S-92505A640 10-32 x 3/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in critical assemblies
• Extended tip design ensures deeper penetration and secure locking, preventing component slippage under dynamic loads
• Exceptional durability from Rockwell C45 hardened alloy steel, providing high shear and tensile strength for demanding industrial environments
• Corrosion-resistant black oxide finish enhances longevity and performance in harsh operating conditions
• Hex drive compatibility with 3/32" tools allows for high-torque installation and easy maintenance access in confined spaces
• Fine thread spacing delivers improved load distribution and reduced risk of loosening in precision machinery
• Headless construction enables flush mounting for streamlined assemblies and rotating components

Professional Applications & Engineering Value

Engineered for maximum reliability in industrial settings, these 10-32 UNF set screws address common challenges like vibration-induced loosening and alignment shifts. The Black Oxide Alloy Steel construction combined with Rockwell C45 hardness ensures consistent performance under high stress, while the extended tip provides enhanced grip on shafts, collars, and pulleys. Ideal for precision equipment, automotive components, and machinery requiring fine thread spacing and right-hand thread configurations, these screws deliver secure fastening in applications where space constraints and operational integrity are critical.
