S-95452A134 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating for extended service life in demanding wood applications
• Enhanced torque transmission through external hex drive design, preventing tool slippage during installation
• Optimized wood holding power with partially threaded configuration that maximizes pull-out resistance
• Reduced splitting risk thanks to thread forming technology that displaces material without cutting wood fibers
• Industry-standard compatibility with 7 threads per inch specification ensuring proper fit and engagement
• Deep penetration capability with 2½" minimum thread length for secure fastening in thick wood materials
• Quick alignment and starting provided by pointed tip design for efficient installation workflow

Professional Applications & Engineering Value

Engineered for heavy-duty wood fastening applications, these 3/8" diameter wood screws deliver exceptional performance in construction, furniture manufacturing, and structural wood assemblies. The black oxide steel construction provides reliable corrosion protection in environments where moisture exposure is a concern, while the external hex drive system ensures maximum torque application without cam-out issues. The partially threaded design creates superior clamping force by allowing the unthreaded shank to act as a dowel, preventing wood components from shifting under load. This thread forming technology eliminates chip removal concerns and creates stronger thread engagement by compressing wood fibers rather than cutting them, making these screws ideal for hardwood applications where traditional cutting screws might struggle.

Specification Summary & Compliance

This 3/8" x 4" wood screw features precise inch system measurements with 0.375" thread diameter and 7 threads per inch specification. Manufactured to meet ASME B18.2.1 standards for dimensional accuracy and performance requirements. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility and regulatory adherence for industrial distribution. The right-hand thread direction and 2½" minimum thread length provide consistent fastening performance across all wood applications.
