Key Features & Benefits at a Glance
- Permanent vibration resistance with integrated nylon patch thread locker, ensuring secure fastening in high-motion environments
- Exceptional corrosion resistance from 18-8 stainless steel construction, providing long-term durability in harsh industrial conditions
- Precise alignment and positioning with controlled shoulder diameter tolerance (-0.001" to 0") for accurate component mounting
- Superior mechanical strength delivering 70,000 psi tensile strength and Rockwell B55 hardness for heavy-duty applications
- Wide temperature compatibility maintaining locking performance from -70° to 250°F across various operating environments
- Reliable thread engagement with Class 2A UNF fine threads ensuring consistent fit and reduced cross-threading risks
- Easy installation and removal through standard hex socket drive design requiring minimal clearance space
Professional Applications & Engineering Value
This precision shoulder screw with nylon patch locking technology addresses critical vibration-induced loosening in dynamic assemblies. The 18-8 stainless steel construction provides excellent corrosion resistance for manufacturing equipment, automotive components, and electronic enclosures exposed to moisture or chemicals. The 5/8" shoulder length with precise diameter control serves as an accurate pivot or spacer in rotating mechanisms, while the 10-32 UNF fine threads with Class 2A fit ensure reliable engagement in thin materials. The permanent thread locker eliminates the need for secondary locking components, streamlining assembly processes in automated production environments where maintenance access is limited.
Specification Summary & Compliance
Manufactured to exacting standards with Class 2A thread fit and precise shoulder diameter tolerance of -0.001" to 0". Features UNF thread standard with 10-32 fine thread specification and right-hand thread direction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The shoulder screw maintains dimensional stability with shoulder length tolerance of 0" to 0.002" for consistent performance in precision assemblies.
