Titan 862-444 Screw
OEM Titan Sprayer Hardware
Titan 862-444 Screw is an OEM Grade 5 hex head cap screw (3/8-16 x 1-1/4) used to secure critical components including motor mounts, pump housings, and structural guards on compatible PowrTwin, PowrLiner, PowrCoat, PowrDrive, and Hydra X sprayer models.
Compatibility Overview
Grade 5 steel construction provides high tensile strength for demanding vibration and load conditions. Precise thread pitch and head dimensions ensure proper clamping force and reliable assembly. A stripped, corroded, or missing screw allows critical components to shift, causing misalignment, vibration, and potential safety hazards. OEM replacement restores original engineered integrity.

Titan 862-444 Screw for PowrTwin, PowrLiner & Hydra X Service
Titan 862-444 is a genuine OEM hex head cap screw designed for critical component retention across a wide range of professional Titan sprayer platforms. Listed as "Screw, hex head (2)" in the official Titan Hydra X service manual and as part of the Drive Assembly in the Titan 759-135 owner's manual, this fastener is specified as a 3/8-16 x 1-1/4 Grade 5 screw. While a screw may appear to be a simple component, this fastener is manufactured to precise engineering specifications including thread pitch, diameter, length, head style, drive type, and material grade. These specifications are carefully selected to provide the correct clamping force, vibration resistance, and long-term reliability required for each application. Common applications include securing motor mounts to frames, attaching control panels and covers, fastening pump housing components, and retaining structural guards and shrouds. The screw is manufactured from corrosion-resistant Grade 5 steel to withstand exposure to paints, solvents, moisture, and temperature extremes. Fasteners in these professional systems are subjected to continuous vibration from engines, motors, and pumps, thermal expansion and contraction, and chemical exposure. Failure modes include stripped drive recesses from repeated service, thread damage from over-torquing or cross-threading, corrosion, and stress fatigue. A damaged or missing screw can allow critical components to loosen, shift, or separate during operation, leading to misalignment, increased vibration, accelerated wear, and potential safety hazards. This genuine OEM replacement restores the equipment to its original engineered condition. Always use the exact factory-specified screw when replacing fasteners. Do not substitute hardware store fasteners, as differences in hardness, thread pitch, grade, or length can cause component damage or premature failure. Always verify compatibility against your specific sprayer's parts diagram, as fastener configurations vary across models and production revisions.

The 862-444 Screw is a critical fastener for compatible Titan sprayers. Always use the exact factory-specified screw when replacing fasteners. Do not substitute hardware store fasteners, as differences in hardness, thread pitch, grade, or length can cause component damage, inadequate clamping force, or premature failure. If the drive recess is stripped, threads are damaged, or the screw is missing, replace it immediately to prevent component loosening and potential safety hazards. Verify model compatibility against your Titan parts diagram, as fastener configurations vary across sprayer platforms.
