S-92406A110 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with solid brass construction, ideal for humid environments and outdoor wood applications
• Enhanced holding power through thread forming technology that creates stronger, more secure connections in wood
• Clean, flush installation with 82° countersink angle and standard flat head profile for professional finishing
• Optimized for both hardwood and softwood with specific drill bit size recommendations (1/16" for hardwood, 3/64" for softwood)
• Reduced splitting risk with partially threaded design that minimizes wood stress during installation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing
• Traditional installation compatibility with slotted drive design for standard screwdriver applications

Professional Applications & Engineering Value

These No. 4 brass wood screws deliver exceptional performance in woodworking and cabinetry applications where corrosion resistance and aesthetic appeal are paramount. The thread forming technology eliminates the need for pre-tapped holes while creating stronger, more permanent connections by compressing wood fibers rather than removing them. This design significantly reduces the risk of wood splitting, particularly in delicate hardwoods and fine furniture projects. The 82° countersink angle ensures heads sit flush with wood surfaces, providing clean, professional finishes without protruding hardware. The partially threaded configuration allows for precise clamping force control, making these brass flat head screws ideal for joinery, trim work, and restoration projects where material integrity cannot be compromised.

Specification Summary & Compliance

These inch-measurement wood screws feature a No. 4 size with 0.112" thread diameter and 22 threads per inch configuration. The flat head slotted design follows standard profiles with 0.225" head diameter and 0.067" head height. Manufactured to precise dimensional standards with right-hand threading and partially threaded shank (minimum 0.333" thread length). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met.
