S-92220A172 10-32 x 3/8" ASTM A574 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies in critical applications.
• Low-profile socket head design allows for installation in confined spaces while maintaining high torque capability with a 3/32" hex drive.
• Fine UNF threads offer improved adjustment and holding power compared to coarse threads, ideal for precision equipment.
• Full threading along the 3/8" length ensures consistent engagement and clamping force across the entire fastener.
• Compliance with ASTM A574, RoHS 3, and REACH guarantees material consistency and environmental safety for global supply chains.

Professional Applications & Engineering Value

This 10-32 UNF low socket head cap screw is engineered to address common challenges in precision assembly, such as space constraints and vibration loosening. The black-oxide alloy steel construction, combined with a Rockwell C39 hardness, provides excellent durability and resistance to wear and corrosion, making it suitable for automotive, aerospace, and machinery applications. The fine thread Class 3A fit ensures minimal backlash and reliable performance in dynamic loads, while the low-profile head and hex drive facilitate easy installation with standard tools. Ideal for securing components in electronic enclosures, actuators, and other high-precision systems where reliability and compact design are critical.
