S-90031A554 Length 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in humid or outdoor wood applications
• Enhanced pull-out resistance through thread forming design that compresses wood fibers without pre-tapping
• Clean, flush installation with standard 82° flat head profile and Phillips No. 2 drive for professional finishing
• Reduced wood splitting with partial threading that maintains shank strength while minimizing material stress
• Optimized for both hardwood and softwood with specific drill bit size recommendations (5/64" for hardwood, 1/16" for softwood)
• Secure regulatory compliance meeting RoHS 3 and REACH standards for industrial safety requirements
• Precise thread engagement with 18 TPI and pointed tip for straight starts and consistent driving performance

Professional Applications & Engineering Value

These black-oxide steel wood screws solve critical fastening challenges in furniture manufacturing, cabinetry, and structural wood assemblies. The thread forming design eliminates the need for pre-tapped holes while creating permanent, vibration-resistant connections that won't loosen over time. The partial threading configuration provides maximum holding power in the engagement zone while maintaining full shank strength to prevent shear failures. With precise 82° countersink angles and Phillips drive compatibility, these screws ensure flush installations without surface protrusions, making them ideal for visible applications where aesthetics matter. The corrosion-resistant black-oxide finish protects against moisture absorption in both indoor and outdoor wood projects.

Specification Summary & Compliance
