S-95345A482 6-32 x 3/4" ASME B18.13 Stainless Steel Pan Head Phillips Screws with External-Tooth Lock Washer

Key Features & Benefits at a Glance

• Superior vibration resistance with an integrated external-tooth lock washer that prevents loosening under dynamic loads, ensuring long-term joint integrity.
• Excellent corrosion resistance thanks to 18-8 stainless steel construction and passivated finish, ideal for harsh or outdoor industrial environments.
• High tensile strength of 70,000 psi provides reliable fastening for demanding applications, reducing the risk of mechanical failure.
• Effortless installation with a standard Phillips No. 2 drive and fully threaded UNC coarse thread design, speeding up assembly while minimizing cross-threading.
• Secure and stable locking from the 410 stainless steel washer, which maintains clamping force even under continuous vibration or thermal cycling.
• Broad compliance with industry standards, including ASME B18.13, RoHS 3, and REACH, ensuring safety and environmental responsibility in global supply chains.
• Versatile pan head profile offers a low-profile, rounded design that distributes load evenly and resists surface damage during tightening.

Professional Applications & Engineering Value

Engineered for reliability in industrial applications where vibration and corrosion are common challenges, these Phillips pan head screws integrate an external-tooth lock washer to eliminate the need for separate locking components. The 18-8 stainless steel material, combined with a passivated finish, resists oxidation and chemical exposure, making them suitable for machinery, electrical enclosures, and automotive assemblies. The coarse UNC threads and Class 2A thread fit ensure quick, precise engagement, reducing installation time and improving production efficiency. With a 70,000 psi tensile strength, they provide durable fastening that withstands mechanical stress, while the unified design simplifies inventory and reduces assembly errors in high-volume B2B settings.
