Product Description
The Simpson Trim-Head Screw #7 x 1-5/8 in. 316 Stainless Tan 01 is a precision decking fastener built from Type 316 Stainless Steel for superior corrosion resistance in marine and high-exposure environments where PVC or composite decks are installed. Its low-profile trim-style head delivers a clean, finished appearance on the decking surface, and the Tan 01 painted head is matched to blend with most major PVC and composite decking manufacturers - one of 13 available colors. Each 70-piece pack includes a T15 driver bit so the job can start immediately.
Key Features
- Type 316 Stainless Steel construction - provides superior corrosion resistance in salt air, moisture, and other harsh conditions common to docks, boardwalks, and coastal deck installations where standard fasteners fail prematurely.
- Trim-style head with 0.230 in. diameter - the low-profile head sits discreetly on the decking surface, resulting in a cleaner, more professional finished appearance than standard screw heads.
- Tan 01 painted head, matched to major decking brands - one of 13 color options engineered to blend with most major PVC and composite decking manufacturers, keeping fasteners visually inconspicuous.
- Type-17 point - designed for fast starts, reducing setup time and allowing the screw to self-start without excessive force on the work surface.
- Coarse threads on approximately 2/3 of the shank - draws the decking and other material tightly to the framing for a firm, secure connection with every installation.
- T15 6-lobe drive - helps prevent driver-bit cam-out during driving, resulting in easier installation, less operator fatigue, and longer driver bit life.
- T15 driver bit included - the pack ships ready to use, with a replacement bit available separately for continued use on larger projects.
- Predrilling recommended near board ends - a simple precaution that helps prevent splitting when fastening close to the edges of decking boards, protecting the material investment.
Why This Product
- Purpose-built for demanding outdoor environments - Type 316 Stainless Steel is specified precisely because it outperforms standard stainless grades against the moisture, salt air, and chemical exposure found in marine settings and high-exposure deck applications such as docks and boardwalks.
- A cleaner deck surface without the hardware showing - the trim-style head and color-matched Tan 01 finish work together so fasteners blend into the decking rather than drawing the eye, a meaningful upgrade over standard-head screws on visible outdoor surfaces.
- Engineered details that speed up installation - the Type-17 point for fast starts, the 6-lobe drive that resists cam-out, and the included T15 bit combine to reduce the friction points that slow down a decking project on the job site.
- Versatile fit across common decking applications - compatible with wood decking, select composite decking materials, PVC deck boards, docks, and boardwalks, making this a single fastener solution across multiple project types without switching products.

Frequently Asked Questions
- What type of decking materials are these screws compatible with?
- These trim-head screws are designed to fasten wood decking and some composite decking materials. They are particularly well-suited for PVC and composite deck installations in marine or high-exposure environments where superior corrosion resistance is required, such as docks and boardwalks.
- Why is Type 316 Stainless Steel specified for these screws?
- Type 316 Stainless Steel provides superior corrosion resistance compared to standard stainless grades, making these screws ideal for marine environments and other high-exposure applications where moisture, salt air, or harsh conditions could cause standard fasteners to corrode prematurely.
- Is predrilling required before installing these screws?
- Predrilling is not required in most applications, as the Type-17 point is designed for fast starts. However, predrilling is recommended near board ends to prevent splitting. The coarse threads on approximately 2/3 of the shank draw the decking material tightly to the framing for a secure hold once driven.
- What drive bit is needed, and is one included with this package?
- These screws use a T15 6-lobe drive, which helps prevent driver-bit cam-out for easier driving and longer bit life. Each 70-piece pack includes one T15 driver bit. If a replacement bit is needed, the compatible replacement model is BIT15T-2-R2.
