The Titan 9800319 Hexagon Socket Screw is an OEM‑grade fastener engineered to securely assemble the pump, drive train, and frame components on Titan Hydrax and SprayTech airless sprayers. Made from hardened alloy steel with a protective finish, this socket‑head screw provides the clamping force needed to keep critical assemblies tight even under intense vibration and high pressure. Replacing a lost, corroded, or rounded‑out screw with the 9800319 eliminates movement that can lead to fluid leaks, unusual noise, and premature wear.
| Secure components | Threads into housings or brackets to lock the pump, motor, or frame parts together |
|---|---|
| Prevents shifting | Maintains precise alignment of mating surfaces under high mechanical loads and vibration |
| Distributes load | Hex socket head allows high tightening torque without rounding, ensuring a durable, long‑lasting joint |
| Stripped socket | Hex key spins without turning the screw, or tool slips under torque |
|---|---|
| Corrosion | Rust or paint has seized the threads, preventing proper removal or retightening |
| Missing screw | A visible gap or loose component where the screw should be |
| Vibration / rattling | Sprayer produces excessive noise or feels loose, traced to a backed‑out fastener |

|---|---|
| Product overview | The Titan 9800319 Hexagon Socket Screw is a precision‑manufactured fastener used to lock together the major structural and mechanical assemblies of Titan Hydrax and SprayTech airless sprayers. Whether it holds the pump to the frame, the motor to the housing, or the gearbox cover in place, this screw is built to withstand constant vibration and the stresses of high‑pressure pumping. A single loose or missing screw can set off a chain reaction: parts start to move, seals begin to leak, and expensive components wear prematurely. Replacing worn screws with the 9800319 keeps your sprayer tight, safe, and productive. |
| Function | This hexagon socket screw provides a high‑clamping‑force joint that resists vibration and shock loads. The internal hex drive allows a hex key or bit to apply substantial torque without damaging the screw head, making installation and removal reliable even after years of service. Once torqued, it keeps mating surfaces in firm contact, preventing gaps that could allow paint or air leakage. |
| Industrial Applications | The sprayers that use this screw are deployed in a variety of demanding environments: residential and commercial painting, heavy‑duty industrial coating, facility maintenance, shipyard and marine work, bridge and infrastructure projects, and fine finishing. In all these settings, loose fasteners are a safety and performance liability that the 9800319 screw helps eliminate. |
| Compatible Equipment | Confirmed fitments include: Hydrax 4540-7230, SprayTech CS5100, CS8100, CS9100, CS9900, and CS9960. Always cross‑reference your machine’s parts list to identify the exact placement and number of screws required for your specific repair. |
| Compatible Parts & Assemblies | This screw is used alongside the main pump housing, motor mounts, gearbox covers, frame brackets, and sometimes the control panel housing. It often shares a mounting location with other identical screws, so purchasing a full set is advisable during a teardown. |
| Related Parts Commonly Serviced Together | When the 9800319 is replaced, technicians often check the pump packings, O‑rings, gaskets, and any shims or washers that sit beneath the screw head. If a screw was missing, nearby fasteners may have been overtightened in compensation, so inspect them all. |
| Common Problems Solved | A compromised screw can cause the pump to shift, leading to misalignment with the drive shaft, premature seal wear, fluid leaks, increased vibration, and unusual noise. Replacing it restores the rigid assembly needed for smooth, high‑pressure spraying. |
| Use with Coating Systems | The screw’s function is independent of the coating material. It performs equally well whether the sprayer is running latex, epoxy, lacquer, or heavy protective coatings. The screw’s plating resists corrosion from solvents and waterborne paints. |
| OEM & Brand Information | Titan is a trusted manufacturer of professional spray equipment, and the 9800319 Hexagon Socket Screw is an OEM‑exact part. Using genuine Titan fasteners ensures correct tensile strength, thread pitch, and head profile—critical factors in maintaining joint integrity. Substitutes may fail under load or cause damage to threaded bosses. |
| Commercial Benefits | For any painting contractor or maintenance department, having spare 9800319 screws on hand means a quick fix is always available. Avoid the downtime and lost revenue that comes from a simple missing screw holding up a job. For rental companies, consistent use of OEM fasteners reduces equipment breakdowns and extends service intervals. |
| Detailed Technical & Commercial Overview | Fasteners are often overlooked during routine maintenance, but they are the literal backbone of any spray system. The Titan 9800319 Hexagon Socket Screw is made to handle the repetitive stress and chemical exposure found in airless painting. Its socket head design allows for confident, repeatable torque application with common hex keys, and the hardened material resists rounding out even after multiple service cycles. When a pump or motor is removed for service, re‑using the old screws is a gamble. The original threads may have stretched, or the socket may be slightly worn, leading to a lower clamping force on reassembly. A fresh screw guarantees full torque and a secure joint. This is especially important in high‑pressure pumps where any movement between parts can quickly ruin an expensive seal or bearing. From a commercial standpoint, a few dollars invested in the correct OEM screw can prevent hundreds of dollars in collateral damage. A loose pump housing can score a piston rod, ruin packings, and require a full rebuild. The 9800319 is insurance against that scenario—a small part that makes a big difference in sprayer reliability and total cost of ownership. |
When replacing the 9800319 screw, these companion items are often inspected or replaced to ensure a leak‑free, properly torqued assembly.
If a loose screw caused pump movement, packings may be scored or flattened. A fresh packing kit restores pressure and stops leaks.
Replace any O‑rings and gaskets that were disturbed when the screw was removed to ensure a perfect seal.
Consider replacing all similar screws at once to maintain uniform clamping force and avoid future failures.
