Titan part 761-178 is a hexagonal flange screw designed for securing critical components on a wide range of Titan sprayers, including RentSpray, ProMark II, PowrTex, PowrLiner, Powerformer, Elite, Advantage, and Airless Sprayer models. The integrated flange distributes clamping force evenly, reducing the need for a separate washer and providing excellent vibration resistance. Replacing a stripped, lost, or damaged screw restores original clamping force and prevents loosening or misalignment during operation.

The Titan 761-178 Hexagonal Flange Screw is an OEM fastener used to secure pump housings, control panels, motor mounts, and other critical assemblies across dozens of Titan sprayer models. The hexagonal head provides positive engagement with standard tools, while the integrated flange eliminates the need for a separate washer and distributes clamping load evenly.
Over time, screws can become stripped, corroded, or lost during maintenance. Using an incorrect or worn fastener can lead to loosening, misalignment, or even component damage. Replacing with genuine Titan part 761-178 ensures correct thread engagement, proper clamping force, and long‑term reliability in high‑vibration sprayer applications.

When replacing a flange screw, it is often advisable to inspect or replace associated hardware to ensure a secure and lasting repair.
Inspect the nut for stripped threads or corrosion; replace if the screw does not thread smoothly.
For high‑vibration areas (engine mounts, pump housings), apply medium‑strength threadlocker to the new screw.
Check the mounting surface for damage, cracks, or deformation that could affect clamp load.
