S-90294A112 Length 5/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in humid or outdoor wood applications.
• Enhanced holding power through thread forming design, which compacts wood fibers for a tighter, more secure fastening without pre-tapping.
• Clean, flush installation with a standard 82° flat head profile and countersink angle, providing a smooth finish in wood surfaces.
• Efficient drive engagement using a Phillips No. 1 drive, reducing cam-out risks and enabling quick, straightforward installation.
• Optimized for various wood types with specific drill bit recommendations (1/16" for hardwood, 3/64" for softwood) to prevent splitting and ensure precise fit.
• Durable partial threading (0.448" min thread length) on a pointed tip, allowing for easy starting and strong grip in wood materials.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries and sustainable projects.

Professional Applications & Engineering Value

These No. 4 x 5/8" stainless steel wood screws are engineered to address common fastening challenges in woodworking and construction. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making them ideal for outdoor furniture, decking, and marine applications where moisture exposure is a concern. The thread forming tapping method eliminates the need for separate tapping operations by displacing wood fibers to create strong, permanent threads that resist loosening under vibration. Combined with a Phillips drive style and flat head design, these screws ensure easy installation with standard tools while providing a flush finish that enhances aesthetic appeal. Whether used in hardwood or softwood, the precise 82° countersink angle and pointed tip facilitate quick alignment and reduce the risk of material damage, saving time and improving project efficiency in cabinetry, framing, and joinery tasks.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.112" and approximately 22 threads per inch, ensuring consistent fit. The partially threaded design with a right-hand thread direction follows common industrial practices for wood fasteners. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms the absence of hazardous substances, supporting environmental safety and regulatory requirements in global markets.
