GRK 117760 #9 x 4 FIN Trim Head Screws 50 Count - Clean Trim Finish

Our review of the GRK 117760 #9 x 4 FIN/TrimTM screws finds them best suited for carpenters and serious DIYers who need a neat finish and reliable fastening for interior or exterior trim work. The single biggest reason to buy is the combination of a low-profile trim head and a star drive that resists cam-out, which produces a clean, professional appearance while saving time on installation. These screws are noted by users for penetrating dense woods and resisting splitting, making them a practical choice for cabinetry, molding, and fine carpentry projects.

Key Features

• Trim Head: The low-profile finishing trim head creates a clean completed look that sits discreetly beneath paint or filler on casings and moldings.
• Star Drive: The star drive reduces stripping and cam-out, improving productivity and making long installation runs less frustrating.
• Versatile Use: Rated for interior and exterior use, these screws perform reliably on both indoor cabinetry and outdoor trim where corrosion resistance is required.
• Length and Size: The 4 in length and #9 gauge make them long and strong enough to secure thick trim and penetrate dense hardwoods without needing pilot holes in many cases.
• Strength: Customers report the screws hold well without splitting wood, giving confidence when working with delicate or expensive materials like oak.

Who It's For

This product is aimed at finish carpenters, cabinet installers, and experienced DIYers who value a neat, low-profile fastening and the reliability of a star drive. If you frequently install baseboards, crown molding, door casings, or cabinet face frames, these screws will save time and reduce visible repair work after installation.

Those working exclusively on very light materials or who require specialty fasteners (for example, structural lag bolts or micro screws for fine cabinetry) should look elsewhere. Also, if a countersink flush with a screw head is required for a specific decorative fastener, a different head style may be preferable.

Pros & Cons
