Professional Applications & Engineering Value
This 316 stainless steel pan head slotted screw delivers critical performance advantages in demanding industrial settings where corrosion resistance and mechanical reliability are paramount. The combination of UNC coarse threading and Class 2A thread fit ensures rapid installation with minimal cross-threading risk, while the passivated finish significantly enhances the natural corrosion resistance of 316 stainless steel against chlorides, acids, and industrial chemicals. Engineers specify these rounded head screws for chemical processing equipment, marine hardware, food processing machinery, and pharmaceutical applications where both regulatory compliance and long-term performance are essential. The slotted drive style maintains compatibility with standard installation tools while providing reliable torque transmission in space-constrained assemblies.
Specification Summary & Compliance
Manufactured to exacting dimensional standards with Class 2A thread fit tolerance and UNC coarse threading (1/4"-20). Fully compliant with ASME B18.6.3 mechanical and dimensional specifications. Meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) requirements. The 3/8" length and fully threaded design ensure consistent performance across the specified application range.
