Magnetic socket bit 1/4 x 50 mm: 869/4 M

The magnetic part keeps the bolt or screw in the socket while you position it. This is useful for overhead work, in tight spaces or in places where you can only reach with one hand. Always check the size of the socket itself before ordering, as it must match the hex of the bolt or nut you are using.

What work is a magnetic socket bit suitable for

A socket bit with a 1/4 inch drive is used in installation, assembly and maintenance, including for sheet metal screws and machine screws with a hex head. Because the drive fits in a standard bit holder or screwdriver, you work faster than with a separate ratchet or open-ended wrench. This bit is usually not intended for heavy bolts with a high tightening torque; in that case a larger socket wrench or impact wrench is the better choice.

Length and drive: what 1/4 inch at 50 mm means

The 1/4 inch drive is the common size for bits and bit holders. This means you can use the bit in many different machines and handles. The length of 50 mm gives extra reach, so you can also get to bolts that sit deeper in a structure or are recessed. A shorter bit is more stable, a longer bit reaches further, so choose the length based on where you need to work.

Practical tips for use and maintenance

Place the bit straight on the bolt and turn with even pressure, so the socket does not sit at an angle or get damaged. Wipe metal shavings off the magnetic part, as they stick to it easily and can affect the fit. Store bits dry and separate from other tools, so they do not rust or get damaged.

Frequently asked questions

Does this bit fit in a cordless screwdriver?

Yes, if the machine has a bit holder or socket for 1/4 inch hex bits. This is the case with most screwdrivers.

What is the magnetic part for?

It holds the bolt or screw in the socket, so you can position it more easily, even in hard-to-reach places.

How do I know which socket size I need?

Measure the hexagon of the bolt or nut, or check the size marking on the matching fastener, and choose a socket of the same size.
