FAQs

What material are these bolts made from?

These bolts are made from premium A2 304 stainless steel, known for its excellent corrosion resistance and durability.

What does ISO 7380 mean?

ISO 7380 is an international standard that specifies the dimensions and requirements for button head socket screws, ensuring precision and interchangeability.

What size Allen wrench do I need for these M8 bolts?

For M8 bolts, you will typically need an 8mm Allen wrench (hex key).

Can these bolts be used outdoors?

Yes, the A2 304 stainless steel construction makes them highly resistant to corrosion, making them suitable for outdoor applications.

Are these bolts fully threaded?

Yes, these bolts feature a fully threaded shaft for maximum thread engagement.

What applications are these bolts best suited for?

They are well-suited for machinery, automotive, construction, industrial applications, and general DIY projects where durability and corrosion resistance are important.

How should I clean these stainless steel bolts?

Clean with a damp cloth and mild soap if necessary. Avoid abrasive cleaners that could scratch the surface.

Troubleshooting

Bolt does not thread smoothly

Verify that you are using the correct M8 threaded hole or nut and that the threads are clean and undamaged. Ensure you are threading the bolt straight and not at an angle.

Allen wrench feels loose or slips

Confirm you are using the correct size Allen wrench (typically 8mm for M8 bolts). Ensure the wrench is fully inserted into the socket.

Bolt head spins but doesn't tighten

The threads in the mating component (nut or tapped hole) may be stripped or cross-threaded. Inspect the mating threads for damage. If damaged, the component may need repair or replacement.

Visible rust or discoloration

Although stainless steel is corrosion-resistant, extreme conditions can cause surface staining. Clean with a non-abrasive cleaner. For severe staining, consult specialized stainless steel cleaning guides.

Pros and Cons

Pros

  • Excellent corrosion resistance due to A2 304 stainless steel.
  • High durability for long-term use in demanding conditions.
  • Meets ISO 7380 standards, ensuring quality and interchangeability.
  • Easy to install and remove with standard Allen wrenches.
  • Versatile for use across multiple industries and project types.

Cons

  • Specific metric sizing (M8x70mm) may not fit all applications.
  • Stainless steel can be softer than some other metals, potentially affecting thread stripping if over-tightened.
  • Requires a corresponding Allen wrench for installation/removal.
  • May be more expensive than standard carbon steel fasteners.

Setup, Compatibility & Care

Setup: To install, select the appropriate size pre-drilled hole and thread the bolt into the corresponding tapped hole or nut. Use a compatible Allen wrench (hex key) of the correct size to tighten the bolt until snug. Avoid over-tightening, which can damage the threads or the mating material.

Compatibility: These bolts are metric, M8 size with a 70mm length, and conform to ISO 7380 standards. Ensure compatibility with your existing metric M8 tapped holes or nuts and any required mating components. An 8mm Allen wrench is typically required for this size.

Care: While highly corrosion-resistant, prolonged exposure to harsh chemicals or de-icing salts may require occasional inspection. Clean with a damp cloth if necessary. For long-term storage, keeping them in a dry environment will preserve their finish and function.
