Simpson Strong-Tie Construction Screws: Professional-Grade Fasteners for Every Trade

When it comes to construction fasteners, having the right screw for the job makes the difference between a solid installation and a callback. Simpson Strong-Tie has built its reputation on engineering fasteners that meet the demanding requirements of professional contractors across all trades. Here's a breakdown of their construction screw lineup and what makes each one suited for specific applications.

Simpson Cement Board Screws

These screws are engineered specifically for attaching cement backer board to wood or light-gauge steel studs. The corrosion-resistant coating handles both interior bathroom applications and exterior sheathing installations. The modified bugle head provides a clean, flush finish without tearing the cement board surface, while the sharp point penetrates cleanly without requiring pilot holes in most applications.

Simpson Concrete Screws

Simpson's masonry screws provide a reliable anchoring solution for attaching fixtures directly into concrete, block, and brick substrates. The hardened steel construction and specialized thread design create strong pullout resistance in masonry materials. These screws eliminate the need for expansion anchors in many applications, making them a time-saver for electrical boxes, brackets, and framing attachments to concrete foundations.

Simpson Deck Screws

Built for outdoor exposure, these screws feature enhanced corrosion protection through advanced coating systems. The deep thread profile maximizes holding power in treated lumber, while the self-countersinking head design prevents mushrooming of deck boards. Available in lengths to handle standard 5/4" decking through 2" material, these screws are engineered to resist the seasonal movement common in outdoor structures.

Simpson Drywall Screws

The key to these screws lies in their specialized thread design, which provides superior holding power in gypsum board without over-driving. The bugle head shape allows for proper embedding below the surface while minimizing paper tearing. Sharp points penetrate metal studs cleanly, and the phosphate coating provides basic corrosion resistance for interior applications.

Simpson Metal Roofing Screws

These screws handle the unique demands of metal roofing and siding installations. The hex washer head with integrated EPDM washer creates a weather-tight seal, while the self-drilling point eliminates pre-drilling in most metal applications. Thread design provides secure attachment in both metal-to-metal and metal-to-wood connections, making them versatile for pole barn construction and commercial roofing projects.

Simpson Pocket Hole Screws

Designed specifically for pocket hole joinery, these screws feature a washer head that distributes clamping force while the sharp point minimizes wood splitting at the joint. The thread design pulls materials tight together for strong wood-to-wood connections in cabinet construction, furniture assembly, and trim work.

Simpson Quik Drive Screws

These collated screws are engineered for use with automatic screw guns, bringing speed and consistency to high-volume installations. Available in various construction screw types, they eliminate the fumbling associated with individual screws while providing the superior holding power screws offer over nails. The collation system ensures consistent installation depth and reduces hand fatigue on large projects.

Simpson Self-Drilling Screws

The drill point on these screws eliminates pre-drilling in steel applications up to specific thicknesses, depending on screw diameter. The combination of drilling and tapping action in one fastener speeds installation in metal framing, HVAC ductwork, and light structural steel connections. Wings on some models help clear debris during drilling for cleaner holes.

Simpson Sheet Metal Screws

These screws are optimized for joining sheet metal components with their sharp piercing points and aggressive thread design. The hex washer heads provide good torque transfer and bearing surface, while various point styles handle different material thicknesses. They're essential for HVAC installations, electrical panel mounting, and general sheet metal fabrication.

Simpson Specialty Stainless Steel Screws

This category includes marine-grade fasteners for coastal applications and truss head screws for general stainless steel needs. The marine screws resist saltwater corrosion for dock construction and boat repair, while the truss head design provides a low-profile connection with good bearing surface for architectural applications where corrosion resistance is critical.

Simpson Structural Wood Screws

These high-strength screws serve as alternatives to lag screws and through-bolts in many structural applications. The aggressive thread design and hardened steel construction provide excellent pullout resistance, while the hex head allows for proper torque application. No pilot hole requirement in many wood species speeds installation compared to traditional lag screws.

Simpson Threaded Rod Hangers

These specialized hangers provide secure attachment points for 1/4" and 3/8" threaded rod in suspended applications. Used extensively for hanging pipe, electrical conduit, fire protection systems, and cable tray, they provide reliable load transfer to structural members while allowing for easy rod installation and adjustment.

Simpson Underlayment & Subfloor Screws

Designed to eliminate floor squeaks and provide superior holding power compared to nails, these screws create tight connections between subfloor panels and joists. The thread design pulls materials together while the head design countersinks properly without over-driving. Ring-shank designs provide additional withdrawal resistance.

Simpson Wood Screws

This broad category includes various head styles and thread designs for general wood construction. From finish screws for trim work to heavy-duty construction screws for framing, these fasteners provide reliable wood-to-wood connections. Different point styles accommodate hardwoods and softwoods, while coating options provide appropriate corrosion resistance for the application.
