S-93306A722 1/2"-13 x 2 1/2" Aluminum Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional lightweight strength with 2024 aluminum construction, providing high tensile strength (30,000 psi) while reducing component weight for easier handling and assembly.
• Superior corrosion resistance inherent in 2024 aluminum, ensuring long-term durability and reliability in harsh industrial environments without heavy coatings.
• Precise and reliable fastening with Class 2A thread fit and UNC coarse threads, enabling quick installation and secure connections with reduced cross-threading risk.
• Optimized torque transmission through the external hex drive and 3/4" head width, allowing for high tightening forces with standard tools and minimizing slippage.
• Full-thread engagement capability along the 2 1/2" length, ensuring maximum grip and load distribution across connected materials.
• Consistent performance under stress backed by Rockwell B40 hardness, maintaining thread integrity and resistance to deformation during repeated use.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and export markets.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 2024 aluminum hex head screws address critical needs for lightweight yet high-strength fastening. The UNC coarse thread design facilitates rapid assembly in soft materials or where vibration resistance is paramount, while the external hex drive ensures compatibility with common wrenches for efficient maintenance. Ideal for aerospace, automotive, and machinery sectors, the fully threaded construction and Class 2A thread fit provide uniform stress distribution, reducing the risk of joint failure. Their inherent corrosion resistance eliminates the need for additional plating, offering a cost-effective solution for environments exposed to moisture or chemicals without compromising on the 30,000 psi tensile strength required for structural integrity.
