45 lb Bar Magnets with Countersunk Hole and Screws, Pack of 6 or 12

Holding a jig, bracket or tool steady usually means a clamp and a spare hand. These rectangular magnets have a countersunk hole and come with screws, so they can be fastened to a bench or jig and hold steel parts in place. They suit workshop, garage and DIY assembly work.

Screw-in bar magnets for bench and jig work

✅ Fixes where a clamp will not fit The countersunk hole takes a screw, so the magnet stays on the bench or jig.

✅ Keeps small tools within reach Screw a row above the bench so spanners and pliers sit where you work.

✅ Two bar lengths in the range 40 mm and 60 mm bars cover compact brackets and longer steel rails.

✅ Screws arrive with the magnets Each pack includes screws for the countersunk holes, so mounting can start straight away.

✅ Pick six or twelve A small job needs one pack of six; a full bench row takes twelve.

Assembly benches are the obvious home: a magnet holds a steel bracket while you line up the second bolt, or keeps a spanner where your hand expects it. In a garage, a row along a shelf edge works as a tool strip.

Fitting is one screw per magnet. Mark the position, drive the screw through the countersunk hole until the head sits flush, then bring the steel part up to the face. Because the head sits below the surface, the magnet face stays clear for contact.

The two lengths are not interchangeable in use: a 60 mm bar gives more contact along a rail, while the 40 mm version fits a narrow bracket or a tight corner. The 45 lb figure is the maker's pull rating; actual holding depends on the steel surface and how the load pulls on the magnet, so test the setup before relying on it.
