S-92185A514 1/4"-20 x 5 1/2" Super-Corrosion-Resistant 316 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction and passivated finish, ideal for chemical, marine, and outdoor applications.
• Exceptional mechanical strength with a 70,000 psi tensile strength and Rockwell B70 hardness, ensuring reliable performance under high-stress conditions.
• Precise and secure fastening achieved with a Class 3A thread fit, minimizing the risk of loosening in critical assemblies.
• Easy installation and high torque capability provided by the standard hex socket drive and 3/16" drive size, allowing for efficient assembly in confined spaces.
• Versatile partial threading (1" min thread length on a 5 1/2" body) offers flexibility for applications requiring both clamped and unthreaded sections.
• Broad industry compliance with RoHS 3 and REACH regulations, ensuring environmental safety and suitability for regulated markets.
• Durable coarse UNC thread design resists stripping and allows for quicker installation compared to fine threads.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 316 Stainless Steel Socket Head Cap Screw delivers outstanding corrosion resistance, making it a top choice for applications in chemical processing, marine equipment, and food machinery where exposure to moisture and aggressive agents is common. The Class 3A thread fit and coarse UNC thread provide superior clamping force and vibration resistance, critical for maintaining integrity in dynamic assemblies. The hex socket drive enables high torque application in tight spaces, reducing installation time and improving reliability. With a partially threaded design, it allows precise positioning and is ideal for securing components that require a smooth shank. These features collectively address common engineering challenges like fastener failure, corrosion-induced degradation, and assembly inefficiency, ensuring long-term performance in heavy-duty industrial fastening.
