S-98643A657 Length 4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in humid or outdoor wood applications
• Enhanced torque transfer and reduced cam-out thanks to the square drive design, allowing for secure installation and removal
• Efficient thread-cutting action that creates precise mating threads in wood, minimizing splitting and providing maximum holding power
• Flush, professional finish with a standard 90° flat head profile that sits seamlessly in countersunk holes
• Reliable anti-rotation locking through serrations under the head, preventing loosening under vibration in wood structures
• Optimized drilling and fastening with a self-drilling tip and partially threaded shank for controlled penetration and reduced driving effort
• Environmental and regulatory safety with full compliance to RoHS 3 and REACH standards, ensuring safe use in various industries

Professional Applications & Engineering Value

These No. 10 x 4" wood screws are engineered to address common challenges in wood fastening, such as material splitting, corrosion in outdoor settings, and inefficient installation. The 18-8 stainless steel material offers excellent durability against moisture and chemicals, making these flat head screws ideal for decking, furniture, and structural wood assemblies. The thread-cutting design and square drive work in tandem to reduce operator fatigue while ensuring a tight, vibration-resistant fit. With a drilling tip that eliminates pre-drilling needs and serrations for enhanced grip, these screws deliver consistent performance in both soft and hardwoods, streamlining projects from construction to cabinetry.

Specification Summary & Compliance

This screw features a No. 10 size with a 0.19" thread diameter and approximately 8 TPI in a right-hand thread direction, adhering to standard inch measurements. The partially threaded shank and 2.625" minimum thread length ensure optimal grip in wood. Manufactured to meet industry expectations for dimensional accuracy, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility.
