Abstract
A fastener and a method for reducing wear on a driver blade in a fastening tool includes applying a layer of solid-based lubricant between the head of a fastener and a driver blade end. The fastener is for use in a fastening tool and includes a head, a shank, and a layer of lubricant on the head of the fastener. The lubricant is graphite, molybdenum disulfide, tungsten disulfide, boron nitride, polytetrafluoroethylene (PTFE), nano-diamonds, calcium stearate, sodium stearate, oils, greases, waxes, thermoplastic polymers, or another lubricant that exhibits similar characteristics. Aromatic polyamides (such as Kevlar™), ultra-high molecular weight polyethylene, powdered glass, glass fibers, thermoplastic polymers, and thermoset polymers also are contemplate to provide a barrier to contact between the driver blade and fastener head. The lubricant is sprayed, rolled, brushed, blotted or otherwise applied between the head of the fastener and the driver blade end prior to firing the fastening tool.
