Juggling two screw diameters across a roofing, HVAC, or framing job means constantly stopping to find the right size. This 425-piece assortment eliminates that problem by combining both #8 and #10 Phillips wafer head self-tapping screws — across five lengths each — in one organized black oxide kit.
Every screw is machined from 410 stainless steel with a black oxide coating for corrosion resistance and a clean, low-profile finish. The wafer head sits flush against thin materials, and the Phillips drive works with any standard power drill. Sizes span #8 × 1/2" through #10 × 1-1/2", covering the most common light-gauge sheet metal, roofing, and panel fastening tasks. Total kit weight is not specified — contact us to confirm if needed.
From metal roofing and HVAC ductwork to steel keel framing, gutter pipe, iron fencing, and hurricane panels, these black self-tapping screws deliver a fast, corrosion-resistant hold in demanding indoor and outdoor environments.

Secure metal roofing panels, flashing, and hurricane panels with a flush-sitting wafer head that won’t snag or lift under wind load — black finish blends with dark panel colors.
Keep both #8 and #10 diameters on hand for duct assembly, steel keel framing, and gutter pipe fastening — no need to carry two separate kits to the job site.
Attach iron fencing, metal trim, and sheet metal panels with corrosion-resistant 410 stainless steel fasteners that hold up to outdoor exposure without rusting or loosening.

No. The self-tapping sharp point cuts its own thread directly into wood, sheet metal, and other hard materials without a pre-drilled pilot hole, saving time and reducing the number of tools needed on site.
#8 and #10 refer to the screw diameter — #10 is slightly larger in diameter than #8. #8 screws are typically used for lighter-gauge materials and tighter spaces, while #10 screws provide a stronger hold in thicker or denser substrates. This kit includes both so you can choose the right diameter for each application.
Yes. The 410 stainless steel base with black oxide coating provides good corrosion and rust resistance, making these screws suitable for outdoor applications including roofing, HVAC, fencing, and hurricane panels. For highly corrosive marine or coastal environments, 316 stainless steel is generally recommended for long-term exposure.
A standard Phillips #2 bit fits these screws. A power drill or cordless screwdriver set to moderate torque is recommended for sheet metal and roofing applications to avoid stripping the head.
The 410 stainless steel base provides the primary corrosion resistance. The black oxide coating adds surface protection and aesthetic finish. In most outdoor environments, the combination performs well. For prolonged exposure to salt air or highly corrosive conditions, contact us to confirm suitability for your specific application.
Yes. These screws are noted for use with hurricane panels. The wafer head provides a flush, low-profile hold that resists pull-through, and the 410 stainless steel construction offers the corrosion resistance needed for outdoor storm protection applications. Always verify local building code requirements for hurricane panel fastener specifications.
The 425 screws are sorted by size and diameter into compartments within a durable storage box. Each compartment holds a specific size so you can identify and retrieve the correct screw quickly without sorting through loose fasteners.
