Simpson #10 x 1-7/16" Self-Drilling Wafer-Head Screw with Wings in Type 410 Stainless Steel is engineered for attaching plywood and OSB panels directly to steel studs, delivering a clean, reliable connection in light-gauge steel framing applications. The combination of a self-drilling point, break-off wings, and a ribbed wafer head makes this fastener a practical choice for contractors and builders who need a screw that drills, clears, and seats in a single operation - without pre-drilling or separate clearance steps.

Key Features

• #2 Phillips drive - fits the most common driver bits on the jobsite, reducing the need for specialty tooling and speeding up installation.
• Machine-screw thread, threaded full length - full-length threading maximizes thread engagement into the steel substrate, producing a stronger, more secure hold than partial-thread designs.
• Wings above the drill point - create a clearance hole in the wood or panel layer so the workpiece does not climb up the shank during installation; wings break off cleanly as the point engages the steel, keeping the connection tight and flush.
• #3 drill point (size 3) - sized to self-drill through steel substrates without a pilot hole, saving installation time and eliminating extra drilling steps.
• Type 410 stainless steel with additional corrosion protection coating - heat-treatable alloy that can be hardened to drill through metal, with a supplemental coating for improved resistance to moisture and mild corrosive environments beyond what bare 410 offers.
• Ribbed wafer head, 0.450" head diameter - low-profile head sits flush against panel surfaces while the ribs help resist rotation during drive, reducing cam-out and improving pull-through resistance in panel applications.
• 24 TPI machine threads - fine thread pitch provides smooth, controlled engagement into steel studs, minimizing wobble and maintaining alignment during fastening.

Why This Product

• Designed specifically for panel-to-steel-stud connections, this screw eliminates the need to pre-drill clearance holes in wood or OSB - the break-off wings handle that automatically, making the installation process faster and more consistent on framing projects.
• Type 410 stainless steel is hardened through heat treatment, giving it the mechanical strength needed to drill through steel substrates - a capability that standard stainless alloys like 316 or 305 do not typically offer, making this the right choice where both drilling performance and corrosion resistance matter.
• The full-thread machine-screw design combined with a fine 24 TPI pitch means more thread engagement per inch of shank depth, resulting in a more secure pull-out resistance in light-gauge steel framing compared to coarser thread fasteners.
• The supplemental corrosion-protection coating on the 410 stainless body extends service life in applications where moisture contact is possible - making this screw appropriate for interior framing environments where long-term durability is a consideration.

Frequently Asked Questions

What do the wings on this screw actually do during installation?

The wings are positioned just above the drill point. As the screw enters the wood or panel layer, the wings cut a clearance hole so the workpiece material does not bind and climb up the shank. When the drill point reaches and engages the steel stud beneath, the wings break off cleanly - allowing the screw to pull the panel tight against the steel without interference.

Is Type 410 stainless steel strong enough to drill through steel studs without a pilot hole?

Yes. Type 410 stainless steel can be hardened through heat treatment, which gives it the hardness and toughness needed to self-drill through steel substrates. This is what makes it suitable for direct panel-to-steel-stud fastening applications where a separate pre-drilled pilot hole would otherwise be required.

How does the corrosion resistance of Type 410 stainless compare to other stainless grades?

Type 410 stainless steel does not offer the same level of corrosion resistance as Type 316 or Type 305 stainless steel. However, these screws include an additional corrosion-protection coating applied over the 410 base material, which provides supplemental protection against moisture and mild corrosive exposure beyond what uncoated 410 would offer on its own.

What driver bit is needed to install this screw?

This screw uses a #2 Phillips drive, which is one of the most widely available driver bit sizes. A standard #2 Phillips bit in a drill or impact driver is all that is required for installation - no specialty drive tools are needed.
