Frequently Asked Questions

Do I need to pre-drill holes for lag screws?

Yes—lag screws should be installed in pre-drilled pilot holes to avoid wood splitting & ensure maximum grip.

Are galvanised lag screws suitable for outdoor use?

Absolutely. Our hot-dip galvanised lag screws are designed to resist rust & corrosion, making them ideal for outdoor timber structures.

What’s the difference between a lag bolt & a regular screw?

Lag bolts have thicker shanks & are designed for high-strength load applications, unlike general-purpose screws which are smaller & less durable.
