Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
- Zinc-plated alloy steel construction provides excellent corrosion resistance, extending service life in harsh industrial environments.
- Class 3A thread fit offers superior precision and tighter tolerances for secure, vibration-resistant assemblies.
- Partially threaded design allows for precise clamping force control and easier alignment in specific applications.
- Hex socket drive (5/32") enables high-torque installation with standard tools, minimizing stripping and improving installation efficiency.
- Coarse UNC threading facilitates quicker assembly and disassembly, saving time in maintenance and production cycles.
- Compliance with ASTM A574, RoHS 3, and REACH ensures material consistency, environmental safety, and global regulatory acceptance.
Professional Applications & Engineering Value
These 10-24 UNC socket head cap screws are engineered to address critical fastening challenges in demanding sectors like machinery, automotive, and heavy equipment. The zinc-plated alloy steel material combats corrosion while maintaining Rockwell C37 hardness, preventing deformation under load. The partially threaded configuration and Class 3A thread fit provide exceptional grip and vibration resistance, crucial for dynamic applications where loosening could lead to equipment failure. With a coarse thread spacing and hex drive, they enable rapid installation and removal, streamlining assembly lines and reducing downtime. Ideal for high-stress joints, these screws deliver consistent performance where reliability is non-negotiable.
Specification Summary & Compliance
This socket head cap screw features a 10-24 UNC coarse thread with Class 3A fit for precise engagement, a 1-1/4" length with 3/4" minimum thread length, and a 5/32" hex drive. Manufactured to ASTM A574 specifications, it guarantees material and dimensional consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), meeting international environmental and safety standards for industrial use.
