Tools for RVers: Two handy screwdrivers

Chris Dougherty, Certified RV Technician, submitted this article while he was serving as’s technical editor.

A standard throughout the RV industry, Robertson or square head screws hold almost everything in an RV together, from cabinetry to outside trim. Robertson screws are used because the screws hold exceptionally well to the screwdriver or bit that they’re being installed with.

A Robertson or square tip screwdriver is a must for any RV tool kit. Sized in #00 to #4, and Scrulox 8,  #2 is most often seen in RVs, and the Scrulox 8, recognized by its 8-sided driver recess, is seen commonly in utility trailers. The Scrulox 8 has a hi-torque bit of its own but will work with the standard #2 bit.

I have both a manual multi-tip screwdriver with square tip in my toolbox as well as a good screw gun with multiple tips that I take on trip. I almost always use the gun or drill over the manual driver. Some RV screws can be upwards of 3-4 inches long; however, those types of structural screws are seldom removed by an RVer on a trip.

“Structural Screws” That funny!

consider adding a spare set of the screws also. when you drop them, they develop legs and crawl under your most difficult space to hide. they will crawl out in the dark, so you can step on them with your bare feet.
