S-91478A814 Length 5" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in demanding wood applications.
• Superior torque transmission and strip-resistant installation provided by the external hex drive and robust hex head design.
• Exceptional holding power in wood due to the thread forming tapping method, which creates strong, secure threads without pre-drilling in many cases.
• Optimized for heavy-duty fastening with a substantial 5" length and 5/8" diameter, ensuring deep penetration and a reliable grip.
• Efficient installation and alignment with a pointed tip and partially threaded shank for easier starting and controlled clamping force.
• Guaranteed dimensional consistency and interchangeability, manufactured to meet the rigorous ASME B18.2.1 standard.
• Safe for regulated environments as they are compliant with RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve critical fastening challenges in wood construction and industrial assembly. The zinc-plated steel material provides a durable barrier against rust and corrosion, essential for both indoor and outdoor applications. The external hex drive and hex head work in tandem to deliver maximum torque application, preventing cam-out and ensuring the screw is driven to its full seating depth without head stripping. The thread forming design is particularly valuable as it displaces wood material to create a tighter, more secure fit with higher pull-out resistance compared to thread-cutting alternatives. This makes them ideal for structural framing, timber construction, and heavy furniture assembly, where failure is not an option. The combination of a 5/8" diameter and 5" length offers a robust fastening solution for joining thick lumber and engineered wood products with confidence.

Specification Summary & Compliance

This screw features a 5/8" thread diameter with approximately 5 threads per inch (TPI) and a right-hand thread direction. It is partially threaded with a minimum thread length of 3" and an overall length of 5". The dimensional integrity and manufacturing quality are ensured by conformity to the ASME B18.2.1 standard. Furthermore, this product is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for industrial components.
