Black Steel Splash Shield Retainer Screw, M4.2 x 25 mm for 2003-2021 Buick, Chevrolet and Saturn Vehicles
Dorman 700-044 splash shield retainers replace missing or damaged screws that hold factory splash shields and related vehicle components in place on validated Buick, Chevrolet, and Saturn applications. The black steel, self-drilling screw design uses a captive washer to help clamp the shield securely, making it a practical service fastener for repairing loose underbody panels without guessing at hardware size.
Dorman 700-044 Technical Specifications:
- Black steel screw construction is suited for splash shield service where road splash, vibration, and repeated panel removal can expose weak or mismatched hardware.
- M4.2 x 25 mm sizing, 29 mm overall length, 9 mm head diameter, and 7 mm head size provide concrete measurements for matching the original fastener location.
- A 4 mm metric thread diameter with 0.41 thread pitch supports use as a sheet metal and self-drilling screw in applicable automotive fastening points.
- Captive washer design helps spread clamping force across the splash shield mounting point when replacing lost or damaged factory hardware.
Commonly used when a factory splash shield screw is missing, stripped, corroded, or damaged during underbody service.
Catalog fitment covers applications such as Buick Cascada, Regal Sportback, and Regal TourX; Chevrolet Cruze and Trailblazer; and Saturn Aura and Ion. Verify the fastener size and mounting location against the vehicle before installation.
