S-95345A097 10-32 x 5/8" ASME B18.13 Stainless Steel Pan Head Phillips Screws with Internal-Tooth Lock Washer

Key Features & Benefits at a Glance

• Superior vibration resistance with an integrated 410 stainless steel internal-tooth lock washer that maintains clamp force under dynamic loads.
• Excellent corrosion resistance from 18-8 stainless steel construction and passivated finish, ideal for harsh or washdown environments.
• High-strength fastening with a tensile strength of 70,000 psi, providing reliable performance in demanding applications.
• Secure and precise installation using a standard No. 2 Phillips drive and Class 2A thread fit for consistent engagement and reduced cross-threading risk.
• Full thread engagement along the entire 5/8" length, ensuring maximum grip and load distribution in assembled components.
• Wide compatibility with 10-32 UNF fine threads, a common industrial standard for fine-adjustment and high-integrity assemblies.
• Regulatory peace of mind, manufactured to meet ASME B18.13 specifications and compliant with RoHS 3 and REACH environmental standards.

Professional Applications & Engineering Value

This 10-32 UNF rounded head screw is engineered to address critical challenges in industrial assembly, such as loosening from vibration and exposure to corrosive elements. The combination of 18-8 stainless steel and a passivated finish provides a durable barrier against rust and chemical degradation, making it suitable for machinery, electronic enclosures, and outdoor equipment. The integrated internal-tooth lock washer bites into both the screw head and mating surface, creating a prevailing torque that resists back-off in high-vibration environments like motors, conveyors, and automotive subsystems. With a fully threaded design and Class 2A thread fit, it ensures uniform stress distribution and ease of installation, reducing assembly time and improving joint reliability. These features make it an optimal choice for B2B procurement where long-term performance and compliance with industry standards are paramount.

Specification Summary & Compliance
