Magnetic socket bit 5/16 inch x 50 mm, 869/4 M

On this page you will find the dimensions and the price of this item. Below you can read what you use this socket bit for, why the magnet is handy and what to look out for before you order.

For which applications do you use a socket bit?

A socket bit combines the function of a socket wrench with the speed of a bit. You click it into a bit holder or directly into the machine and tighten hex screws or bolts faster than with a ratchet. This is handy in construction, installation and renovation, where you regularly need to fit many fasteners one after another. The size 5/16 inch corresponds to approximately 8 mm across flats, but always check the size of the head of the fastener itself.

Advantages of a magnetic socket bit of 50 mm

The magnet holds the screw or bolt in place, so you can work with one hand and are less likely to drop something, for example overhead or in hard-to-reach places. The length of 50 mm gives extra reach, so you can also get to fasteners that sit a bit deeper. The magnetism only works on magnetic material, such as steel; with stainless steel or other non-magnetic materials the bit holds the screw less well.

How to choose the right socket bit

First look at the size of the head of the fastener and at the connection of your machine or bit holder. Also consider the required length and whether a magnetic version adds value for your work.
