Which vehicles and model years will these Rexka grommets fit?

The Rexka assemblies are sized and specified to match the original grommets used on a range of Ford and Lincoln models. Compatibility covers popular full-size trucks, vans and SUVs from the mid-1990s through the mid-2000s where the factory used the same cowl fastener part numbers.

How do these grommet and screw assemblies replace the original parts?

Each assembly combines a white nylon grommet with an M4.2 (#8) adjusting screw sized for a 10mm x 14mm hole, replicating the factory fastener’s form and function. Installation requires removing the damaged grommet or screw and pressing the replacement into the factory hole; the adjusting screw secures the cowl vent to the body.

• Screw size: M4.2 (#8) for direct thread compatibility
• Grommet installs into a 10mm x 14mm hole
• Simple press-fit grommet; screw tightens to seat the vent
• Sold in a set of 15 for multiple replacements or full-panel repair

What materials and specifications should I expect from Rexka replacements?

When should I replace my cowl vent grommets and screws?

Replace these fasteners if you notice loose or missing cowl vents, cracked grommets, or screws that no longer tighten securely. Damaged cowl fasteners can allow vibration, water ingress or misalignment of the vent assembly, so refreshing the mounting hardware restores proper fit and reduces noise.

• Replace when grommets are cracked, brittle, or missing
• Install new screws if threads are stripped or corroded
• Use a full set when multiple fasteners show wear for consistent fit
• Ideal during cowl or windshield service to prevent future issues
