S-93225A467 4-40 x 1/2" Threaded Rods

Key Features & Benefits at a Glance

• Lightweight yet durable construction using 6061 aluminum for easy handling without compromising structural integrity in demanding environments.
• Precise thread engagement with Class 1A fit ensures smooth assembly and reduces cross-threading risks during installation.
• Full-length threading provides consistent fastening capability along the entire 1/2" length for versatile positioning and adjustment.
• High tensile strength of 40,000 psi delivers reliable load-bearing performance for mechanical and structural applications.
• Uniform hardness (Rockwell B40) maintains thread integrity and resists deformation under repeated use.
• Coarse UNC thread profile offers quick installation and superior resistance to vibration loosening in dynamic systems.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and suitability for global industrial supply chains.

Professional Applications & Engineering Value

This 4-40 UNC threaded rod in 6061 aluminum addresses critical needs in precision assembly and lightweight framing. The fully threaded design with coarse UNC spacing enables rapid adjustments in machinery, electronic enclosures, and prototyping fixtures where weight reduction is paramount. Its Class 1A thread fit guarantees compatibility with standard nuts, minimizing tolerance stack-up in multi-component systems. Engineers value the 40,000 psi tensile strength and Rockwell B40 hardness for maintaining clamp load in vibratory environments, while the right-hand thread direction aligns with conventional installation tools. Ideal for aerospace components, optical mounts, and automated equipment, this rod combines corrosion-resistant aluminum properties with rigorous dimensional consistency.
