It's easy with the Skil Screw Assist!

https://goo.gl/dcZVmg Models 2016 (12V) and 2017 (14.4V) come with Skil's unique Screw Assist, which holds the screw firmly ready for driving. It's ideal when you're working with one hand -- in a corner or overhead. These new cordless drill/drivers are compact and easy to handle. So they're ideal for all those everyday DIY drilling and fastening jobs in wood, composite materials and sheet metal. There's a handy trigger-operated variable speed control and an electronic brake. The 19-position clutch allows precisely controlled screwdriving, and there's an extra full lock-up setting for drilling. Changing of drill and screwdriver bits is fast and effortless, thanks to the 10 mm keyless chuck. You can use these new drill/drivers with a wide range of drill and bit sizes and types.
