Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel material, ideal for harsh or marine environments where rust prevention is critical.
- High tensile strength of 70,000 psi ensures reliable load-bearing capacity and reduces the risk of fastener failure under stress.
- Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant connections in precision assemblies.
- Passivated finish enhances surface durability and further improves resistance to chemical and environmental degradation.
- Hex socket drive design allows for high-torque installation with standard 9/64" hex tools, minimizing cam-out and tool wear.
- Partially threaded shank offers flexibility for applications requiring clamping force on unthreaded sections.
- Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industry standards for hazardous substance restrictions.
Professional Applications & Engineering Value
This 8-32 UNC thread socket head cap screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress demands. Made from 316 stainless steel, it excels in aggressive environments—including chemical processing, marine, and food equipment—where passivated finish adds an extra layer of protection against oxidants and chlorides. The coarse UNC thread and Class 3A fit ensure quick assembly and secure fastening, reducing maintenance needs in machinery, automotive, and structural applications. Its partially threaded design allows precise clamping control, making it a versatile choice for assemblies requiring both alignment and tensile strength.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 3A thread fit for high precision. Dimensions include a 3" length, 8-32 thread size, 9/64" hex drive, and right-hand threading. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from restricted hazardous substances. Manufactured to deliver consistent performance with a tensile strength of 70,000 psi and Rockwell B70 hardness.
