Crane Fasteners

When our Crane customers are designing and building the latest technology in their product, safety and security is the top priority. Dokka Fastener products are built with safety and security as the cornerstones of our processes. Our fasteners are “Forged From Integrity” to withstand the extremely rigorous applications that our customers require.

For over 100 years, we have manufactured world class hex bolts, double-ended studs, and threaded rod for customers around the world – customers who build the tallest, strongest, most complex craning systems. These customers turn to us to fasten these incredible structures together.

Our specialty is slew-ring bolts manufactured on our fully automated robotic production cells, hardened in-house and supplied complete with 3rd party inspection to satisfy the lifting appliance requirements of certification bodies as DNV, Lloyds and ABS among others.

Further separating ourselves from the competition, we can also provide inventory management on a global basis, utilizing the local Würth logistics facility.
