S-95452A158 Length 5 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel construction for extended service life in demanding wood applications
• Maximum torque transmission through external hex drive design, preventing tool slippage during installation
• Enhanced holding power with thread forming technology that creates strong, permanent threads in wood materials
• Optimized load distribution with partial threading design that concentrates gripping strength where needed most
• Quick and secure installation with pointed tip that initiates precise thread formation without pre-drilling
• Heavy-duty performance with substantial 5/8" diameter and 5 1/2" length for structural wood connections
• Industry-standard compatibility with 0.938" hex head dimensions for use with standard wrench and socket tools

Professional Applications & Engineering Value

Engineered for heavy-duty wood fastening applications, these black oxide steel hex head wood screws deliver exceptional performance in structural timber construction, outdoor decking, and industrial wood assemblies. The thread forming design eliminates the need for pre-tapped holes while creating superior pull-out resistance by compressing wood fibers rather than removing material. The external hex drive system provides maximum torque capability for high-clamp load applications, preventing cam-out issues common with other drive types. With partial threading and substantial 5/8" diameter, these screws concentrate gripping power in the engagement zone while the smooth shank reduces splitting in sensitive wood materials. Ideal for construction professionals requiring reliable, high-strength connections in timber framing, heavy equipment bases, and industrial wood structures.

Specification Summary & Compliance

This 5/8" x 5 1/2" wood screw features precision right-hand threads with approximately 5 threads per inch and meets ASME B18.2.1 specifications for dimensional accuracy and performance standards. The product maintains compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. Manufactured from black oxide coated steel with external hex drive (0.938" width) and partial threading extending 3 1/4" from the pointed tip, ensuring reliable performance in industrial wood fastening applications.
