S-92313A540 1/4"-20 x 3/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine, chemical, and outdoor applications.
• Exceptional holding power and vibration resistance from the Class 3A thread fit, ensuring a secure, precise, and reliable fastening connection.
• Easy installation and high torque capability with the 1/8" hex drive, allowing for efficient assembly using standard tools.
• Minimized component protrusion thanks to the headless design, perfect for applications with limited space.
• Enhanced grip and resistance to loosening provided by the cup point tip, which bites into the mating surface for a firm set.
• Durable, long-lasting performance ensured by a Rockwell B80 hardness, maintaining integrity under repeated stress.
• Broad compatibility and reliable performance with 1/4"-20 UNC coarse threading, designed for quick assembly and high-strength applications.

Professional Applications & Engineering Value

This 316 stainless steel set screw is engineered to solve critical challenges in demanding industrial settings. Its high corrosion resistance makes it a top choice for applications exposed to moisture, chemicals, and extreme temperatures, such as in marine hardware, chemical processing equipment, and food machinery. The headless design with a hex drive allows for flush mounting in confined spaces, preventing interference with moving parts. The UNC coarse thread and Class 3A fit provide a tight, secure connection that resists vibration-induced loosening, common in heavy machinery and automotive assemblies. Combined with the cup point tip, it ensures maximum grip on shafts and collars, enhancing the reliability of power transmission components and precision instruments. This screw delivers consistent performance, reducing maintenance needs and downtime in industrial set screw applications.
