RS PRO 1/4" Drive Hexagon Socket Bits

Introducing 1/4" drive hexagon socket bits from our own brand RS PRO, a selection of high quality and reliable hexagon bit sockets to choose from, designed for use with wrench and driving tools with a 1/4" drive.

The hexagon bit is manufactured from chrome vanadium molybdenum and is fixed to the socket, providing a strong and reliable wrench socket accessory that can be used for various tasks to a high standard. The sockets are manufactured from chrome vanadium, providing a durable socket that can withstand extensive use in a range of working environments. The sockets also feature a mirror chrome finish offering a stylish and professional aesthetic whilst offering excellent corrosion resistance properties.

RS PRO 1/4" hexagon socket bits are available in a variety of metric sizes and make an excellent addition to any socket set, ideal for applications requiring nuts and bolts with a hex socket recess to be tightened and loosened by hand. The hexagonal bit head will fit securely inside, similar to a hex key, enhancing the grip and torque whilst allowing you to work quickly with ease.

Socket bits and socket accessories offer increased versatility without the need for the user to purchase new and more expensive tools, making such accessories a cost-effective solution when requiring tools that need to be used on various applications. It makes it easy to maximise the potential usage of ratchet spanners, extension bars, sockets and impact / power tools.

Sockets and socket accessories are commonly used in a wide range of applications including:

• Mechanical / Automotive
• Construction
• Engineering
• Maintenance and repair


Why use a socket wrench and hexagonal socket bit rather than a hex key?

Although they can be used for similar applications, using a socket and wrench has many advantages. The use of interchangeable sockets ensures that only one wrench is required to work with various sized fasteners, saving both time and money. The 6-point head also ensures a secure and reliable connection to the fastener with each point producing a strong grip with increased torque. The combination of a wrench and socket bit provides a much more versatile hand tool that can be used in a wide range of applications.
