Simpson Finish Trim Screw - #7 x 1-1/4" in Type 316 Stainless Steel with T10 6-Lobe Drive from Simpson Strong-Tie is a high-performance fastening solution engineered for clean, low-profile installations in both interior and exterior applications. Designed with a compact trim head that virtually disappears into the surface, this screw is purpose-built for trim work, molding, and finish carpentry where fastener visibility must be minimized. The Type 316 stainless steel construction delivers exceptional corrosion resistance, making it well-suited for outdoor environments, coastal conditions, and contact with preservative-treated wood.

Key Features

• Trim Head (0.200" head diameter) - low-profile cylinder head sits flush and nearly invisible after installation, delivering the clean, concealed appearance required for finish-quality work
• Patented SawTooth Point - eliminates the need for predrilling, saving time and reducing setup steps on trim, molding, and DIY home improvement projects
• Serrated Threads with Variable TPI - underhead serrated threads promote superior countersinking and increased pull-through resistance for a more secure, lasting hold
• T10 6-Lobe Drive - provides a secure, positive engagement between bit and fastener, reducing cam-out and extending bit life during repetitive driving
• Type 316 Stainless Steel Material and Finish - resists rust, salt spray, and chemical exposure, making this screw a reliable choice for exterior trim, wet environments, and preservative-treated lumber
• 0.75" Thread Length - optimized thread engagement for the 1-1/4" length ensures a firm grip without over-penetrating thinner substrates
• Suitable for Interior and Exterior Use - one versatile fastener handles a wide range of applications, from indoor millwork to outdoor trim installation in demanding conditions

Why This Product

• The SawTooth point technology means you can drive directly into wood without predrilling, cutting installation time significantly on trim and molding projects where dozens or hundreds of fasteners are needed.
• Type 316 stainless steel goes beyond standard corrosion resistance - it is specifically formulated to hold up against saltwater, harsh chemicals, and the preservatives found in treated lumber, making it the right choice when longevity in tough outdoor conditions matters.
• The trim head profile keeps fasteners visually minimal on finished surfaces - ideal when aesthetics are as important as holding strength in finish carpentry, cabinetry trim, or decorative molding applications.
• The T10 6-lobe driver bit is included, so you have everything needed to get started immediately without sourcing additional tooling - a practical convenience for both professional installers and DIY home improvement projects.

Frequently Asked Questions

Do I need to predrill before driving these trim screws?

No. The patented SawTooth point on this screw is specifically designed to eliminate the need for predrilling. It starts fast and drives easily into wood, reducing steps and speeding up installation on trim, molding, and other finish applications.

Are these screws suitable for use with preservative-treated wood outdoors?

Yes. This screw is made from Type 316 stainless steel, which provides strong resistance to corrosion from moisture, chemicals, and the preservatives used in treated lumber. It is rated suitable for both interior and exterior use, including applications involving preservative-treated wood.

What driver bit do I need for these screws?

These screws use a T10 6-lobe drive. A T10 6-lobe driver bit is included with #7 size screws, so you have the correct bit ready to use right out of the pack.

What makes the trim head design beneficial for finish applications?

The trim head has a compact, low-profile cylinder shape with a 0.200" head diameter, which allows it to countersink cleanly and sit nearly flush with the surface. This minimizes fastener visibility and provides the clean, concealed appearance required for professional-quality trim and molding work.
