S-92406A108 Length 3/8" Wood Screws

Key Features & Benefits at a Glance

• Corrosion-resistant brass construction ensures long-lasting performance in humid or outdoor woodworking environments
• Thread forming design creates stronger, more secure fastenings in wood without pre-tapping requirements
• Standard 82° countersink angle allows for flush mounting and clean, professional-looking finishes
• Partially threaded shank provides superior pull-out resistance while minimizing wood splitting
• Slotted flat head design offers compatibility with traditional screwdrivers for versatile installation
• Precision sizing recommendations (1/16" for hardwood, 3/64" for softwood) ensure optimal performance and reduced material stress
• Environmental compliance with RoHS 3 and REACH standards makes these screws suitable for regulated applications

Professional Applications & Engineering Value

These No. 4 brass wood screws are engineered to address common wood fastening challenges in both hardwood and softwood applications. The thread forming tapping method creates permanent, high-strength threads within the wood fibers, eliminating the need for separate tapping operations while providing exceptional holding power. The partially threaded design concentrates gripping force where it's needed most, reducing the risk of wood splitting in delicate joinery work. The corrosion-resistant brass material maintains structural integrity in environments where moisture or chemical exposure would degrade standard steel fasteners. With precise 22 TPI threading and standardized 82° countersink angle, these screws deliver consistent, professional results in furniture manufacturing, cabinetry, and precision woodworking projects where appearance and durability are equally important.

Specification Summary & Compliance

These screws feature standard inch measurements with 0.112" thread diameter, 3/8" length, and right-hand threading with approximately 22 threads per inch. The slotted flat head design follows conventional drive standards while the partially threaded configuration ensures optimal performance in wood applications. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for professional and consumer applications.
