1. Every Handyman Should Know Fastener Types
In our March 2011 issue of Canadian Home Workshop, we have an article called “50 Things Every Handyman Should Know.” Item No. 1 in that list is fastener types.
A real handyman does not say, “Pass me the star screwdriver.” Or, “Not the cross but the square one.” That cross-shaped head that strips so easily is a Phillips. When you pick up the square-shaped one, your heart should fill with patriotic pride and you should thank Mr. Peter L. Robertson for his wonderful invention. The handles of Robertson screwdrivers are colour-coded:
Colour Screw Types
Orange (#00) No. 1 and 2
Yellow (#0) No. 3 and 4
Green (#1) No. 5, 6 and 7
Red (#2) No. 8, 9 and 10
Black (#3) No. 12, 13 and 14
While researching this tip, I came across a very cool write-up of different screw types. Most important, my fellow patriotic fastener users, know the difference between a Robertson and those other, poser square-drive fasteners: Robertson has a slight taper that allows a bit to hold onto the screw and prevent cam-out.
