Magnetic Hex Nut Driver - 8mm Socket with ¼" Hex Shank

Magnetic Hex Nut Driver

The Magnetic Hex Nut Driver is an 8mm hex socket driver with a ¼" hex shank, designed for fast and repetitive setting and removal of nuts, bolts, and self-drilling screws. The magnetic hex socket retains the fastener during positioning and driving, keeping it seated correctly and reducing the risk of dropping fixings when working overhead or in awkward positions. Manufactured from high-grade steel for durability under sustained use. The 8mm size is the standard for driving self-drilling Tek screws, making this driver a daily-use tool for steel frame construction, roofing, cladding, and general site fixing work.

Why Choose the Magnetic Hex Nut Driver?

• Magnetic socket retention: The magnet in the socket holds the nut or bolt head in position during driving. This is particularly useful on repetitive fixing tasks and when working overhead or at height, where dropped fixings cause delays and safety risks.

• 8mm size for Tek screws: The 8mm socket is the standard size for self-drilling Tek screws, the most widely used fixing in steel frame construction, roofing, and cladding. Having the correct size driver eliminates the need to switch tools during fixing operations.

• ¼" hex shank: Fits directly into any drill, impact driver, or screwdriver with a ¼" hex chuck. No adaptor required.

• High-grade steel construction: Manufactured from high-grade steel for strength and durability under the repeated torque loads of production fixing work.

• Suits repetitive work: The combination of magnetic retention and direct ¼" hex fitting makes this driver suited to high-volume fastening tasks where speed and consistency matter.

Who Is This For?

This nut driver is for steel frame erectors, roofers, cladding installers, groundworkers, and general site operatives who regularly drive or remove 8mm hex-head fasteners including self-drilling Tek screws. It is equally suited to electricians, mechanical and engineering contractors, and facilities maintenance operatives who work with 8mm nuts and bolts as part of their daily tasks.

Typical Applications

• Driving self-drilling Tek screws in steel frame construction, roofing, and cladding

• Setting and removing 8mm hex nuts and bolt heads on structural and mechanical assemblies

• Repetitive fixing operations where magnetic retention speeds up the process

• Overhead fixing work where magnetic retention prevents dropped fasteners

• Any application requiring an 8mm hex drive on a ¼" hex drill or impact driver

How to Use

1. Insert the ¼" hex shank of the nut driver into the ¼" hex chuck of the drill or impact driver and lock it in place.

2. Place the 8mm hex fastener into the magnetic socket. The magnet will retain it securely during positioning.

3. Position the fastener on the fixing point and drive to the required depth or torque.

4. To remove a fastener, place the socket over the nut or bolt head and reverse the drill direction.

5. The magnet will retain the fastener in the socket after removal, allowing it to be placed or disposed of without dropping.

Safety

• Always ensure the drill or impact driver is switched off before fitting or removing the nut driver.

• Do not use this driver on fasteners larger or smaller than 8mm hex. An incorrectly sized socket can slip under torque and round off the fastener head.

• Inspect the socket and shank before each use for wear, cracks, or deformation. Remove from service if damage is found.

• Wear appropriate eye protection during all driving operations.

Maintenance

• Remove accumulated swarf and metallic debris from the magnetic socket after use. Metallic debris attracted by the magnet can prevent correct fastener seating.

• Check the magnetic retention strength periodically. A weakened magnet that no longer holds fasteners securely should be replaced.

• Inspect the ¼" hex shank for wear or damage regularly. A worn shank may not lock securely into the chuck.

• Store in a dry location to prevent corrosion on the socket and shank.

Frequently Asked Questions

Q: What is the Magnetic Hex Nut Driver used for?

 A: The Magnetic Hex Nut Driver is used for driving and removing 8mm hex-head fasteners including nuts, bolts, and self-drilling Tek screws. The magnetic socket holds the fastener in position during driving, making it suited to repetitive fixing work and overhead applications where dropped fasteners cause delays.

Q: Why is 8mm the most common size for site use?

 A: The 8mm hex socket is the standard drive size for self-drilling Tek screws, which are one of the most widely used fixings in steel frame construction, roofing, cladding, and general site assembly. An 8mm nut driver is a daily-use tool for operatives working in these trades.

Q: Will this fit my impact driver?

 A: Yes. The ¼" hex shank fits directly into any drill, screwdriver, or impact driver with a ¼" hex chuck. No adaptor is required.

Q: What does the magnet do?

A: The magnet inside the socket holds the nut, bolt, or screw head in position while you locate and start the fixing. This is particularly useful on repetitive tasks and when working overhead or at height, where a fastener that is not retained can fall and cause delays or a safety hazard.

Q: Can I use this driver for nuts and bolts as well as Tek screws?

 A: Yes. The 8mm socket drives any 8mm hex-head fastener including standard hex nuts, hex bolt heads, and self-drilling Tek screws. It is suited to both setting and removal operations.
