S-98685A560 Length 1" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with durable brass construction for long-lasting performance in humid or outdoor wood applications
• Enhanced thread forming design creates strong, permanent threads in wood without pre-tapping for faster installation
• Optimized partial threading provides maximum holding power while reducing wood splitting in delicate applications
• Precision Phillips No. 1 drive ensures secure tool engagement and reduced cam-out during installation
• Rounded head profile offers flush finishing and professional appearance for visible wood fastening applications
• Dual drill size compatibility works with both hardwood (1/16") and softwood (3/64") projects for versatile application
• Full regulatory compliance meets RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 4 brass wood screws are engineered to address common wood fastening challenges, including material splitting, corrosion concerns, and installation efficiency. The thread forming technology eliminates the need for separate tapping operations, creating strong internal threads that maximize pull-out resistance in both hardwood and softwood applications. The 0.112" thread diameter with 22 TPI (threads per inch) provides optimal thread engagement without compromising wood integrity. The corrosion-resistant brass material ensures reliable performance in environments where moisture or chemical exposure would degrade standard steel fasteners. The partially threaded design concentrates holding power where needed most while minimizing stress concentration points that can lead to wood cracking, making these screws ideal for fine woodworking, furniture assembly, and architectural wood elements requiring both strength and aesthetic appeal.
