S-90294A198 Length 7/8" Wood Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel ensures long-lasting performance in humid or outdoor wood applications, reducing maintenance costs.
• Thread forming design creates strong, secure threads in wood without pre-tapping, minimizing splitting and improving pull-out resistance.
• Partially threaded shank allows the screw to draw materials tightly together for enhanced clamping force and joint stability.
• Flat head with 82° countersink angle sits flush with wood surfaces for a clean, professional finish and prevents snagging.
• Phillips No. 2 drive provides common, reliable tool compatibility and efficient installation with reduced cam-out risk.
• Optimized for both hardwood and softwood with specific drill bit sizes (3/32" for hardwood, 5/64" for softwood) to prevent wood damage.
• RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for global industrial use.

Professional Applications & Engineering Value

These No. 8 x 7/8" wood screws are engineered with 18-8 stainless steel to combat rust and corrosion in demanding environments like outdoor furniture, decking, and marine woodwork. The flat head Phillips design and partial threading deliver superior holding power by pulling wood components tightly together, reducing joint failure. With a thread forming tapping method, they eliminate the need for separate tapping operations, speeding up assembly while minimizing wood splitting in both hardwood and softwood applications. The precise 82° countersink angle ensures a seamless finish, making them ideal for visible installations where aesthetics matter. Compliant with RoHS and REACH, they meet strict environmental standards for industrial procurement.
