Verified fitment includes WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, WT5HPSG, STXDF, QP4TKT, and PRX series equipment. When you order by part number 9509, you can trust you're receiving the correct hardware straight from the Multiquip parts catalog.
Key Features
- Genuine OEM Hardware Grade — Meets Multiquip's specified thread form, point geometry, and drive type for self-tapping applications, so the screw cuts cleanly and holds securely in sheet metal and light structural panels.
- Drop-In Installation — The Tek 12 x 3/4 self-tapping design drills its own pilot hole on installation, eliminating the need for pre-drilling in compatible panel thicknesses.
- Broad Multiquip Fitment — A single part number covers Water Trailer (WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, WT5HPSG), STXDF ride-on trowels, QP4TKT trash pumps, and PRX power floats.
- Structural Holding Power — Self-tapping tek screws anchor panels, guards, and covers firmly in place; a loose or stripped fastener in these locations can allow covers to shift, vibrate free, or expose internal components.
- Access Panel and Guard Integrity — Properly torqued fasteners keep protective covers and access panels secured during operation, which is especially important on pumps and power trowels operating under sustained vibration loads.
A tek screw is a self-drilling, self-tapping fastener that combines a drill-point tip with hardened threads to cut through metal sheet without a pre-drilled pilot hole. On equipment like water trailers, power trowels, trash pumps, and ride-on power floats, these screws are used to fasten panels, guards, covers, and brackets to the machine frame. When a tek screw becomes stripped, corroded, or sheared, it can leave panels loose or unsecured, creating vibration noise, potential access to internal components, and accelerated wear on surrounding sheet metal. Replacing with the correct Multiquip 9509 restores a tight, secure fastening point using hardware built to the original specification.
