GRK 115734 #8 x 3-1/8in Fin/Trim Finish Head Screws 300 Count - Clean

In this review the GRK 115734 FIN/TRIM finish head screws are examined for trim carpentry and cabinetry projects; the bottom line is these screws are for anyone who needs a low-profile, reliable fastener that reduces visible heads while resisting stripping. The reviewer found them especially useful when a clean finished look matters, because the trim head is the smallest available and sits discreetly in wood. They also appreciated the star drive for its improved productivity and reduced cam-out, and noted the screws are suitable for both interior and exterior use when the application calls for a compact head and strong thread hold.

Key Features

• Trim Head: The very small head delivers a discreet finished appearance that minimizes the need for excessive filling or touch-up.
• W-Cut Thread Design: Threads are designed to reduce material splitting and to pull boards together tightly for secure joints.
• Star Drive: The star drive reduces stripping and improves bit engagement, which speeds installation and lowers tool wear.
• Length Range: Available in lengths suitable for common trim applications, allowing selection for thin molding or thicker trim pieces.
• Interior/Exterior Use: Engineered for versatile use around the home, on both indoor trim and exterior finish work when appropriate.

Who It's For

The GRK FIN/TRIM screws are best for finish carpenters, cabinetmakers, and skilled DIYers who prioritize a neat finished surface and reliable holding power. If you frequently install crown molding, door and window casings, or built-in cabinetry and want to avoid large visible screw heads, these are a practical choice.

Those working exclusively with extreme hardwoods such as Mahogany or Ip should be prepared to pre-drill in some cases; if you need rustproof fasteners for prolonged exterior exposure in coastal conditions, consider specialist exterior-rated coatings beyond the standard finish offered here.
