Problem & Solution
Dropping tiny screws into hard-to-reach places like vehicle engine bays, furniture joints, or equipment housings is a major source of frustration for anyone doing assembly or repair work. Weak standard bits often fail to hold fasteners firmly, leading to dropped hardware, scratched surfaces, and lost time.
This compact 6.35mm (1/4 inch) magnetic coil collar provides a simple and effective fix. By sliding directly onto standard hex bits, it multiplies the magnetic attraction to grip screws tightly during alignment and driving. When magnetic force is no longer needed—such as when working around sensitive metal filings—the built-in demagnetizing function resets your bit in seconds.
Who Is It For?
This tool is designed for mechanics, equipment repair technicians, woodworkers, and DIY enthusiasts who frequently use standard 1/4-inch hex drill bits and power screwdrivers.
It is also ideal for home improvement hobbyists looking for an inexpensive accessory to streamline furniture assembly, drywall installation, and general maintenance projects.
Key Features
- High-Intensity Neodymium Magnetic CoilHolds screws and bolts firmly against the bit tip, preventing dropped fasteners during one-handed or overhead driving.
- Universal 6.35mm (1/4") Hex FitSlides directly onto standard power driver bits without requiring extra adapters or tools.
- Dual Magnetize and Demagnetize CapabilityAllows fast transitions between strong magnetic grip and neutral magnetic states whenever task requirements change.
- Impact-Resistant Collar CasingEncases the internal magnetic core to withstand drop impacts and everyday wear in tough workshop environments.
- Ultra-Compact Lightweight ProfileAdds minimal bulk and weight, ensuring your driver bit remains balanced and easy to maneuver in tight spots.

FAQ
It is specifically engineered to fit standard 6.35mm (1/4 inch) hex shank driver and screwdriver bits.
Pass the bit tip across the designated demagnetizing section on the outer casing to remove residual magnetic charge.
No, the collar fits snugly around the shank, adding magnetic pull without destabilizing the bit during rotation.
