A set screw for use in association with a spinal implant system, comprising:

• a threaded base portion extending along a longitudinal axis, said threaded base portion formed of a first material;
• a proximal head portion extending axially from said threaded base portion;
• and
• a friction member extending from a distal end of said threaded base portion, said friction member including a projection extending from an outer surface, said friction member formed of a second material different from said first material,
• wherein said set screw includes a first passage extending from said proximal head portion to a portion of said threaded base portion and a second passage extending from said first passage to a distal face of said threaded base portion, said first passage having a first width and said second passage having a second, reduced width, said second passage comprising a groove, said projection being positioned in said groove, and wherein said friction member extends from beyond said distal face, through said second passage and into said first passage.
