S-90294A113 Length 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term durability in humid or outdoor woodworking environments.
• Secure, slip-resistant installation thanks to the Phillips drive style and No. 1 drive size, providing reliable torque transfer and reducing cam-out risks.
• Optimal material-specific performance with dedicated drill bit recommendations (1/16" for hardwood, 3/64" for softwood) for clean, precise holes and maximum holding power.
• Flush, professional finish achieved with the standard 82° flat head profile, allowing the screw to sit neatly countersunk in wood surfaces.
• Enhanced pull-out resistance from the thread forming tapping method and 1/2" thread length, which creates strong, permanent threads in wood without pre-tapping.
• Reduced splitting in delicate applications due to the partially threaded shank design, concentrating grip where it's needed most.
• Compliance with stringent environmental regulations, including RoHS 3 and REACH, ensuring safe, responsible sourcing for professional and export-focused projects.

Professional Applications & Engineering Value

These No. 4 x 3/4" wood screws are engineered to address common challenges in wood joinery, such as material splitting, corrosion in damp conditions, and inconsistent fastening strength. The 18-8 Stainless Steel material provides excellent resistance to rust and oxidation, making these Phillips flat head screws ideal for outdoor furniture, decking, marine applications, and high-moisture interior environments. The thread forming design eliminates the need for separate tapping operations in wood, as the screw creates its own precise, strong mating threads—this is particularly valuable in hardwood and softwood applications where thread integrity is critical for load-bearing assemblies. The partially threaded configuration ensures that clamping force is focused at the joint interface, minimizing stress on the surrounding wood fibers and reducing the risk of cracking, especially near edges or in thinner stock.

Specification Summary & Compliance

This screw features a 0.112" thread diameter with approximately 22 threads per inch and a minimum 1/2" thread length. The flat head is designed with an 82° countersink angle for standard flush mounting. Manufacturing and material compliance include adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, confirming the absence of restricted hazardous substances and supporting use in regulated markets and eco-conscious projects.
