Onshore and Offshore Wind Turbines
Fast. Safe. Expertly bolted.
HYTORC offers field-proven, scientifically validated bolting solutions for onshore and offshore wind turbines. Our high-torque bolting technology delivers reliable, repeatable and weight-optimized results while improving workplace safety, including on safety-critical bolted joints.
From design and installation to operation and maintenance, HYTORC is your reliable partner for every wind turbine bolting application.
Design
and Production
Our bolting solutions improve wind turbine stability from the design phase onwards. Fully load-bearing ISR flange nuts allow tower joints to be tightened to a higher, consistent preload level using a controlled and documented process. Their compact design also allows fasteners to be positioned closer together and nearer to the tower shell.
Installation
and Assembly
HYTORC bolting technology is engineered for efficiency and workplace safety. Especially on large bolted joints up to M80, our Trolley Set enables fast assembly with minimal physical effort. This reduces strain on installation crews and shortens erection times.
Operation
and Maintenance
Low-maintenance bolted joints reduce service intervals and maintenance costs. Our controlled and repeatable tightening processes achieve maximum preload with minimal scatter, even in exposed locations such as splash zones and subsea applications.
HYTORC Bolting Solutions for Wind Turbines
Foundation Bolting
With suitable bolt tensioners, HYTORC bolting technology provides stable and secure wind turbine foundations, including subsea applications with bolt sizes up to M80. One example is the HYTORC Nut, proven for 30 years. It allows bolted joints to be tensioned quickly and safely by remote control, without torsional or side loads, to an exact and repeatable preload.
Recommended Fastener: HYTORC Nut
Tower Bolting
The innovative HYTORC Trolley Set enables fast, documented tightening of tower flange joints using bolt sizes M52 and larger, achieving the highest possible consistent preload level. Active support reduces physical strain on technicians, while shorter crane times improve efficiency during turbine installation. Flexible hydraulic bolting solutions are also available for smaller bolt sizes.
Recommended Tools: MXT+ and STEALTH
Nacelle and Drivetrain
Low-maintenance bolted joints in the wind turbine nacelle reduce service intervals and improve operational reliability.

MXT+, STEALTH, LITHIUM SERIES II and the Washer-System
Bolt Inspection
Pre-tightened bolted joints must be inspected at regular intervals. HYTORC bolting technology can determine and simultaneously document the residual torque required to continue rotating an installed fastener. The measurement uses the further-rotation method and is recognized under VDI/VDE 2645 Part 3 for process capability testing.
Safe Bolting
Workplace safety is a top priority at HYTORC. We provide comprehensive advice and solutions to improve safety both in production and in the field.
Documented Bolting and Tightening Methods
Our controlled, documented tightening methods reduce operating, service and maintenance costs over the long term. Seamless documentation avoids costly inspections and has been shown to extend maintenance intervals.
Training and Qualification
Failure or unintended loosening of bolted joints can cause hazardous wind turbine outages and high costs. Qualified, well-trained personnel significantly reduce this risk. Through our cooperation with the Akademie der Schraubverbindung (AdSV®), your employees receive systematic training in bolting technology tailored to their requirements.
AdSV® is a certified, independent training provider offering comprehensive qualifications to maximize plant safety and workplace safety.
