S-97042A111 3/8"-16 x 2 1/2" Partially Threaded Studs

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh environments and reducing long-term replacement costs.
• High-strength performance with a 70,000 psi tensile strength, ensuring reliable load-bearing capacity in critical assemblies.
• Precision dimensional control with a shaft diameter tolerance of ±0.001", guaranteeing consistent fit and simplified installation.
• Optimized thread engagement with a Class 2A thread fit, providing smooth assembly and reliable clamping force.
• Versatile partial threading design (3/4" thread length), offering both a secure threaded connection and a smooth shank for alignment or clearance.
• Broad compatibility with coarse 3/8"-16 UNC threads, making it a standard, readily available component for maintenance and manufacturing.
• Right-hand thread direction for intuitive, standard installation procedures, improving assembly efficiency.

Professional Applications & Engineering Value

This 3/8"-16 UNC partially threaded stud is engineered to solve common fastening challenges in industrial settings. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for applications in chemical processing, marine environments, and food-grade equipment where durability is critical. The Class 2A thread fit ensures consistent, reliable engagement with mating nuts, reducing the risk of cross-threading and assembly errors. The partially threaded design allows the smooth shank section to act as a precision pilot or spacer, while the threaded end secures the connection. This combination of high tensile strength (70,000 psi) and coarse UNC threading makes it an ideal choice for machinery, structural frames, and heavy-duty assemblies requiring a robust, corrosion-resistant fastener that withstands vibration and dynamic loads.

Specification Summary & Compliance

This stud adheres to UNC coarse thread standards with a Class 2A external thread fit, ensuring dimensional accuracy and interchangeability. The shaft diameter is manufactured to a tight tolerance of -0.001" to +0.001". The 18-8 stainless steel composition aligns with common industry specifications for corrosion-resistant fasteners. This product is compliant with RoHS and REACH environmental directives, making it suitable for use in regulated markets and applications requiring material safety and sustainability.
