Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction and passivated finish, ideal for harsh environments and extended service life
- High-strength performance offering 70,000 psi tensile strength and Rockwell B79 hardness for reliable load-bearing in demanding applications
- Precise component alignment ensured by the controlled shoulder diameter tolerance (-0.001" to 0") and precise shoulder fit
- Easy installation and removal with a hex socket drive (5/64") and standard right-hand UNC coarse threads
- Consistent thread engagement through Class 2A thread fit, reducing the risk of cross-threading and assembly errors
- Regulatory compliance assurance with RoHS 3 and REACH standards, meeting global environmental and safety requirements
- Versatile industrial suitability due to the 1/8" shoulder diameter and 5/32" thread length, accommodating various mounting and pivoting needs
Professional Applications & Engineering Value
This 4-40 UNC shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. Manufactured from 316 Stainless Steel with a passivated finish, it resists corrosion from chemicals, moisture, and high temperatures, making it suitable for industrial machinery, medical devices, and marine equipment. The hex socket head allows for secure torque application in confined spaces, while the Class 2A thread fit and precise shoulder dimensions ensure accurate positioning and reduced vibration. By providing a reliable pivot point or spacer, it enhances the longevity and performance of moving parts in demanding applications, minimizing maintenance downtime.
Specification Summary & Compliance
This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. Key specifications include a thread size of 4-40, shoulder diameter of 1/8" (tolerance: -0.001" to 0"), and thread length of 5/32". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability in industrial use.
