#8 x 3" Conquest T15 Trim Head Deck Screws - 316 Stainless Steel, Pkg. 1,750

The #8 x 3 inch Conquest T15 Trim Head Deck Screw in 316 stainless steel is built for large deck and marine installations where corrosion resistance is critical. Engineered for strength and a clean appearance, it performs reliably in coastal and high-humidity environments. This 1,750-count bulk package keeps production crews moving.

Bulk #8 3 Inch 316 Stainless Steel Trim Head Deck Screw

Featuring a low-profile trim head and aggressive thread engagement, this screw provides secure fastening with a refined finish. The T15 drive enhances installation control, and the self-starting tip supports fast, efficient driving in dense woods.

Key Features

  • Marine-Grade 316 Stainless: Resists rust and corrosion in salt-air conditions.
  • Trim Head Design: Minimizes surface visibility for a clean look.
  • T15 Drive System: Improves torque transfer and reduces cam-out.
  • Deep Threads: Deliver lasting holding strength in treated lumber.

Common Applications

  • Deck Construction: Secure boards across large coastal builds.
  • Docks and Waterfront Projects: Fasten structural wood near water.
  • Exterior Trim: Attach fascia and finishing components.
  • Fence Installation: Ideal for harsh outdoor environments.
  • Contractor Builds: Bulk packaging supports high-output jobs.

Installation Tips

  • Use a T15 Driver Bit: Match the drive for optimal engagement.
  • Maintain Steady Pressure: Drive smoothly for flush seating.
  • Avoid Over-Tightening: Let threads secure without crushing fibers.

Screws for trex deck

Very good screws that match my material well

Eric Bjorkstedt
Mixed bucket

These screws were perfect for my need (deck construction)… at least those that worked. A substantial fraction had shallow or malformed heads (driver bit would not seat cleanly) and a separate fraction were bent coming out of the bucket—perhaps casualties of rough handling during shipping? If I didn’t catch these misfits immediately (and it took some time to catch the pattern), it was easy to get snared in a skip-n-strip or even a time-wasting screw extraction. Rough estimate: a 10% failure rate. The screws that were well formed worked like a charm.

Thank you for taking the time to provide us with a review. We are sorry to hear that some of these screws did not function properly. Quality of our products is very important to us and we would like to bring this to the attention of our quality department. Please email your order number along with pictures of the product you received to customerservice@fastenersplus.com and we can work with you on a resolution. We look forward to hearing from you and working together on a resolution.
