S-91375A245 10-24 x 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications.
• Superior corrosion resistance provided by the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• High-strength durability backed by Rockwell C45 hardness, ensuring the set screw maintains integrity under heavy loads.
• Easy installation and removal with a 3/32" hex drive, allowing for efficient assembly and maintenance with standard tools.
• Reliable positioning thanks to the cup tip design, which bites into surfaces to prevent components from slipping or loosening.
• Wide compatibility with UNC coarse threads and right-hand direction, making it ideal for common machinery and equipment.
• Regulatory peace of mind through compliance with RoHS 3, REACH, and ASME B18.3 standards, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

This 10-24 UNC set screw is engineered to address critical challenges in industrial fastening, such as component slippage and vibration-induced loosening. The black-oxide alloy steel construction offers enhanced corrosion resistance, which is vital for machinery exposed to moisture or chemicals. With a Class 3A thread fit and coarse UNC thread, it provides a precise, tight hold that reduces the need for frequent retightening in high-stress applications like automotive assemblies, conveyor systems, and heavy equipment. The cup tip ensures positive engagement with shafts or collars, preventing rotational movement and improving overall system reliability. Ideal for headless set screw uses where space is limited, this component delivers consistent performance in securing gears, pulleys, and other mechanical parts, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This set screw features a 10-24 UNC coarse thread with a Class 3A thread fit for high precision and minimal tolerance. It adheres to ASME B18.3 and ASTM F912 specifications, ensuring consistent manufacturing quality. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial applications.
