FAQs

What does the Grade 8.8 rating mean?

Grade 8.8 refers to the tensile strength of the steel; it is a high-strength fastener commonly used in structural and mechanical engineering applications.

Can these bolts be used outdoors?

Yes, the white finish provides corrosion resistance, though for extreme marine or acidic environments, specialized stainless steel might be preferred.

Are the nuts and washers included?

Yes, the Unifix Hex Set is a complete solution that includes DIN933 bolts along with DIN125A washers and DIN934 nuts.

Do these bolts have full or partial threads?

The DIN933 standard specifies that these bolts are fully threaded along the length of the shank.

What tools are required for installation?

You will need a standard metric wrench or a socket set that corresponds to the head size of your specific bolt variant.

Troubleshooting

Bolt is difficult to thread into the hole

Check that the threads are free of debris and ensure the bolt diameter and pitch match the receiving hole exactly.

Head of the bolt is rounding off during tightening

Ensure you are using the correct size metric tool and that it is fully seated on the bolt head before applying torque.

Bolt feels loose after installation

Verify that a washer was used correctly and check if a lock washer or thread-locking compound is needed for high-vibration environments.

Pros and Cons

Pros

  • High tensile strength suitable for structural applications
  • Comprehensive kit includes bolts, nuts, and washers
  • Industry-standard DIN specifications ensure compatibility
  • Corrosion-resistant finish enhances longevity

Cons

  • Specific to DIN933 threaded standards
  • Finish may scratch under excessive torque
  • Requires proper tool sizing to prevent fastener damage

Setup, Compatibility & Care

To ensure proper installation, always use the included DIN125A washers to distribute the load evenly and prevent surface damage to the substrate. When tightening, use a metric wrench or socket set that perfectly matches the hex head to avoid rounding the edges of the bolt. For maintenance, keep the fasteners in a dry environment if possible to preserve the white protective coating. If the bolts are exposed to extreme outdoor conditions, consider applying a light anti-seize lubricant to the threads during installation to make future removal easier and prevent potential galling.
