Simpson 10d x 3" Gray Painted Siding Nail in Type 304 Stainless Steel is a premium fastener engineered specifically for attaching cedar, redwood, and cypress wood siding. Crafted from Type 304 stainless steel with a gray painted finish, this nail is designed to resist corrosion while keeping fastener heads visually discreet against siding surfaces. The checkered head pattern mimics natural wood texture so nail heads blend cleanly into finished siding installations, delivering both structural performance and a polished appearance.

Key Features

• Type 304 Stainless Steel material - provides lasting corrosion resistance, making this nail well suited for cedar, redwood, and cypress siding that is exposed to moisture and outdoor conditions
• Gray painted finish - helps nail heads blend with siding material so fasteners remain visually unobtrusive after installation
• Checkered full round head pattern - mimics wood grain texture so the head integrates naturally with wood siding surfaces rather than standing out
• Annular-ring shank - increases withdrawal resistance compared to smooth-shank nails, creating a more secure and lasting attachment that resists pull-through over time
• 12-gauge slender shank at 0.113 in. diameter - reduces splitting risk in delicate siding materials like cedar and redwood during driving
• Diamond point tip - enables easier, cleaner driving into siding material, reducing the chance of splitting or deflection
• 10d penny size at 3 in. length - sized appropriately for fastening wood siding panels with sufficient penetration depth for a secure hold
• 7/32 in. head diameter - compact head size limits visible surface area for a cleaner finished look on installed siding
• Made in the United States - domestic manufacturing supports consistent quality control and material standards

Why This Product

• For wood siding applications on cedar, redwood, or cypress, this nail addresses the common challenge of visible fastener heads - the gray painted finish and checkered head pattern work together to make nails blend into the siding surface rather than drawing the eye
• The annular-ring shank design resists withdrawal forces that occur as wood siding expands and contracts seasonally, reducing the risk of loose or popped nails over time
• Type 304 stainless steel construction delivers corrosion resistance appropriate for outdoor siding environments where moisture exposure is a regular factor
• The combination of a slender 12-gauge shank and a diamond point makes driving into sensitive species like cedar and redwood cleaner and less likely to cause splitting compared to heavier-gauge alternatives

Frequently Asked Questions

What type of siding materials is this nail designed for?

This painted siding nail is designed for cedar, redwood, and cypress siding materials. The slender 12-gauge shank and diamond point reduce the risk of splitting these wood species during driving.

Why does this nail have a checkered head pattern and gray painted finish?

The checkered pattern on the full round head is designed to blend with wood grain texture, and the gray painted finish helps the nail head visually match siding material - both features work together to keep fastener heads less noticeable on finished siding installations.

What is the benefit of an annular-ring shank on a siding nail?

The annular-ring shank increases withdrawal resistance compared to a smooth shank. This means the nail holds more securely in the siding material and is less likely to back out or pop loose as the wood naturally expands and contracts with seasonal moisture and temperature changes.

Is Type 304 stainless steel appropriate for outdoor siding projects?

Type 304 stainless steel provides corrosion resistance that is suitable for cedar, redwood, and cypress siding applications exposed to outdoor moisture. For seaside or coastal environments with elevated salt exposure, a Type 316 stainless steel option may be worth considering for superior corrosion resistance.
