Key Features & Benefits at a Glance
- Vibration-resistant locking with permanent nylon patch to prevent loosening under dynamic loads, ensuring reliable performance in demanding environments.
- Exceptional corrosion resistance from 18-8 stainless steel construction, ideal for harsh or moisture-prone industrial settings.
- High tensile strength of 100,000 psi provides superior load-bearing capacity for critical structural and machinery applications.
- Precise Class 3A UNF fine thread fit delivers secure, accurate engagement with mating components, reducing the risk of cross-threading.
- Wide temperature tolerance from -70° to 250°F for the thread locker and -40° to 225°F for the optional Buna-N O-ring, suitable for extreme operating conditions.
- Hex socket drive design allows for high-torque installation in confined spaces, enhancing assembly efficiency.
- Compliance with ASME B18.3 and environmental standards ensures consistent quality and safe use in regulated industries.
Professional Applications & Engineering Value
This 18-8 stainless steel socket head cap screw is engineered to address common industrial challenges such as vibration-induced fastener failure and corrosion. The nylon patch locking mechanism provides a permanent, chemical-free thread-locking solution that maintains integrity across a broad temperature range (-70° to 250°F), making it ideal for heavy machinery, automotive assemblies, and precision equipment. Combined with Class 3A UNF fine threads, it ensures tight, reliable fastening in high-pressure applications up to 1500 psi, while the corrosion-resistant material and Buna-N rubber O-ring option offer extended service life in aggressive environments. Its hex drive and socket head facilitate easy installation in tight spaces, streamlining maintenance and reducing downtime.
Specification Summary & Compliance
This fastener features a 5/16"-24 UNF fine thread with Class 3A fit for precise tolerance, a 1" length, and is manufactured in accordance with ASME B18.3 specifications. It is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting stringent environmental and safety standards for industrial use.
