RAD accessories are the attachments that change what a RAD tool can reach and how it reacts against the joint. The right reaction arm or gearbox often makes the difference between a tool that fits the application and one that does not, so it is worth specifying them alongside the tool rather than afterwards. Everything here is genuine RAD equipment, matched to the RAD Torque Systems range we supply.

Reaction Arms

Every torque tool has to react its output against something. The reaction arm is what transfers that load safely into an adjacent nut, flange or structure instead of into the operator. Standard and custom arms are available, and we can fabricate to suit an awkward joint where nothing off the shelf lines up correctly.

Offset Gearboxes and Nose Extensions

An offset gearbox moves the drive away from the body of the tool so it can enter a restricted space, and a nose extension pushes the drive further forward to reach a recessed fastener. Between them they solve most access problems on a battery or pneumatic tool. Where clearance is still the limiting factor, a low clearance hydraulic wrench is the better answer.

SDM Gearboxes

SDM gearboxes increase the torque output of the tool they are fitted to, letting one platform cover a wider range of joints without buying a second tool. They are a cost effective way to extend a fleet, particularly where only a handful of joints sit above the standard range of the tool. See also our torque multipliers for manual applications.

Servicing and Certification

Accessories affect the torque actually delivered at the joint, so a tool and its gearbox should be calibrated together as a set. We calibrate, service and repair in house and issue certification on completion.

RAD Accessories FAQs.

What is a reaction arm and why do I need one? +

A reaction arm absorbs the torque the tool generates and transfers it safely into an adjacent nut, flange or fixed structure. Without the correct arm the load has nowhere safe to go, which is both dangerous for the operator and bad for accuracy. Every RAD tool should be used with a suitable reaction arm.

What does an offset gearbox do? +

It moves the drive square away from the main body of the tool so the tool can get into a restricted space. It is the usual fix when a fastener is reachable in principle but the body of the wrench fouls something nearby.

When would I use a nose extension? +

When the fastener sits recessed inside a housing or below surrounding structure, so the drive needs to reach further forward than the standard tool allows.

Do SDM gearboxes increase torque? +

Yes. An SDM gearbox raises the torque output of the tool it is fitted to, which lets a single tool cover a wider range of joints. It is often cheaper than buying a second, larger tool for a small number of high torque fasteners.

Do accessories need to be calibrated with the tool? +

Yes. A gearbox changes the torque delivered at the joint, so the tool and accessory should be calibrated together as a set. We do this in house and issue certification.
