S-90006A112 Length 5/8" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
• Superior holding power through thread forming technology that creates strong, permanent threads in wood materials
• Flush installation capability with standard flat head profile and 82° countersink angle for clean, professional finishes
• Optimized wood grip with partial threading design that prevents wood splitting while maintaining maximum pull-out resistance
• Versatile material compatibility with specific drill bit sizes for both hardwood (1/16") and softwood (3/64") applications
• Easy installation with pointed tip and right-hand threading for quick, straightforward driving into wood substrates
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe, sustainable manufacturing

Professional Applications & Engineering Value

These No. 4 wood screws are engineered to address common challenges in wood fastening applications, particularly material splitting and insufficient holding power. The thread forming technology creates precise, compressed threads in wood fibers without removing material, resulting in significantly enhanced pull-out resistance compared to conventional wood screws. The zinc-plated steel construction provides reliable corrosion protection for interior applications where moisture exposure may occur. The partially threaded design allows the unthreaded shank to act as a pivot point, drawing wood components tightly together while minimizing stress concentration that leads to cracking. With specific drill bit recommendations for both hardwood and softwood, these screws deliver consistent performance across various wood densities commonly encountered in furniture manufacturing, cabinetry, and general woodworking projects.

Specification Summary & Compliance

This No. 4 x 5/8" wood screw features precise inch system measurements with 0.112" thread diameter and 22 threads per inch for optimal wood engagement. The flat head design incorporates an 82° countersink angle matching standard woodworking practices. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance. The thread forming method and right-hand thread direction follow industry-standard fastening principles for wood applications.
