S-94355A239 10-32 x 5/16" 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 thread engagement and vibration resistance due to the Class 3A UNF fine thread fit, ensuring a secure, reliable hold.
• High-strength, durable performance backed by a Rockwell B80 hardness rating, preventing stripping and deformation under load.
• Secure, flush-mount installation with a headless hex drive and flat tip, allowing for a clean finish and preventing snagging.
• Precise torque application enabled by the 3/32" hex drive, providing consistent clamping force without cam-out.
• Guaranteed dimensional accuracy and interchangeability through compliance with the rigorous ASME B18.3 standard.
• Safe for use in regulated industries as it is fully compliant with RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw is engineered to solve critical challenges in precision assembly and machinery. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it a reliable choice for applications in manufacturing, automotive, and electronics where environmental factors are a concern. The fine thread spacing and Class 3A thread fit offer a tighter tolerance than standard fits, which is crucial for applications demanding high vibration resistance and minimal backlash, such as in securing collars, gears, and pulleys onto shafts. The headless design with a hex drive allows for a flush installation, protecting the assembly from interference and providing a clean, professional appearance. This combination of precision engineering and durable materials ensures long-term performance and reliability in demanding industrial set screw applications.
