S-93705A274 10-32 x 1 1/2" ASME B18.3 18-8 Stainless Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking: Integrated nylon patch thread locker prevents loosening under dynamic loads, maintaining clamp force in demanding environments.
• Superior corrosion resistance: Manufactured from 18-8 Stainless Steel for excellent durability and long service life in harsh or corrosive conditions.
• High-strength performance: With a 70,000 psi tensile strength and Rockwell B70 hardness, this screw reliably handles high-stress applications.
• Precise, secure fastening: Features a Class 3A thread fit and UNF fine thread for superior engagement and vibration resistance in precision assemblies.
• Wide operational temperature range: The nylon patch locker remains effective from -70° to 250° F, ensuring reliability across diverse thermal environments.
• Secure, flush installation: The standard socket head with a 5/32" hex drive allows for a low-profile installation and high torque application.
• Trusted standardization: Manufactured to ASME B18.3 specifications, ensuring dimensional consistency and interchangeability.

Professional Applications & Engineering Value

This 10-32 UNF Socket Head Cap Screw is engineered to solve critical challenges in industrial assembly and precision machinery. The combination of 18-8 Stainless Steel and a nylon patch thread locker directly addresses the dual problems of corrosion and vibration-induced loosening, common failure points in automotive, aerospace, and heavy equipment. The fine thread spacing and Class 3A thread fit provide a tighter, more precise engagement than coarse threads, making it ideal for applications on thinner materials or where adjustment sensitivity is crucial. Its partially threaded design concentrates the clamping force precisely where needed. This screw delivers predictable, long-term performance, reducing maintenance needs and preventing costly downtime in critical systems.

Specification Summary & Compliance

This screw conforms to the dimensional and mechanical requirements of ASME B18.3. The thread is a 10-32 UNF with a Class 3A fit for high precision. It is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for hazardous substances.
