S-90396A180 Length 3 1/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in wood applications.
• Enhanced torque transmission and reduced cam-out thanks to the T15 Torx drive, ensuring efficient installation and driver bit longevity.
• Increased holding power and stability from the integrated flange, which acts as a built-in washer for a more secure fit.
• Secure, vibration-resistant fastening in wood achieved through thread forming technology that creates strong, permanent threads without pre-drilling.
• Easy and precise starting provided by the pointed tip and partial threading, allowing for quick alignment and reduced material splitting.
• Reliable performance in demanding environments ensured by compliance with RoHS 3 and REACH environmental and safety regulations.
• Optimized for deep penetration with a 3-1/8" length and 2.087" minimum thread length, ideal for thick wood assemblies.

Professional Applications & Engineering Value

These No. 8 wood screws are engineered to solve common fastening challenges in woodworking and construction. The zinc-plated steel material provides a durable barrier against rust and corrosion, which is critical for both indoor and outdoor applications where moisture exposure can compromise fastener integrity. The T15 Torx drive system delivers maximum torque transfer, minimizing the risk of stripped heads and improving installation speed in high-volume projects like furniture assembly, deck building, and structural framing. The thread forming design displaces wood fibers to create a tight, permanent grip that resists loosening from vibration and load stress, eliminating the need for tapping and reducing labor time. Combined with the flanged head, these screws distribute clamping force evenly, preventing surface damage and ensuring a flush, professional finish in soft and hardwoods alike.
