- High thread reliability with Class 3A UNC coarse threads offering excellent engagement and vibration resistance.
- Compliance with industry standards including ASME B18.3, RoHS 3, and REACH for safe, quality-assured use.
- Durable and long-lasting with Rockwell B55 hardness, maintaining integrity under repetitive stress.
Professional Applications & Engineering Value
This 3/8"-16 UNC shoulder screw is engineered to address critical challenges in industrial assembly, such as misalignment and component wear. Made from 18-8 stainless steel, it resists rust and corrosion in demanding settings like machinery, automotive, and electronics. The 1/2" shoulder diameter provides a precise pivot or bearing surface, reducing friction and extending equipment life. With a hex socket drive and knurled head, it ensures quick, secure fastening even in tight spaces. Ideal for applications requiring high-strength fastening and repeatable accuracy, this screw minimizes downtime and maintenance costs while complying with rigorous standards.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit for tight tolerances and reliable engagement, adhering to ASME B18.3 specifications. The shoulder diameter tolerance ranges from -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", ensuring precision in assembly. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), supporting environmentally safe and regulated industrial use.
