S-92311A412 3/4"-16 x 2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with fine thread spacing and Class 3A thread fit for precise, vibration-resistant fastening in demanding applications.
• Excellent corrosion resistance due to 18-8 Stainless Steel construction, ensuring long-term reliability in harsh or humid environments.
• High torque capability with the 3/8" hex drive, allowing for secure installation and removal without stripping, even under high stress.
• Enhanced durability and wear resistance from Rockwell B80 hardness, maintaining structural integrity over repeated use.
• Secure non-slip grip provided by the cup tip design, which digs into surfaces to prevent components from shifting or loosening.
• Space-saving headless design ideal for applications where a flush or low-profile finish is required without protruding parts.
• Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety, environmental responsibility, and consistent quality.

Professional Applications & Engineering Value

This 3/4"-16 UNF Class 3A set screw is engineered to address common industrial challenges such as component slippage, vibration-induced loosening, and corrosion in machinery. The fine thread spacing and Class 3A thread fit deliver exceptional clamping force and alignment accuracy, critical for precision assemblies in automotive, aerospace, and heavy equipment. Made from 18-8 Stainless Steel, it resists rust and chemical exposure, reducing maintenance costs. The headless design with hex drive allows for compact installations in tight spaces, while the cup tip ensures a firm bite on shafts or collars, preventing rotational movement. Ideal for securing gears, pulleys, and couplings, this screw enhances operational reliability and extends service life in industrial set screw applications.
