Hucktainer Lockbolts

The commercial vehicle body manufacturing industry demands the highest standards of quality and durability. Manufactured from G.R.P. (Glass Reinforced Plastic), Hucktainer lockbolts not only ensure a longer vehicle lifespan but also improve vehicle security.

Hucktainer lockbolts are uniform, making them easily applicable to a wide variety of tasks. Installation does not require skilled labour, and the added option of a unique 'Star Lock' system allows installation to be carried out by one man rather than two. 

To make the lockbolts blend in with your side panelling, Hucktainers may be supplied with encapsulated colour heads. A low profile design ensures they remain unobtrusive within the vehicle.
