A pin member for a fastener includes an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the bearing surface of the head, and a threaded portion located at the second end of the elongated shank. Either or both of the bearing surface of the head or the outer surface of the cylindrical shank portion is coated with a coating and/or is textured. The coating may be tungsten, molybdenum, copper, or a refractory ceramic. The textured surfaces may include a surface roughness greater than 0.5 micron.
