S-91550A316 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various woodworking environments.
• Enhanced driving efficiency with dual Phillips/Square drive options (No. 1/No. 2), reducing cam-out and tool slippage for faster installation.
• Optimal material engagement through thread forming technology and 18 TPI design, providing exceptional holding power in plywood and OSB.
• Flush, professional finish with a standard flat head profile and 90° countersink angle, allowing for seamless surface integration.
• Quick, precise starts thanks to the fully threaded, pointed tip and compatibility with 1/16" drill bits, minimizing pre-drilling errors.
• Reliable dimensional consistency with a 0.138" thread diameter and 1/2" length, ensuring uniform performance across applications.
• Environmental compliance assurance by meeting RoHS 3 standards, supporting safe and sustainable procurement practices.

Professional Applications & Engineering Value

These No. 6 wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and weak fastening in engineered wood products. The zinc-plated steel material offers durability against moisture, while the thread forming design creates tight, secure threads in plywood and oriented strand board (OSB) without pre-tapping. The flat head with a 90° countersink ensures a smooth, flush finish, ideal for cabinetry, furniture assembly, and structural applications where appearance and strength are critical. The combination of a pointed tip and full threading enables rapid, vibration-resistant installations, reducing labor time and improving project reliability.

Specification Summary & Compliance

This product features a 0.138" thread diameter with approximately 18 threads per inch and a 1/2" length, adhering to standard inch measurements for precise fit. The flat head design includes a standard profile and 90° countersink angle, compatible with common drill bits (1/16" recommended). Manufactured with thread forming technology and right-hand threading, it ensures consistent performance in wood applications. Compliant with RoHS 3 (2015/863/EU) regulations, supporting environmental and safety standards in industrial and construction use.
