S-90610A723 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in demanding woodworking environments
• Enhanced thread engagement through thread forming technology creates stronger, more secure connections in wood materials
• Clean, flush installation with 82° countersink angle and flat head design for professional, finished appearances
• Optimized wood penetration with pointed tip and partial threading for reduced splitting and improved holding power
• Secure torque transmission via square drive design that minimizes cam-out and driver slippage
• Material-specific performance with recommended drill bit sizes for both hardwood and softwood applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated use

Professional Applications & Engineering Value

These No. 8 wood screws with black-oxide steel construction address critical woodworking challenges where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for pre-tapped holes while creating stronger thread engagement through material displacement rather than removal. This results in superior holding power in both hardwood and softwood applications, reducing the risk of pull-out in structural joints. The 82° countersink angle ensures flush mounting in standard countersunk holes, while the square drive system provides maximum torque transfer without stripping. These engineering features make them ideal for furniture manufacturing, cabinetry, deck building, and other professional woodworking applications where reliability and clean finishes are essential.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with 0.164" thread diameter and 15 threads per inch, these partially threaded screws feature right-hand threading and standard flat head profile. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current international standards for restricted substances. The thread forming tapping method and specified drill bit sizes (3/32" for hardwood, 5/64" for softwood) provide guidance for optimal installation performance in various wood materials.
