S-98643A653 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Effortless installation with self-drilling tip that eliminates pre-drilling, saving time and labor costs in wood applications
• Superior corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in various environmental conditions
• Secure, cam-out resistant fastening with square drive design that provides maximum torque transfer and prevents tool slippage
• Clean, flush finishing thanks to the flat head with 90° countersink angle that sits perfectly flush with wood surfaces
• Excellent thread engagement through thread cutting tapping method that creates strong, permanent connections in wood materials
• Enhanced anti-loosening performance with serrations under the head that provide additional locking security
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable industrial use

Professional Applications & Engineering Value

These No. 8 self-drilling wood screws are engineered to solve common wood fastening challenges in construction, furniture manufacturing, and outdoor structures. The 18-8 stainless steel composition provides exceptional resistance to rust and corrosion, making them ideal for humid environments or exterior applications where durability is critical. The combination of thread cutting tapping method and self-drilling tip eliminates the need for pilot holes while creating precise, strong threads in wood substrates. This reduces installation time by up to 50% compared to traditional wood screws while preventing material splitting. The square drive system ensures maximum torque transmission without cam-out, allowing for consistent seating and flush installation with the 90° countersink angle flat head design. These features make them particularly valuable for production environments where efficiency, reliability, and clean aesthetics are paramount.

Specification Summary & Compliance

These screws feature a No. 8 size with 1-1/2" length and partial threading with approximately 8 threads per inch. The right-hand thread configuration follows standard wood screw specifications. Manufacturing complies with industry standards for dimensional accuracy, including proper head diameter (0.311") and thread diameter (0.164") tolerances. The products are fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring they meet the latest environmental regulations for hazardous substance restrictions.
