FAQs

Are these screws suitable for outdoor use?

They feature a zinc-plated finish for basic corrosion protection, but are primarily recommended for indoor or sheltered environments.

Do I need any tools to install these?

No, the butterfly wing design is specifically meant for tool-free, hand-tightening.

What is the thread pitch for this screw?

These screws feature a coarse pitch of 1.25mm.

Can I use these on M8 nuts?

Yes, these are standard M8 screws and are fully compatible with standard M8 threaded nuts and holes.

What does the AN 265 standard mean?

It is an engineering standard that ensures the physical dimensions and structural integrity of the fastener are consistent with specific manufacturing guidelines.

Troubleshooting

The screw is difficult to turn after a few rotations.

Check for debris in the threaded hole or ensure the screw is not cross-threaded. Unscrew, clean the threads, and try re-inserting.

The butterfly wing is bending when tightened.

You are applying too much force. These screws are designed for hand-tightening only; do not use pliers to force extra tightness.

Setup, Compatibility & Care

To ensure the longevity of your Screws City butterfly wing screws, follow these guidelines:

  1. Compatibility: Ensure your mating component is threaded for an M8 bolt with a 1.25mm pitch. These will not function correctly in finer or coarser thread patterns.
  2. Installation: Simply insert the screw and turn clockwise using the butterfly wings until finger-tight. Ensure the threads are aligned correctly before turning to avoid cross-threading.
  3. Care: Keep the threads clean and free of debris. Since these are zinc-plated, avoid using them in high-humidity or outdoor salt-air environments, as the coating may fail over time. If they become stiff, a light coating of machine oil on the threads can improve performance.
