    • 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.
    • 用于减少紧固工具中的驱动器叶片上的磨损的紧固件和方法包括在紧固件的头部和驱动器刀片端部之间施加一层固体润滑剂。 紧固件用于紧固工具,并且在紧固件的头部上包括头部,柄部和润滑剂层。 润滑剂是石墨,二硫化钼,二硫化钨,氮化硼,聚四氟乙烯(PTFE),纳米金刚石,硬脂酸钙,硬脂酸钠,油,油脂,蜡,热塑性聚合物或具有相似特性的其他润滑剂。 芳族聚酰胺(例如Kevlar TM),超高分子量聚乙烯,玻璃粉末,玻璃纤维,热塑性聚合物和热固性聚合物也被设想为驱动器叶片和紧固件头之间的接触提供屏障。 在点燃紧固工具之前,润滑剂被喷涂,滚动,拉丝,印迹或以其它方式施加在紧固件的头部和驱动器刀片端部之间。
