S-90252A249 Length 5/8" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with Black-Oxide Steel coating, extending service life in various woodworking environments
• Superior holding power through thread forming technology that creates strong, permanent threads in fiberboard and particleboard
• Flush, professional installation ensured by the precise 82° countersink angle that prevents surface protrusion
• Maximum material engagement with fully threaded design that distributes load evenly along the entire screw length
• Secure driving control provided by Phillips No. 2 drive that reduces cam-out during installation
• Optimized for wood materials with pointed tip design that facilitates easy starting and precise placement
• Pre-drilling compatibility with standard 5/64" drill bits for clean, accurate hole preparation

Professional Applications & Engineering Value

This heavy-duty No. 8 wood screw is specifically engineered to address common challenges in fiberboard and particleboard applications where material density variations can compromise fastener performance. The Black-Oxide Steel construction provides essential corrosion protection in environments where moisture or humidity may be present, while the thread forming technology creates compressed, high-strength threads that significantly outperform conventional cutting threads in composite wood materials. The precision 82° countersink angle ensures complete flush mounting with standard flat head applications, eliminating surface protrusions that can damage equipment or create safety hazards. The fully threaded design maximizes pull-out resistance by engaging material throughout the entire screw length, making it ideal for applications requiring exceptional grip strength in wood materials where vibration or dynamic loads are concerns.

Specification Summary & Compliance

This No. 8 wood screw features standard inch measurements with 0.164" thread diameter and 11 threads per inch configuration. The flat head design maintains proper head diameter tolerance of -0.04" for consistent performance. Manufactured with right-hand threading and standard flat head profile, this screw is compatible with conventional installation tools and techniques. The product meets industry standards for wood screw applications and is designed for use with 5/64" drill bits (0.078" diameter) as specified for proper hole preparation in composite wood materials.
