Top Fasteners | Fastening Solutions Provider
LOCKBOLTS AUSTRALIA
Lockbolts are high-strength permanent fastening systems designed for demanding applications where conventional nuts and bolts may loosen under vibration, impact, or heavy loads. Consisting of a pin and collar, lockbolts are installed using specialised hydraulic or pneumatic tools that swage the collar onto the pin to create a secure, maintenance-free joint.
Unlike traditional bolted connections that rely on thread friction, lockbolts provide consistent clamp force and exceptional resistance to vibration, fatigue, and shock loading. This makes them a preferred fastening solution for industries such as transport, mining, construction, rail, manufacturing, and heavy engineering.
Top Fasteners supplies a comprehensive range of lockbolts throughout Australia, including high-strength lockbolt pins and collars designed to deliver long-term reliability in the most demanding environments.

Frequently Asked Questions
What are lockbolts used for?
Lockbolts are used in high-strength structural applications where permanent fastening, vibration resistance, and consistent clamp force are essential. They are commonly used in transport, mining, construction, rail, and heavy manufacturing.
How are lockbolts different from conventional bolts?
Unlike conventional bolts that rely on threaded nuts, lockbolts use a pin and collar that are permanently swaged together during installation. This creates a stronger, maintenance-free joint with superior resistance to vibration and loosening.
Are lockbolts permanent?
Yes. Lockbolts are designed as permanent fasteners. Removing them typically requires grinding, drilling, or cutting.
What industries use lockbolts?
Lockbolts are widely used in transport, rail, mining, construction, heavy engineering, manufacturing, agriculture, and infrastructure projects.
What tools are required to install lockbolts?
Lockbolts are installed using specialised hydraulic or pneumatic lockbolt tools fitted with the correct nose assembly for the specific fastener.
Do you supply lockbolts Australia-wide?
Yes. Top Fasteners supplies quality lockbolts, including high-strength lockbolt pins, collars, installation tools, and related fastening products to businesses throughout Australia.
