Titan 862-501 Thread Cutting Screw

Part number 862-501 is a Thread cutting Screw, a specialized self-tapping fastener engineered for use across an extensive range of PowrTwin and PowrLiner sprayer systems. Unlike standard machine screws that require pre-tapped holes, this thread cutting screw is designed to form or cut mating threads into the base material during installation. This unique characteristic makes it ideal for use in plastic housings, sheet metal components, and situations where field service requires reliable thread formation without specialized tapping operations.

This fastener is utilized in multiple critical applications throughout compatible equipment. On PowrTwin 12000 Plus DI, 6900, 8900, and 4900 series plural component sprayers, it secures control panel covers, access doors, and housing components. On PowrLiner 6950_1, 6950, 4950, and the 4955, 6955, 8955 series airless sprayers, this screw is used for attaching nameplates, mounting brackets, and protective shrouds. The thread cutting design provides excellent pull-out resistance and vibration resistance in the parent material while allowing for disassembly and reassembly when properly installed.

Thread cutting screws are manufactured to precise specifications including thread geometry, hardness, and point style to ensure consistent cutting action without damaging the base material. Failure modes for these specialized fasteners include stripped drive recesses from repeated service, worn or dull cutting threads that no longer form proper mating threads, corrosion that compromises structural integrity, and loss of material in the parent component from multiple installation cycles. A damaged or missing thread cutting screw can result in loose panels, increased vibration, component misalignment, and potential ingress of contamination into sensitive areas.
