Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated alloy steel construction, extending service life in harsh industrial environments.
- Exceptional tensile strength of 170,000 PSI ensures reliable performance under high-stress conditions without failure.
- Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies in critical applications.
- Fine thread spacing and fully threaded design offer enhanced grip and uniform load distribution for improved joint integrity.
- Efficient torque transmission via the 5/32" hex drive and standard socket head, allowing for easy installation with standard tools.
- High hardness (Rockwell C37) reduces wear and deformation, maintaining dimensional stability over repeated use.
- Compliance with ASTM A574, RoHS 3, and REACH guarantees material quality and environmental safety for global supply chains.
Professional Applications & Engineering Value
This 10-32 UNF socket head cap screw is engineered to address common industrial challenges, such as vibration loosening and corrosion in machinery assemblies. The zinc-plated alloy steel material provides a durable barrier against moisture and chemicals, while the fine thread spacing and Class 3A thread fit ensure minimal backlash and secure fastening in precision equipment like automotive components, aerospace systems, and heavy-duty manufacturing tools. Its fully threaded design distributes stress evenly, reducing the risk of fatigue failure, and the hex drive allows for high-torque applications without slippage. Ideal for industrial fasteners requiring high strength and reliability, it supports efficient maintenance and long-term performance in demanding environments.
Specification Summary & Compliance
This product adheres to precise dimensional standards, including Class 3A thread fit for tight tolerances and UNF thread type with fine spacing. It meets ASTM A574 specifications for high-strength alloy steel screws and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for industrial use.
