Simpson Trim-Head Decking Screws in #7 x 2-1/4" with a T15 6-Lobe Drive are engineered for clean, professional installations on PVC and composite decking in marine and high-exposure outdoor environments. Finished in Type 316 Stainless Steel with a painted Brown 01 head, these fasteners deliver superior corrosion resistance while blending seamlessly into the deck surface - making them a go-to choice for coastal projects, poolside structures, and any application where long-term durability and a polished appearance matter most.

Key Features

• Trim Head design with 0.230" head diameter - sits low and discreet on the decking surface for a clean, finished look that lets the decking material take center stage rather than the fastener
• Type 316 Stainless Steel material and finish - provides superior corrosion resistance in saltwater, marine, and high-humidity environments where standard fasteners would fail prematurely
• Brown 01 painted head - color-matched to blend with major PVC and composite decking manufacturers, reducing the visibility of fasteners for a professional, cohesive appearance
• T15 6-Lobe drive - resists cam-out during installation, resulting in easier, more controlled driving and extended driver bit life on the job
• Type-17 point - enables fast, accurate starts without pre-drilling through most of the deck board, speeding up installation and reducing fatigue
• Coarse thread pattern - draws decking boards tightly to the framing for a secure, tight connection that minimizes gaps and board movement over time
• Approximately 138 screws per pound - makes it straightforward to estimate the quantity needed for your project and manage material costs accurately

Why This Product

• Built for coastal and marine environments - Type 316 Stainless Steel is the recommended choice for seaside and high-exposure applications where chlorides and moisture accelerate corrosion in lesser materials, helping your deck installation hold up for years without rust bleed or structural compromise.
• Designed specifically for PVC and composite decking - the trim-style head and Brown 01 color-matched finish work together to produce a nearly invisible fastener profile that meets the aesthetic expectations of premium composite deck installations.
• Faster, cleaner installation with less rework - the combination of a Type-17 point for quick starts, coarse threads that pull boards tight, and a 6-Lobe drive that prevents cam-out means fewer stripped fasteners, less frustration, and a more consistent finished product.
• Versatile color matching for major decking brands - with painted heads available in 13 colors (of which Brown 01 is one), these screws are engineered to complement most leading PVC and composite decking product lines, giving installers a single fastener system that works across a wide range of projects.

Frequently Asked Questions

Why should I choose Type 316 Stainless Steel over other finishes for my deck project?

Type 316 Stainless Steel provides superior corrosion resistance compared to standard stainless grades, making it the recommended choice for marine environments, seaside installations, and any high-exposure outdoor setting where moisture and salt are present. It helps prevent rust bleed that can stain and damage composite or PVC decking surfaces over time.

Will these screws work with my composite or PVC decking brand?

These Trim-Head screws are designed to blend with most major PVC and composite decking manufacturers. The Brown 01 painted head is one of 13 available colors engineered specifically to match popular decking product lines, so the fasteners remain as inconspicuous as possible on the finished deck surface.

Do I need to pre-drill before installing these screws?

The Type-17 point is designed for fast starts and helps drive into decking material without requiring pre-drilling in most cases. However, pre-drilling is recommended near board ends to prevent splitting - particularly important when working close to the edges of PVC or composite boards.

What does the 6-Lobe T15 drive offer compared to a standard Phillips drive?

The T15 6-Lobe drive transfers torque more evenly across six contact points rather than four, which significantly reduces cam-out - the tendency for the driver bit to slip out of the screw head under load. This results in easier driving, less damage to the screw head, and a longer useful life for your driver bits, all of which add up to a faster and cleaner installation.
