<p>The present invention provides a modified interlocking solid composition stick for applying to steel surfaces that are in sliding or rolling-sliding contact. The modified stick comprises a body member with four sides, a first end and an opposed second end, and a nib member attached to the first end of the body member, the nib member having four sides connected by substantially curved side edges. The second end of the body member contains a cavity with substantially curved side walls dimensioned to snugly receive a nib member of a corresponding interlocking solid stick. To reduce the likelihood of failure of the nib or cavity, the dimensions of the nib are optimized such that a length of one side of the nib member (nl) and a length of the side of the body member (l) in the same plane has a ratio nl/l from about 0.6 to about 0.75.</p> |
