S-93445A320 8-32 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 industrial environments
• Exceptional holding power from the cup point tip that bites into surfaces for secure, permanent fastening
• High-precision Class 3A thread fit ensures reliable engagement and vibration resistance in demanding applications
• Easy installation with hex drive using standard 5/64" tools, providing excellent torque transmission
• Enhanced locking capability through serrations that prevent loosening under dynamic loads
• Consistent performance backed by Rockwell B80 hardness for durability and repeated use
• Full regulatory compliance meeting ASME B18.3 standards with RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This 8-32 UNC set screw delivers critical engineering solutions where permanent positioning and vibration resistance are paramount. The 18-8 Stainless Steel construction provides excellent corrosion resistance for machinery, automotive, and outdoor equipment applications. The cup point tip creates permanent dimples in shaft surfaces, preventing axial movement in pulleys, gears, and collars. With coarse UNC threads and Class 3A fit, it maintains precise alignment in high-vibration environments while the hex drive design allows for high torque application without stripping. The combination of serrations locking and Rockwell B80 hardness ensures long-term reliability in industrial assembly operations.

Specification Summary & Compliance

This set screw features 8-32 UNC coarse threads with Class 3A precision tolerance for superior thread engagement. Manufacturing complies with ASME B18.3 specifications for dimensional accuracy and performance. The product is fully RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements, ensuring environmental responsibility and workplace safety standards.
