Extended Product Information

FAQs

What does the 8.8 grade represent?

The 8.8 grade refers to the tensile strength and yield strength of the steel, indicating that these bolts are engineered for high-strength, heavy-duty applications.

Are these bolts suitable for outdoor use?

Yes, they feature a corrosion-resistant finish, making them suitable for many outdoor applications, though regular maintenance is recommended.

Does this set include washers?

Yes, the kits are designed as complete fastening solutions, typically including the necessary nuts and washers for a secure installation.

Can I use these for automotive repairs?

Yes, their high tensile strength makes them suitable for various automotive fastening requirements, provided the size matches your specifications.

Should I use lubricant on the threads?

A light coating of appropriate lubricant can assist with smooth installation and further prevent corrosion in the threads.

Troubleshooting

Bolt is difficult to screw into the pre-drilled hole

Verify that the thread pitch and diameter are perfectly matched and ensure no debris is trapped in the hole.

The bolt head is rounding off during tightening

Ensure the socket or wrench is the correct size and fully seated on the head before applying force.

Signs of surface oxidation appearing

Clean the area with a wire brush to remove debris and apply a corrosion-inhibiting spray.

Pros and Cons

Pros

  • High tensile strength suitable for heavy-duty loads
  • Corrosion-resistant coating for increased longevity
  • Comprehensive kit includes necessary nuts and washers
  • Precision-machined for consistent fit and reliability

Cons

  • Requires specific tool sizes for proper hex head engagement
  • Not suitable for marine-grade or highly acidic environments without additional protection
  • Limited to standardized mechanical sizing

Setup, Compatibility & Care

Proper installation is vital for the performance of high-tensile hardware. Ensure you are using the correct metric spanner or socket size that matches the bolt head. Always check that the thread pitch matches your pre-drilled holes or mating parts before driving the bolt to avoid thread stripping. When working in exterior environments, it is recommended to periodically inspect the bolts for signs of finish wear. If the silver protective coating is scratched during installation, applying a light coating of metal-safe lubricant can help maintain the corrosion resistance of the steel.
