Frequently Asked Questions

What is a magnetic nutsetter?

A nutsetter is a bit with a socket shaped head that fits over a hex nut or bolt head, so you can drive it with a power tool. The magnetic version holds the fastener on the bit, which lets you place and start a nut one handed without it dropping off before it bites the thread.

What size nut does a 5/16 inch nutsetter fit?

A 5/16 inch nutsetter fits hex nuts and bolt heads across the 5/16 inch (7.94mm) size range, which covers common fasteners used in assembly and maintenance work. Match the nutsetter to the fastener size for a snug fit that will not round the corners off the nut.

Why use a 300mm length?

The 300mm length gives reach for nuts set deep in housings, behind panels and in recessed pockets where a short nutsetter cannot get the driver close. It also keeps your hand further from the work, which can help in confined spaces. For everyday work the 150mm version is the usual first pick.

Can I use a magnetic nutsetter without the magnet?

The magnet is part of the nutsetter and cannot be removed, but you do not have to rely on it. The magnet simply holds the fastener on the bit while you position it, which is a help when starting nuts one handed. If you prefer, you can still drive nuts the usual way and the magnet just keeps them from dropping off.
