Key Features & Benefits at a Glance
- Vibration-resistant locking with permanent nylon patch prevents loosening in demanding applications, ensuring long-term assembly integrity.
- Superior corrosion resistance from 316 stainless steel construction, ideal for harsh environments like marine or chemical processing.
- High tensile strength of 70,000 psi provides reliable load-bearing capacity for critical mechanical connections.
- Precise Class 3A thread fit ensures smooth installation and secure fastening with minimal risk of cross-threading.
- Wide temperature tolerance (-70° to 250°F) maintains performance in extreme thermal conditions without degradation.
- Hex socket drive design allows for high-torque installation in confined spaces with standard tools.
- Full regulatory compliance with ASME B18.3, RoHS, and REACH standards guarantees quality and environmental safety.
Professional Applications & Engineering Value
Engineered for precision assemblies requiring vibration resistance and corrosion protection, these 316 stainless steel socket head cap screws with UNC coarse threads deliver exceptional performance in machinery, aerospace, and marine equipment. The nylon patch thread locker eliminates the need for separate locking washers or adhesives, reducing assembly time while preventing spontaneous loosening under dynamic loads. With Rockwell B70 hardness and 70,000 psi tensile strength, they withstand high-stress applications where fastener failure is not an option. The hex drive and standard socket head profile facilitate quick installation in tight spaces, making them ideal for maintenance-critical industrial systems.
Specification Summary & Compliance
This 4-40 UNC thread socket head cap screw features Class 3A thread fit for precision tolerance, coarse thread spacing for rapid installation, and fully threaded design. Manufactured to ASME B18.3 specifications with compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Dimensions include 1/4" length, 3/32" hex drive, and right-hand thread direction.
