S-92695A686 5/8"-11 x 1" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with a 90° cone point that bites into materials for secure, permanent positioning in high-vibration environments.
• Superior corrosion resistance from the Black-Oxide finish on Alloy Steel, extending service life in demanding industrial conditions.
• High-strength durability backed by a Rockwell C45 hardness, ensuring the screw withstands high torque and resists wear over time.
• Precise and reliable fit with a Class 3A thread fit, providing tighter tolerances for secure fastening in critical applications.
• Easy installation and removal using a standard 5/16" hex key, allowing for efficient assembly and maintenance with common tools.
• Versatile coarse UNC threading (5/8"-11) enables quick installation and robust performance in a wide range of materials.
• Space-saving headless design allows for flush mounting where protruding fastener heads are not feasible.

Professional Applications & Engineering Value

This 5/8"-11 UNC set screw is engineered to solve critical challenges in industrial assembly, such as component slippage and misalignment under stress. The Black-Oxide Alloy Steel construction provides a tough, corrosion-resistant base, while the 90° cone point concentrates force to create a permanent, non-slip grip on shafts, collars, and gears. Its Class 3A thread fit and coarse thread design ensure rapid installation and high resistance to loosening in heavy machinery, automotive systems, and power transmission equipment. By combining high Rockwell C45 hardness with a headless, hex drive configuration, it delivers reliable performance in confined spaces, reducing maintenance needs and enhancing operational safety in demanding engineering environments.
