S-90031A410 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior holding power in wood applications through advanced thread forming technology that creates strong, permanent threads without pre-tapping
• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term durability in various environmental conditions
• Optimal countersinking capability with 82° flat head profile that sits flush with wood surfaces for professional finishing
• Reduced installation effort with Phillips drive design providing secure tool engagement and efficient driving performance
• Versatile wood compatibility with specific drill bit recommendations for both hardwood (3/16") and softwood (9/64") applications
• Reliable partial threading design that allows unthreaded shank to pull materials tightly together for maximum clamping force
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated manufacturing

Professional Applications & Engineering Value

These No. 18 wood screws are engineered specifically for demanding wood fastening applications where maximum holding power and reliable performance are critical. The zinc-plated steel construction provides essential corrosion protection for both interior and exterior wood projects, while the thread forming technology eliminates the need for pre-tapped holes - the screws create their own perfectly matched threads as they're driven, resulting in superior pull-out resistance and reduced installation time. The Phillips flat head design ensures clean, flush mounting in wood surfaces, making these partially threaded screws ideal for furniture assembly, cabinetry, deck building, and general construction where wood-to-wood connections require professional-grade fastening solutions. The specific drill bit sizing for hardwood and softwood applications further enhances installation precision and prevents wood splitting.

Specification Summary & Compliance

These inch-system wood screws feature a No. 18 screw size with 0.294" thread diameter and 8 threads per inch in right-hand orientation. The partially threaded design provides 1.667" minimum thread length on the 2-1/2" overall length, with standard flat head profile and No. 4 Phillips drive compatibility. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring these fasteners meet current international standards for restricted substances and chemical safety.
