Key Features & Benefits at a Glance
- Vibration-resistant locking with permanent Nylon Patch thread locker, maintaining secure fastening from -70° to 250°F without loosening
- High corrosion resistance from 18-8 Stainless Steel construction, ideal for harsh industrial environments and extended service life
- Exceptional strength and durability with 70,000 psi tensile strength and Rockwell B55 hardness for heavy-duty mechanical loads
- Precise alignment and spacing through accurately machined shoulder (5/32" diameter, 1/4" length) for stable component positioning
- Reliable thread engagement with Class 2A UNC coarse threads ensuring consistent installation and reduced cross-threading risk
- Easy installation and removal using standard 3/32" hex drive socket head for efficient maintenance and assembly operations
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications
Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw with Nylon Patch thread locker addresses critical vibration-induced loosening in dynamic assemblies. The precision shoulder dimensions (5/32" diameter with -0.001" to 0" tolerance, 1/4" length with 0" to 0.002" tolerance) provide exact component alignment in machinery, robotics, and precision instruments. The UNC coarse threads with Class 2A fit enable rapid assembly while maintaining structural integrity under 70,000 psi tensile loads. Particularly valuable in automotive, aerospace, and electronic enclosures where thermal cycling (-70° to 250°F) and chemical exposure demand stainless steel's corrosion resistance combined with permanent vibration resistance.
Specification Summary & Compliance
Manufactured to exact Class 2A thread fit standards with UNC 6-32 coarse threading (0.138" diameter, 3/16" length). Shoulder specifications maintain precise tolerances: diameter 5/32" (-0.001" to 0"), length 1/4" (0" to 0.002"). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial fastener applications.
