S-91478A626 Length 1 1/4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in demanding wood applications
• Maximum torque transmission through external hex drive design prevents stripping and ensures secure installation
• Enhanced holding power with thread-forming technology that creates strong, permanent threads in wood materials
• Complete material penetration with fully threaded design for superior grip and load distribution
• Quick and easy installation with pointed tip that guides the screw accurately without pre-drilling in most applications
• Reliable dimensional consistency meeting ASME B18.2.1 standards for precise fit and predictable performance
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe, sustainable manufacturing

Professional Applications & Engineering Value

These 3/8" diameter wood screws are engineered to solve common fastening challenges in wood construction and assembly applications. The zinc-plated steel construction provides essential corrosion protection, extending service life in environments where moisture exposure is a concern. The thread-forming design eliminates the need for pre-tapped holes while creating superior holding strength by compressing wood fibers rather than removing them. With 7 threads per inch and fully threaded configuration, these external hex drive screws deliver maximum engagement depth and pull-out resistance. The 1-1/4" length provides optimal material penetration for medium-duty wood joining applications, from furniture manufacturing to structural wood assemblies, ensuring reliable performance where vibration resistance and long-term integrity are critical.

Specification Summary & Compliance

These wood screws feature 3/8" thread diameter with 7 threads per inch and 1-1/4" overall length, manufactured to precise dimensional standards. The external hex head (0.563" width, 1/4" height) ensures compatibility with standard wrench and socket tools. Manufactured in compliance with ASME B18.2.1 specifications for dimensional accuracy and performance requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring restricted substance compliance for international markets.
