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 in demanding applications.
- Superior corrosion resistance from zinc plating protects against rust and environmental damage, extending service life in harsh industrial settings.
- Precise Class 3A thread fit guarantees tight, secure fastening with minimal backlash, ideal for applications requiring high vibration resistance.
- Fine UNF threading provides increased engagement and better load distribution compared to coarse threads, enhancing joint integrity.
- Fully threaded design allows for maximum adjustability and uniform clamping force along the entire length of the screw.
- Hex socket drive enables high torque application with reduced risk of cam-out, ensuring efficient installation in confined spaces.
- Rockwell C37 hardness offers excellent wear resistance, maintaining thread integrity through repeated assembly and disassembly cycles.
Professional Applications & Engineering Value
Engineered for precision assembly in industrial machinery, automotive systems, and electronic enclosures, these socket head cap screws address critical challenges in vibration-prone environments. The zinc-plated alloy steel construction provides essential corrosion protection while maintaining 170,000 PSI tensile strength for high-load applications. The 10-32 UNF fine thread configuration delivers superior resistance to loosening under dynamic loads, making these Class 3A threaded fasteners ideal for precision equipment where thread fit consistency is paramount. The combination of fully threaded design and hex drive allows for precise tension control in space-constrained assemblies, solving common installation accessibility issues while ensuring reliable long-term performance.
Specification Summary & Compliance
Manufactured to ASTM A574 specifications with Class 3A thread fit precision and UNF thread standards. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features right-hand thread direction and fully threaded rod type with consistent thread diameter of 0.19" and 3/16" length for dimensional accuracy across production batches.
