S-92695A786 3/8"-24 x 1 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Enhanced Durability & Corrosion Resistance: Crafted from Black-Oxide Alloy Steel with a Rockwell C45 hardness for long-lasting performance in demanding environments.
• Superior Fastening & Vibration Resistance: The 90° cone point bites deeply into materials, providing excellent grip and preventing components from loosening under stress.
• Precision Fit for Reliable Assembly: Class 3A UNF fine threads ensure a tighter, more precise fit compared to standard threads, minimizing the risk of cross-threading and failure.
• Streamlined Installation & Removal: The internal hex drive (3/16") allows for easy and secure installation with standard tools, even in confined spaces.
• Optimal for Flush & Compact Designs: The headless design sits completely within the assembly, creating a smooth, unobtrusive finish.
• Guaranteed Quality & Consistency: Manufactured to meet ASME B18.3 specifications, ensuring dimensional accuracy and reliable performance in every screw.
• Safe for Global Use: Compliant with RoHS 3 and REACH regulations, making them suitable for use in various international markets and applications.

Professional Applications & Engineering Value

This 3/8"-24 UNF set screw is engineered to solve critical challenges in industrial assembly and machinery. The Black-Oxide Alloy Steel construction provides a robust barrier against rust and wear, extending the component's life in harsh conditions. The combination of a fine thread (UNF) and a Class 3A fit delivers exceptional clamping force and vibration resistance, which is vital for securing gears, pulleys, and collars on shafts where precision alignment is non-negotiable. The 90° cone point concentrates pressure on a small area, creating a permanent locking point that prevents axial movement, making it ideal for high-torque applications. The headless, hex drive design is perfect for applications requiring a flush finish and tool access from the top, streamlining the assembly process in automotive, aerospace, and heavy equipment manufacturing.
