Product Description
The Simpson #7 1-5/8 in. Self-Drilling Siding Screw in Type 410 Stainless Steel is purpose-built for attaching wood siding, wood panels, and metal trim to steel studs without the need for pre-drilling.

The 100-count pack makes it a practical supply for professional contractors and serious DIYers tackling siding and trim work.
Key Features
- Type 410 Stainless Steel Construction - Can be hardened through heat treatment, giving this screw the strength needed to self-drill through metal studs while holding up in demanding job-site conditions.
- #3 Drill Point - Self-drilling tip eliminates the need for pre-drilling into steel studs, saving time and reducing the number of tools required on the job.
- Low-Profile Trim Head - Minimizes surface disruption for a clean, finished appearance on siding and trim applications where aesthetics matter.
- #1 Square Drive - Provides positive bit engagement and reduces cam-out during installation, giving the installer greater control and a cleaner drive.
- Full Thread Length - Threading that runs the entire shank length maximizes pull-through resistance and grip across the full fastened assembly.
- 19 TPI Thread Pattern - Fine thread pitch suited for fastening into steel stud framing, ensuring consistent thread engagement and holding power.
Why This Product
- No Pre-Drilling Required - The #3 self-drilling point bores directly into steel studs, streamlining installation for wood siding, wood panels, and metal trim without an extra step or additional tooling.
- Built for Metal Framing Applications - Specifically engineered by Simpson for attaching siding and trim components to steel stud framing, making it a targeted solution rather than a general-purpose fastener.
- Clean Finish Where It Counts - The low-profile trim head sits flush and discreet against finished surfaces, making these screws well suited for visible trim and siding work where appearance is part of the result.
- Reliable Drive Performance - The #1 square drive reduces the slipping and cam-out common with other drive styles, helping installers work faster and with less risk of marring the surrounding surface.

Frequently Asked Questions
- Do these screws require pre-drilling before installation?

- These screws are engineered for attaching wood siding, wood panels, and metal trim to steel studs, making them well suited for construction and finishing applications.
- Is Type 410 stainless steel as corrosion resistant as other stainless steel grades?
- Type 410 stainless steel can be hardened through heat treatment, which gives it the ability to drill through metal. However, it does not offer the same level of corrosion resistance as Type 316 or Type 305 stainless steel, so it is important to consider the exposure conditions of your application before use.
