The conventional reaction arm is the standard accessory supplied with every HYTORC torque screwdriver. Its function is to absorb the reaction torque generated during the tightening operation, to prevent torsion on the operator or surrounding mechanical components. Made from high-strength steel, this arm is quick to install and adapts to a wide variety of industrial geometries. It is the basic solution for the majority of clamping applications in standardized environments.
The HYTORC safety handle is designed to provide an ergonomic and secure grip when using torque screwdrivers, while maintaining optimum distance between the operator and the torque zone. Its non-slip design, often combined with a hydrocarbon-resistant composite material, ensures perfect control of movements, even in extreme conditions. It also helps prevent tool positioning errors and significantly reduces the risk of injury in the event of a sudden reaction.
The WTCT (Washer-Type Cup Tool) sliding cup is a special accessory designed for tightening operations on calibrated washers, such as the HYTORC Washer system. It ensures precise axial retention of the tool when loading the screw, providing optimum centering between torque and preload. Thanks to its integrated sliding system, it compensates for variations in height or mechanical tolerances, while maintaining the linearity of the applied force. This cup is essential for assemblies with high requirements for flatness and controlled compression.
The HYTORC nut driver is an adapter specially designed to engage and hold in rotation the internal nuts used in HYTORC washer clamping systems. It ensures direct, backlash-free transmission of torque to the nut, while preventing slippage or misalignment. This accessory optimizes the precision of the applied torque, and enables smooth, fast operation in applications requiring simultaneous nut/washer clamping. It is widely used in industrial contexts subject to torque or tension certification.
The Z-Washer driver is a centering and locking tool developed specifically for tightening operations with Z-Washer self-reacting washers. It provides a rigid, perfectly coaxial connection between the torque tool and the washer, ensuring efficient internal torque reaction without the need for an external arm. The use of this driver is particularly recommended for applications in confined spaces, at height or in environments where the installation of an external reaction arm is technically impossible.
The wheel gun extension is designed for tightening wheels or mechanical components that are difficult to access in depth. It allows the torque application point to be offset, while maintaining the precision and efficiency of the transmission. Its reinforced body made of high-strength alloy guarantees perfect resistance to torsion, even at high torque. This extender is widely used in the automotive and rail industries, and for industrial fleet maintenance requiring rapid intervention on wheels or hubs.
The offset for offset tightening is an accessory that offsets the torque application point from the tool axis. It is indispensable when obstacles or complex shapes prevent direct alignment of the screwdriver with the fastener. Thanks to its angled head and internal mechanical transmission, it can reach bolts set back, at an angle or in mechanical channels. This system is essential for tightening in turbines, confined spaces or structures with lateral access.
The TPF reaction arm with sliding square is designed for modular use on different support points. Thanks to its sliding square, it can be adjusted in length to suit site configuration and fastener positioning. It also allows rapid repositioning of the reaction axis, making it a particularly appreciated tool for repetitive operations or on multi-screw flanges. Its robustness and ease of adjustment guarantee intensive use without compromising on safety.
The extended arm is an extension of the classic reaction arm, used to move the fulcrum to a greater distance, when the screw’s immediate environment allows no safe or accessible support. It can be used to cross obstacles or reach more distant fixed structures without compromising the tool’s stability. Constructed from reinforced steel, it is capable of absorbing high torques without flexing. It is particularly useful in congested installations, areas with high wiring density or complex mechanically-welded structures.

With 50 years of experience in the field of clamping solutions for industrial applications, we have encountered and resolved almost every problem imaginable.
Contact usIn the field of controlled industrial tightening, HYTORC torque screwdrivers are renowned for their reliability, power and modularity. To maximize their performance and respond to the specific constraints of each worksite, HYTORC offers a complete range oftechnical accessories designed to improve safety, ergonomics and accessibility of tightening operations. Whether working in standardized environments or in complex access configurations, each accessory plays an essential role in controlling torque and reducing operational risks.
The conventional reaction arm, supplied as standard with every tool, forms the basis of the reaction device. Robust, easy to install and compatible with all HYTORC screwdrivers, it effectively absorbs the torque opposed to tightening, guaranteeing tool stability and operator safety. For even greater control over working conditions, the safety handle provides an ergonomic grip and keeps hands away from the torque zone, reducing the risk of injury while improving manoeuvring comfort.
For operations requiring precise torque centering, such as with the HYTORC Washer system, the WTCT sliding cup ensures constant axial support, even in the presence of mechanical tolerances. This component is essential for maintaining force linearity when applying torque. Combined with this, the HYTORC Nut Driver guarantees a direct and reliable connection between the tool and the internal nut, ensuring optimum torque transmission without backlash or misalignment.
For users of the Z-Washer system, designed to operate without an external reaction arm, the Z-Washer driver enables fast, precise engagement. It facilitates operations in confined spaces or on structures where no external support is possible, while maintaining a high level of precision and safety.
The adaptability of the screwdriver is also ensured by devices for shifting or extending the torque application point. The wheel gun extension is ideal for reaching deep studs or bolts, such as those located in rims or hubs. Theoffset clamp, meanwhile, can be used to bypass physical obstacles or complex geometries, thanks to its internal angle transmission. These accessories are indispensable in environments with high mechanical density, such as aeronautics, railways or the processing industries.
Last but not least, HYTORC offers arms with specific geometries to adapt to the realities of the field. The TPF arm with sliding square is adjustable in length, enabling rapid support on different points without disassembly, ideal for multi-screw flanges or repetitive assembly. The extended arm, on the other hand, can be used to reach a distant support point by traversing congested or inaccessible areas.
Thanks to this comprehensive range of accessories, HYTORC torque screwdrivers become truly modular platforms, capable of adapting to all the constraints of heavy industry, energy maintenance or infrastructure sites. Operator safety, torque control, increased productivity: each HYTORC accessory is designed to transform a technical constraint into a performance lever.
