HirtuOtter: Better and Easier Fastening Solutions
Tired of screws that rust, strip, or fail? We focus on quality materials and thoughtful design to help you get the job done right.

Genuine 304 Stainless Steel Construction
Made from authentic 18-8 stainless steel, these screws offer dependable corrosion resistance for both indoor and outdoor use. Ideal for applications where rust resistance matters—from outdoor furniture and marine environments to household repairs and DIY projects.
Note: 304 stainless may show slight magnetism due to cold working during manufacturing. This is normal and does not affect rust-resistant performance.
Self-Tapping Threads for Clean Installation
The sharp tip and deep threads cut smoothly into wood, metal, plastic, and 3D prints. For soft materials like pine or thin sheet metal, no pre-drilling is needed. For hardwoods or thick metals, we recommend pre-drilling a pilot hole to prevent splitting and protect the screw head.
Precision Phillips Head + Free Matching Bit
Each screw features a deeply machined Phillips head for a secure grip and reduced cam-out. Every pack includes a complimentary driver bit precision-matched to your screw size—so you can start driving right away with no searching for tools.
Durable Storage Case
Your screws and included bit arrive in a sturdy snap-shut plastic case that keeps everything organized, protected, and ready for your next project.
Trusted for a Variety of Projects
From RV repairs and HVAC installations to woodworking, 3D printing, speaker cabinets, and outdoor furniture—HirtuOtter screws deliver reliable holding power across applications.
