Key Features & Benefits at a Glance
- Superior tensile strength of 170,000 PSI ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical assemblies.
- Class 3A thread fit provides tighter tolerances for precise engagement, minimizing backlash and improving assembly accuracy in fine-thread applications.
- Zinc-plated alloy steel construction offers excellent corrosion resistance, extending service life in harsh industrial environments.
- Partially threaded design allows for secure clamping on specific sections, preventing over-tightening and distributing load effectively.
- Rockwell C37 hardness enhances wear resistance, maintaining thread integrity through repeated installations and removals.
- Hex socket drive (5/32") enables high-torque application with standard tools, facilitating quick and secure fastening in confined spaces.
- Compliance with ASTM A574, RoHS 3, and REACH ensures material consistency and environmental safety, meeting global regulatory standards for industrial use.
Professional Applications & Engineering Value
Engineered for demanding applications, these 10-32 UNF socket head cap screws address common challenges in machinery, automotive, and precision equipment assembly. The zinc-plated alloy steel material combats corrosion while the fine UNF threads and Class 3A fit deliver vibration resistance and secure fastening in dynamic loads. The partially threaded rod design focuses clamping force where needed, reducing stress concentration. Ideal for high-strength industrial fasteners requiring reliable performance, they ensure long-term durability and minimize maintenance downtime in critical systems.
Specification Summary & Compliance
This screw features a 10-32 UNF thread size with Class 3A thread fit for precise tolerance, adhering to ASTM A574 manufacturing standards. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety requirements are met for global industrial use.
