Frequently Asked Questions

Do I need to pre-drill holes before using these screws? ▼
No! The Type 17 self-drilling point eliminates the need for pre-drilling in most wood applications. The auger-style point creates its own pilot hole as you drive the screw, reducing installation time by 30-40% and preventing wood splitting. This makes them ideal for fast-paced construction work where efficiency is critical.
What's the difference between Yellow Zinc, Bronze, and Stainless Steel finishes? ▼
Yellow Zinc (featured) provides 100+ hours salt spray protection and is ideal for general outdoor use with professional appearance. Bronze offers enhanced corrosion resistance with premium aesthetics for visible applications. Stainless Steel provides maximum corrosion resistance for coastal, marine, or high-moisture environments. All finishes work identically - choose based on environmental exposure and appearance preferences.
Can these screws be used for outdoor applications in Oregon weather? ▼
These screws are specifically engineered for Pacific Northwest conditions. The yellow zinc coating provides superior corrosion resistance through Oregon's wet winters and humid conditions. For extra protection in coastal areas or constant moisture exposure, consider upgrading to Bronze or Stainless Steel finishes. Our Damascus location can provide specific recommendations based on your project's environment.
What applications are these 3-1/2" screws best suited for? ▼
The 3-1/2" length is ideal for structural wood connections including joist and beam attachments, deck framing, subfloor installation, wall sheathing, fence construction, and general wood framing. The penetration depth provides excellent holding power for 2x lumber connections and engineered wood products. Perfect for both professional contractors and serious DIY builders.
Do these screws work in hardwood as well as softwood? ▼
Yes! The Type 17 point and coarse thread design work excellently in both softwood (pine, fir, cedar) and hardwood (oak, maple, mahogany) applications. The self-drilling point creates clean entry even in dense hardwoods, though using a power driver is recommended for hardwood installations. For extremely dense exotic hardwoods, pilot holes may improve results.
Are contractor quantity discounts available? ▼
Yes! We offer volume pricing for contractors and bulk orders. These screws are typically available in boxes of 100, 250, and 1000 pieces with progressive discounts at each tier. Contact our Damascus location at 503-496-7017 for current contractor pricing and to discuss your specific project requirements. Same-day pickup available for in-stock quantities.
What size Phillips driver bit should I use? ▼
A #2 Phillips bit is the standard size for these construction screws and provides optimal torque transfer. For best results, use impact-rated Phillips bits which resist cam-out and last significantly longer than standard bits. We recommend keeping multiple bits on hand for large projects to maintain optimal driving performance throughout your installation.
Is same-day pickup available? ▼
Yes! Same-day pickup is available at our Damascus OR location for in-stock items. Call ahead at 503-496-7017 to confirm quantity availability and we'll have your order ready when you arrive. Business hours are Monday - Friday 7:00 AM - 4:00 PM. Our team can also provide expert guidance on finish selection and application recommendations.
