Extended Product Information

FAQs

Are these bolts suitable for coastal environments?

While the bright zinc plating provides excellent corrosion resistance, we recommend checking them periodically in highly saline, salt-spray environments.

Can I use these for timber-to-timber joining?

Yes, these are excellent for joining timber products, provided the material thickness allows the bolt to pass through and the nut to be tightened fully.

Do I need special tools to install these?

No, standard screwdrivers and a wrench or pliers to hold the square nut are sufficient for installation.

Is the zinc finish safe for food-contact surfaces?

No, these bolts are intended for construction and structural use, not for food-contact applications.

How do I choose the correct length?

Select a bolt length that allows the threaded portion to pass fully through your materials with enough room for the square nut to be threaded on securely.

Troubleshooting

Bolt is difficult to insert into the hole

Verify that your drill bit was 1mm larger than the bolt diameter; re-drill if the hole is too tight.

Nut spins when tightening

Ensure the square nut is properly seated in the recess or held firmly with a wrench to prevent rotation.

Rust appearing on the bolt head

Check if the zinc plating was scratched during installation and apply a rust-inhibiting coating if necessary.

Pros and Cons

Pros

  • High resistance to corrosion due to zinc plating
  • Low-profile head reduces snagging
  • Includes essential square nuts for immediate use
  • Highly durable for outdoor exposure
  • Easy to install with standard tools

Cons

  • Requires precise drill sizing for best results
  • Finish may degrade if scratched deeply
  • Not intended for high-torque industrial machinery applications

Setup, Compatibility & Care

To achieve the best results, always measure the diameter of your bolt and select a drill bit that is 1mm larger. This clearance ensures ease of insertion without compromising the structural hold of the fastening. For exterior applications, periodically inspect the bolt heads for signs of heavy abrasion; if the zinc finish is compromised, a touch-up of cold-galvanizing spray can help maintain protection. Store these bolts in a dry environment to keep the threads clean and free from premature oxidation before they are deployed.
