Simpson Finish Trim Screw, #9 x 5", Tan, T15 6-Lobe Drive from Simpson Strong-Tie is a high-performance fastening solution engineered for clean, professional results on trim, molding, and a broad range of interior and exterior finishing work. Its low-profile trim head sits flush and nearly invisible against finished surfaces, while the patented SawTooth point technology drives fast without predrilling - saving time and reducing splitting risk. Protected by Quik Guard Coating and available in a tan finish to blend with common trim colors, this screw is built for both indoor applications and exterior use, including installation into preservative-treated wood.

Key Features

• Trim Head Design (0.230 in. diameter): the compact, low-profile cylinder head minimizes fastener visibility for a clean, concealed appearance on finished trim and molding surfaces
• Patented SawTooth Point: eliminates the need for predrilling, allowing for fast starts and easy driving even in dense or preservative-treated wood - reducing labor time significantly
• Serrated Thread Pattern: underhead serrated threads improve countersinking performance and increase pull-through resistance, helping the fastener hold securely in place over time
• T15 6-Lobe Drive: the 6-lobe recess provides secure bit engagement, reducing cam-out and extending driver bit life for more efficient installation
• Quik Guard Coating in Tan: the protective coating and tan color work together to resist corrosion and blend naturally with common trim finishes, making this screw suitable for both interior and exterior applications
• 5" Length with 2.00" Thread Length: the extended overall length combined with a precisely defined thread engagement zone gives installers strong, consistent holding power in deeper assemblies

Why This Product

• For trim and molding installation where appearance matters, the low-profile trim head and tan color minimize the need for touch-up filler or concealment work - the fastener blends in from the start
• The SawTooth point removes the predrilling step entirely, making this screw a practical time-saver for DIY home improvement projects and professional finish carpentry alike
• Rated for both interior and exterior use, including preservative-treated wood, this is a single versatile fastener that works across a wide range of project conditions without needing a specialty alternative
• The 6-lobe T15 drive reduces bit slipping and cam-out during installation, delivering more control and a cleaner finish - especially useful when driving into trim where surface damage is hard to hide

Frequently Asked Questions

Does this screw require predrilling before installation?

No. The patented SawTooth point is specifically designed to eliminate the need for predrilling. It enables fast starts and easy driving, including into preservative-treated wood, reducing prep time and the risk of splitting material near the edge of trim or molding.

Is this screw suitable for exterior use or contact with treated lumber?

Yes. The Finish Trim screw with Quik Guard Coating is suitable for both interior and exterior applications, and it is compatible with preservative-treated wood - making it a versatile choice for a wide range of residential finishing projects.

What drive bit does this screw require?

This #9 size Finish Trim screw uses a T15 6-lobe drive. A T15 6-lobe driver bit is included with #9 size packs. If you need a replacement, the compatible replacement driver bit is BIT15T-2-R2.

Why is a trim head preferred over a standard screw head for finish applications?

The trim head on this screw measures 0.230 in. in diameter, which is significantly smaller and lower-profile than a standard screw head. This compact head countersinks cleanly into the material surface with minimal visible fastener profile, which is especially important in finish carpentry where a clean, concealed appearance is the goal.
