Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Exceptional holding power provided by the cup point tip design, which bites into shafts for secure, vibration-resistant locking.
- High-precision thread fit (Class 3A) ensures tight tolerances and reliable engagement for critical assemblies.
- Easy installation and high torque capability with the internal hex drive (0.050"), allowing for secure tool engagement.
- Space-saving headless design enables flush mounting in applications where clearance is limited.
- Enhanced durability from Rockwell B80 hardness, providing good resistance to wear and deformation.
- Guaranteed compliance and quality with ASME B18.3 standards, RoHS 3, and REACH regulations for safe, industry-approved use.
Professional Applications & Engineering Value
This 4-48 UNF set screw is engineered to solve critical fastening challenges in precision assemblies. The 18-8 stainless steel material offers excellent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, or outdoor conditions. Its headless design and cup point tip provide secure, flush mounting and superior grip on shafts, pulleys, and gears, preventing slippage under vibration and dynamic loads. The fine UNF threads and Class 3A thread fit ensure precise engagement and reliable performance in high-stress environments like aerospace, automotive, and industrial machinery. With its hex drive for easy installation and high torque application, this set screw delivers consistent, long-lasting clamping force where precision and reliability are non-negotiable.
Specification Summary & Compliance
This set screw features a 4-48 UNF fine thread with a Class 3A thread fit for high precision, a length of 1/4", and a 0.050" hex drive. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental safety and industry-standard quality.
