- High tensile strength of 70,000 psi ensures secure, vibration-resistant fastening in demanding applications.
- Precise Class 3A thread fit guarantees consistent engagement and reduces the risk of cross-threading during assembly.
- Hex socket drive (3/32") allows for high-torque installation and removal in confined spaces.
- Partially threaded design provides optimal clamping force and prevents thread damage in non-threaded sections.
- Rockwell B70 hardness offers excellent wear resistance and durability under mechanical stress.
- Compliance with ASME B18.3, RoHS 3, and REACH ensures adherence to industry standards and environmental regulations.
Professional Applications & Engineering Value
This 5-40 UNC Socket Head Cap Screw in 18-8 Stainless Steel is engineered to address critical industrial fastening challenges, such as corrosion in humid or chemical-exposed settings. The coarse thread design facilitates quick assembly and reduces the risk of stripping in softer materials, while the hex drive enables efficient torque application in tight spaces common in machinery and equipment manufacturing. With a 1-1/4" length and partially threaded profile, it delivers reliable clamping in applications like automotive components, electronic enclosures, and precision instruments, ensuring vibration resistance and long-term structural integrity. The high tensile strength and Rockwell B70 hardness further enhance its performance in high-stress environments, minimizing maintenance needs and downtime.
Specification Summary & Compliance
This screw adheres to ASME B18.3 standards, with precise Class 3A thread fit and UNC coarse threads for consistent performance. It is manufactured in the inch system with a length of 1-1/4" and meets regulatory requirements including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring safety and environmental responsibility.
