Square Drive Recess: This recess was invented by P.L. Robertson (founder of Robertson, Inc.) in 1908 and was the first production fastener with an internal recess.
The Phillips Recess remains very popular in the woodworking industry. It provides a much more positive fit than slotted screws and requires about 12 foot-pounds of pressure to keep the driver engaged in the recess. There is more cam out (driver bit slippage) that occurs when compared to square drive screws, which offer a more positive bit engagement. The cam-out was a part of the design feature to prevent overtightening of the fastener. This was described as a feature in the refinement Patent of 1949.
Torx is a patented brand name for a six-pointed drive pattern developed in 1967 by Camcar Textronic. The Generic name is Start Drive is commonly used instead of the trademarked Torx to identify the six-lobe drive system. Other companies have branded their own particular six-lobbed drive system, like Spax has a T-Star and a T-Star Plus. By design, the six-lobe drive resists Cam-Out better than Phillips (Phillips is designed to Cam-Out to prevent over-torquing) and slotted head screws.
Sizes are numbered and all start with a "T-" and range from 1 to 100. Starting with T-1 to T-10, they step up by increments of 1. From T-10 to T-45, they step up in increments of 5, and from T-50 to T100, they step up in increments of 10.
