The present invention provides a modified interlocking solid composition sti ck for applying to steel surfaces that are in sliding or rolling-sliding contact. T he 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 membe r having four sides connected by substantially curved side edges. The second end of t he body member contains a cavity with substantially curved sidewalk 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 (1) in the same plane have a ratio (nl) from about 0.6 to about 0.75.
