The Husqvarna 542020489 Hwhsts Screw.25-20 X.75 Type F is a genuine OEM fastener designed for the MS510, TS250X, TS250XL, and MS510G tile and masonry saws. As a direct OEM component, this screw is manufactured to Husqvarna's exact thread specification and dimensional tolerances, ensuring a secure, rattle-free connection in the assembly it anchors. DHS Equipment supplies this part to help keep your tile and masonry saw operating correctly. Cross-reference part number 542020489 against your machine's parts diagram to confirm the correct installation point before ordering.
Key Features
- Correct Thread Form and Length — A .25-20 UNC thread at .75 inches with a Type F cutting-thread profile means this screw taps cleanly into the receiving material without pre-drilling, locking the assembly securely in place.
- Genuine OEM Specification — Sourced directly from Husqvarna, this fastener meets the exact material grade and dimensional standard specified for the original build — no guesswork on thread class or head type.
- Broad Tile and Masonry Saw Fitment — Confirmed for the MS510, MS510G, TS250X, and TS250XL tile and masonry saws, covering multiple variants within Husqvarna's TS and MS saw families.
- Structural Integrity Restored — A loose or damaged fastener in this position can allow guards, covers, or structural panels to shift during operation. Installing the correct replacement restores the rigidity the saw depends on.
- Drop-In Replacement — This screw installs directly in place of the original, requiring no thread chasing or rework when the mating hole is in good condition.
A Type F thread-cutting screw like this one is designed to form or cut its own mating thread as it is driven into the receiving material, creating a tight, vibration-resistant fastening point without a separate nut. In a tile or masonry saw environment — where water, slurry, and continuous vibration are constant — fasteners that lose grip can allow panels, guards, or component mounts to work loose, compromising both cut accuracy and operator safety. Replacing a stripped or missing screw with the correct OEM part restores the assembly to its intended clamping force and keeps every attached component properly secured during cutting operations.
