What You Need To Complete The Job

Frequently Asked Questions
What size screw does a 3/8 inch hex socket drive?
A 3/8 inch hex socket drives hex head screws and bolts with a 3/8 inch hex head. That covers a range of roofing screws, self drilling screws and machine bolts used on metal roofs and gutters. Match the socket size to the screw head for a full grip without rounding.
Does the magnet work with an impact driver?
Yes. The built-in magnet holds the screw on the bit while you position it, and it keeps working under the vibration of an impact driver. That reduces dropped screws when you are working on a roof or at an angle where a second hand is not free.
What is the difference between this and a nutsetter?
A hex socket is a single size driver that fits one hex head size, while a nutsetter set covers several sizes in one pack. Both drive hex head screws and both hold the fastener with a magnet. If you work across many screw sizes, a nutsetter set is a handy companion to the individual sockets.
Is this socket hardened for impact use?
The socket is built for driving fasteners with an impact driver, and the listing describes superior head design and optimum hardness. As with any impact accessory, check the bit for wear and replace it once the corners round off so the screw head stays in good condition.
