S-92220A178 10-32 x 1 1/2" 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 in demanding applications.
• Corrosion-resistant black-oxide finish on alloy steel provides enhanced durability and protection against rust in harsh industrial environments.
• Precision Class 3A thread fit guarantees tight tolerances and secure fastening, minimizing vibration loosening and improving assembly reliability.
• Low-profile socket head design allows for installation in confined spaces where standard socket heads cannot fit, increasing design flexibility.
• Partially threaded shank enables precise clamping force distribution, ideal for applications requiring controlled grip length and reduced thread wear.
• Fine UNF thread spacing offers superior resistance to loosening under dynamic loads compared to coarse threads, enhancing long-term stability.
• Compliance with ASTM A574, RoHS 3, and REACH ensures adherence to rigorous quality and environmental standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

Engineered for precision and reliability, this 10-32 UNF low profile socket head cap screw in black-oxide alloy steel addresses common industrial challenges such as space constraints and corrosion. The low-profile head and fine thread spacing provide secure fastening in compact assemblies, like machinery enclosures and electronic housings, where vibration resistance is critical. With a Rockwell C39 hardness and high tensile strength, it withstands heavy loads and repetitive stress, reducing maintenance needs. The partially threaded design allows for optimal clamp load distribution, preventing joint failure in automotive, aerospace, and precision equipment applications. This fastener's compliance with industry standards ensures consistent performance and compatibility in global supply chains.
