Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability
- Maximum holding power and vibration resistance due to the Class 3A thread fit, ensuring a secure, tight assembly
- Enhanced grip and component security from the extended tip design, which bites deeper into the mating surface
- High-strength durability with a Rockwell B80 hardness, providing excellent resistance to wear and deformation
- Reliable and standardized performance as it meets the stringent dimensional and quality requirements of ASME B18.3
- Easy installation and removal with a 3/16" hex drive, allowing for high torque application in confined spaces
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives
Professional Applications & Engineering Value
This 3/8"-16 UNC set screw is engineered to solve critical challenges in industrial assembly, where vibration loosening and component slippage can lead to equipment failure. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it suitable for applications in machinery, automotive, and outdoor equipment exposed to moisture. Its extended tip and coarse UNC thread create a powerful biting action into shafts, collars, and pulleys, ensuring a permanent, secure fit. The headless, hex drive design allows for flush mounting in space-constrained assemblies, while the Class 3A thread fit guarantees precise engagement for maximum clamping force and reliability in high-stress environments.
Specification Summary & Compliance
This set screw features a 3/8"-16 UNC coarse thread with a Class 3A thread fit for high precision. The extended tip has a length of 0.198" with specified tolerances. It is manufactured in compliance with ASME B18.3 standards and is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets strict environmental and safety regulations for industrial use.
