How do I use these torx tools ?

Question

I wanted to get a TORX screwdriver set so I can do stuff like on awkward shaped screws in appliances around the home and the car.

I got a recommendation to get the set here:

My confusion is how do I get a grip on the end of these bit ? Are you supposed to use them by hand by just grabbing the metal, or is another tool needed for them to clip in to ?

Thanks.

If the screws have a star shaped centre, then these are TORX or star screws. Most of the standard “screwdriver bit sets” contain 3 or more of the most popular size.If the heads have a small “pip” inside, they will be security screws. You will need a Security Bit Set. SCREWFIX sell a standard sized 33 bit set (D18983) at around £10, but for £15 you can get the 75mm long set (D95315). These are better for removing recessed screws.

You will also need a hex head driver handle. Like this one on the same web site.

The bits will also probably work in cordless electric screwdrivers.

Answer 2

These are just screw bits. Bring one to a local hardware store and they'll be able to supply the handle in which they fit.
