S-92991A119 10-24 x 3/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Corrosion-resistant brass construction ensures long-term reliability in demanding environments, reducing maintenance needs and replacement costs.
• Precise Class 3A thread fit provides superior engagement and vibration resistance, minimizing the risk of loosening in critical assemblies.
• Rockwell B55 hardness offers excellent durability and wear resistance, maintaining thread integrity through repeated installations.
• Compact 3/32" hex drive and headless design allows for installation in tight spaces and provides a flush, unobtrusive finish.
• Cup point tip creates a strong bite into the shaft material, ensuring a secure and non-slip grip for permanent positioning.
• Compliance with ASME B18.3, RoHS 3, and REACH guarantees consistent quality, safety, and environmental responsibility for global supply chains.
• 10-24 UNC coarse thread enables faster installation and is less prone to clogging with debris compared to fine threads.

Professional Applications & Engineering Value

This 10-24 UNC brass set screw is engineered to solve common industrial challenges like corrosion, vibration loosening, and space constraints. The brass material inherently resists rust and galvanic corrosion, making it ideal for use in electrical components, marine hardware, and plumbing systems where moisture is a concern. The headless design with a hex drive is perfect for securing collars, gears, and pulleys on shafts without protruding, preventing interference in compact machinery. The Class 3A thread fit and cup point tip work in tandem to provide a vibration-resistant lock that maintains precise alignment in high-stress applications, from motor assemblies to precision instruments. This combination of material properties and mechanical design delivers reliable, long-lasting fastening for industrial set screws requirements.
