
  • Limited outdoor longevity in highly saline or humid conditions

Setup, Compatibility & Care

Installation requires basic hand tools such as a spanner or socket set, depending on the mating nut being used. Always ensure that the mating component has a matching M6 metric thread profile. To maintain the integrity of the bright zinc plating, avoid using excessive force or tools that may strip the thread, as mechanical damage can expose the base steel to potential corrosion. For long-term storage, keep these allthreads in a dry, low-humidity environment. If used in a damp area, consider applying a light machine oil to the exposed threads to further bolster the existing BZP finish against oxidation.
