S-92311A634 3/8"-24 x 1/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
• Exceptional holding power ensured by the Class 3A thread fit, providing a tight, secure, and vibration-resistant connection.
• Precise and secure installation with the hex drive and 3/16" drive size, allowing for high torque application without slippage.
• Enhanced grip and minimal surface damage from the cup tip design, which bites securely into the shaft for reliable positioning.
• Optimized for fine-adjustment applications due to the UNF fine thread (3/8"-24), offering greater precision in clamping force.
• Consistent mechanical strength with a Rockwell B80 hardness, providing reliable performance under load without deforming.
• Broad regulatory acceptance by meeting ASME B18.3 specifications and being RoHS 3 & REACH compliant for global industrial use.

Professional Applications & Engineering Value

This 18-8 stainless steel set screw is engineered to address critical challenges in precision assembly and motion control systems. The headless design and cup tip work in tandem to provide a flush, secure lock on shafts, collars, and gears, preventing axial movement in high-vibration environments like robotics, automotive, and conveyor systems. Its UNF fine threading and Class 3A fit ensure minimal backlash and superior clamping force, making it ideal for applications requiring exact positioning and repeatability. The hex drive facilitates easy installation in confined spaces, while the corrosion-resistant material guarantees longevity, reducing maintenance needs and downtime in demanding industrial applications.
