Fast Thread Bolting System
Can’t find what you’re looking for?
TTC have developed the fast-thread socket now familiar to many customers as a fast and efficient method of fixing tunnel segments.
Available in a range of lengths and diameters to suit different applications and the line loads exerted by gasket sealing systems.
Our bolts are manufactured in the UK to customer’s individual requirements. You can specify the length, diameter, steel grade, and choose from a range of surface finishes (e.g. galvanised, bright zinc plating etc.). They can be supplied in grade 4.6 and 8.8.
