Titan 862-438 Thumb Screw for PowrLiner, PowrTex and PowrTwin Sprayers
Titan 862-438 is an OEM thumb screw engineered for tool-free hand tightening and loosening on compatible Titan spray equipment. This specialized fastener features a knurled or winged head that allows operators to secure access panels, covers, and quick-release components without reaching for a wrench or screwdriver. The 862-438 is verified as an official Titan part used across an extensive range of PowrLiner, PowrTex, and PowrTwin models, including the PowrLiner 4000 through 8955 series, PowrTex 6900SF and 12000SV texture sprayers, and the PowrTwin 3500 through 12000 lineup. Thumb screws are subject to wear from repeated use, exposure to coatings and solvents, and the vibration inherent in sprayer operation. Over time, threads can strip, the knurled grip can wear smooth, or corrosion can weaken the fastener, making hand tightening difficult or impossible. A missing or damaged thumb screw can leave panels loose, compromise component security, and slow down routine maintenance. The 862-438 is manufactured to original specifications for proper thread engagement and clamping force. Always verify fitment against your specific model's parts diagram before ordering.
