RS PRO T-Handle Torx Keys

Introducing the range of RS PRO T-Handle Torx Keys. Designed with high-quality Chrome Vanadium Molybdenum steel, this Torx key offers a dual-function long arm and short arm, dependant on the application it is required for and can withstand high torque transmission from the user, especially when being used on stubborn fasteners. This Torx key is especially useful when working in tight spots with little space for movement because a higher amount of torque can be applied to the fastener without the risk of it rounding. The ergonomically designed bi-material handle offers superior comfort and lessens the fatigue for the user when working for extended periods of time, making this an ideal hand tool for professional and DIY users across a wide range of applications.

Features and Benefits:

• This high-quality short arm Torx key is suitable for use across a wide range of applications that require a Torx fastener
• Ergonomically designed dual-function handle that allows greater torque application and greater access in enclosed spaces
• Soft grip bi-material handle for optimum comfort and reduced user fatigue
• Made from high-quality Chrome Vanadium Molybdenum steel for increased durability and strength
• Matt chrome finish for greater corrosion resistance against harsh working environments
• Ideal hand tool for mechanics, engineers and DIY enthusiasts
• Torx keys available in a wide range of Torx sizes


Torx keys are most commonly used to tighten or loosen Torx fasteners used in a variety of different applications. Torx fasteners are well known for having a star-shaped blade that helps prevent ’cam-out’ or slipping and rounding the fastener, and as a rule, higher torque can be applied to these types of fasteners. With this in mind, it is essential for Torx keys to be able to withstand the amount of torque being applied by being more durable and stronger to ensure that it can loosen even the most stubborn fasteners or tighten up to the required torque spec. These keys are most commonly used by:

• Automotive mechanics
• Engineers
• Production and manufacturing operatives
• DIY enthusiasts

Are Hex keys and Torx keys the same?

The main difference between Hex keys and Torx keys is that Hex keys have 6 sides and are shaped hexagonally, hence their name. Torx keys are generally star-shaped with the benefit of adding greater contact points for the fastener, hugely reducing the risk of rounding the fastener, which can be a common issue when applying a large amount of torque. Because of this, Hex keys generally have greater difficulty when a large amount of torque is applied, and the fastener can easily be rounded.

What is the benefit of a short arm Torx key?

One of the benefits of using a short arm key is that with another Torx key situated on the short end, it means that access in enclosed spaces is made much easier and more manageable, making it a versatile hand tool for a range of applications. Additionally, when comparing this hand tool to a screwdriver handle, much less user effort is required by using a T-handle key because a greater amount of torque can be applied in a comfortable way for the user when tightening or loosening the fastener.
