Magnetic self-tapping screws

Magnetic tips for a screwdriver simplify driving self-tapping screws into surfaces made of various materials.

There are several types of such devices, each designed for a specific type of fastener head: slotted or cross-recess, as well as a hollow cylinder with a hex socket. The latter option is convenient when installing roofing and wall coverings.

In terms of design, the tip can take the form of:

• a holder with a bit holder rotating along the axis and a magnet on the end part;
• a universal sleeve with a magnetic ring that fits onto the drive shaft with an extended shank;
• a coupling with three elements — a collet chuck, a magnet to hold the self-tapping screw, and a stop.

Each type comes with a set of bits for different self-tapping screw modifications and types of working materials. A tip with magnetic properties holds the fastener across the full surface of the head, so the self-tapping screw does not need to be held by hand.
