MALCO MSHMLC 4-inch Cleanable Reversible 1/4-inch and 5/16-inch Hex Driver (1-Pack)

This was a replacement, lost mine. This is a great tool to have fits most small self tapping screws with a bolt head.

I got this for use as a nearly permanent attachment in an impact driver. This is the exact size (both sizes) nut driver needed for most of the fasteners used in HVAC, and as a dual function tool it saves a lot of time and hassle. Removing the socket will expose the magnetic end, allowing easy cleanout of the ferromagnetic debris that tends to build up in magnetic nut driver bits. It lives in my impact driver mainly for use in removing panels from the condenser assembly or air handler -- where removal of multiple screws is required. In the impact driver, it is a bit too short to get to some internal fasteners in a split system, such as the ones holding internal components like the capacitor strap, contactor, or transformer.

These are great…Must have if you do hvac.

Works much better than the Christmas tree bits if you know what I’m talking about

Works great

It's great, used it for about a year everyday as a sheet metal worker. My only complaint is the magnet. once it comes out you might as well throw it away

The Malco 1/4 5/16 magnetic bit is easily the best on the market, with amazing versatility the magnet is crazy strong and lasts a very long time compared to others like Klein. Fits perfect in any tradesman bag

These things with 1) a 1/4 hex handle and 2) a low voltage (10-12VDC) hex driver make all sorts of home appliance repair a lot easier. Not just easy to use, but the design makes wiping away the crud pretty mindless. Other nut setter designs clog up and the internal magnet keeps the metal crud in there - not so with this design. Doing my own repairs is a lot easier with these, and doing my own repairs saves thousand of dollars too. Easy to justify.
