S-94048A236 Length 4 1/2" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from hot-dipped galvanized steel coating, ensuring long-term durability in humid or outdoor wood applications.
• High-torque installation capability with external hex drive and hex head design for secure, slip-resistant driving with standard tools.
• Enhanced holding power through thread forming design that displaces material without pre-drilling, reducing wood splitting in dense materials.
• Optimized load distribution with partially threaded shank, concentrating grip strength at critical connection points.
• Industry-standard compatibility with 1/4"-10 thread size and right-hand threading, ensuring reliable performance in various wood fastening scenarios.
• Extended service life from robust 4-1/2" length and pointed tip, providing deep penetration for structural wood assemblies.
• Regulatory peace of mind with compliance to ASME, ASTM, and SAE standards plus RoHS/REACH environmental directives.

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws address critical challenges in heavy-duty wood construction and industrial applications. The thread forming design eliminates the need for pre-tapped holes while minimizing wood fiber damage, particularly valuable in hardwood framing and outdoor timber structures. The external hex drive configuration delivers maximum torque transmission without cam-out issues, essential for high-volume assembly operations. With 4-1/2" length and partial threading, these fasteners provide superior pull-out resistance in deck building, formwork construction, and structural timber connections where vibration resistance and long-term integrity are paramount. The zinc-rich galvanized coating creates a sacrificial barrier against environmental exposure, making these screws ideal for marine environments, agricultural buildings, and other demanding applications.
