Key Features & Benefits at a Glance
- Self-drilling tip eliminates pre-drilling, saving time and labor costs in wood assembly projects
- Corrosion-resistant 18-8 stainless steel construction ensures long-lasting performance in humid or outdoor environments
- Square drive design provides superior torque transmission and reduces cam-out during installation
- Thread cutting tapping method creates clean, secure threads in wood for reliable, vibration-resistant fastening
- Locking serrations under the flat head prevent loosening under dynamic loads and vibration
- 90° countersink angle allows for flush mounting in standard countersunk holes
- Partial threading with 2" minimum thread length provides optimal grip strength while reducing driving resistance
Professional Applications & Engineering Value
These No. 8 self-drilling wood screws are engineered to solve common fastening challenges in wood construction and manufacturing. The combination of 18-8 stainless steel material and thread cutting design ensures reliable performance in demanding applications where corrosion resistance and strong holding power are critical. The square drive system delivers maximum torque transfer, preventing tool slippage and damaged screw heads during high-volume installation. With their self-drilling tip and partial threading, these screws significantly reduce installation time while providing secure fastening in furniture assembly, deck building, and structural wood framing applications. The flat head with 90° countersink creates a clean, finished appearance while the locking serrations maintain clamp force under vibration.
Specification Summary & Compliance
These screws feature a No. 8 size with 0.164" thread diameter and 8 threads per inch in right-hand thread direction. The partially threaded design provides a 2" minimum thread length on a 3" overall screw. Manufactured to precise dimensional standards with Class 2A thread fit for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and commercial applications.
