S-94115A825 10-32 x 1/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Secure anti-loosening performance with durable green nylon 6/6 plastic tip that maintains grip under vibration and thermal cycling from -50° to 250°F
• Precise Class 3A thread fit ensures tighter tolerances and superior engagement in critical fine-thread applications
• Enhanced corrosion resistance through black-oxide coating on alloy steel, extending service life in demanding industrial environments
• Optimized torque transmission via 3/32" hex drive in headless design, allowing flush installation in confined spaces
• Consistent mechanical strength with Rockwell C28 hardness, providing reliable clamping force without deformation
• Broad regulatory compliance meeting ASME B18.3 specifications while being RoHS 3 and REACH compliant for global supply chain integration
• Right-hand UNF fine threading delivers superior resistance to vibrational loosening compared to coarse thread alternatives

Professional Applications & Engineering Value

This 10-32 UNF set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and positional accuracy are critical. The black-oxide alloy steel construction combined with Class 3A thread fit ensures minimal backlash in machinery components, while the nylon 6/6 plastic tip prevents surface damage to shafts and components without compromising clamping force. The headless hex drive design enables flush mounting in tight spaces commonly found in motor assemblies, precision instruments, and automated equipment. These industrial set screws solve common challenges of component slippage and thread wear in high-cycle applications, making them ideal for precision fastening in manufacturing, robotics, and aerospace assemblies where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 standards with Class 3A thread fit for superior dimensional accuracy in 10-32 UNF fine threading. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide alloy steel construction maintains Rockwell C28 hardness throughout the 1/4" length, while the 3/32" hex drive ensures consistent torque application. The nylon tip meets specified temperature range requirements from -50° to 250°F without performance degradation.
