S-90031A563 Length 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, extending screw life in various woodworking environments.
• Enhanced holding power through thread forming design, creating strong, permanent threads without pre-tapping in wood.
• Clean, flush installation with 82° countersink angle and flat head profile, preventing surface protrusions and snagging.
• Efficient driving with reduced cam-out using Phillips No. 2 drive, ensuring secure bit engagement and faster assembly.
• Optimized for both hardwood and softwood with specific drill bit size recommendations (3/32" for hardwood, 5/64" for softwood) for precise, split-free installations.
• Reliable partial threading providing strong grip in the threaded section while allowing unthreaded shank to pull materials tightly together.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in industrial applications.

Professional Applications & Engineering Value

These No. 8 wood screws with Black-Oxide Steel construction and thread forming technology address common wood fastening challenges by eliminating the need for separate tapping operations. The partially threaded design ensures that the unthreaded shank pulls wood components together tightly before the threads engage, preventing material separation under stress. With precise 82° countersink angle and flat head profile, they sit flush in hardwood and softwood applications—from furniture manufacturing to structural wood assemblies—reducing installation time and minimizing surface damage. The Phillips drive provides reliable torque transfer, while the pointed tip facilitates accurate placement, making them ideal for high-volume production environments where consistency and durability are critical.

Specification Summary & Compliance

These screws feature a 0.164" thread diameter with approximately 15 threads per inch and 1/2" minimum thread length, ensuring precise engagement in wood materials. Manufactured to standard inch measurements with right-hand threading and partially threaded configuration for optimal performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial use.
