S-97042A176 1/4"-20 x 5" Partially Threaded Studs

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
• Reliable high-tensile performance with 70,000 psi tensile strength, ensuring secure fastening under load.
• Precise dimensional accuracy featuring ±0.005" shaft diameter tolerance for consistent fit and assembly.
• Optimized thread engagement with Class 2A thread fit and UNC coarse threading for quick, secure installation.
• Versatile partial threading design allowing flexibility in applications requiring both threaded and unthreaded sections.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.
• Right-hand threading for standard, intuitive installation in common mechanical systems.

Professional Applications & Engineering Value

This 1/4-20 UNC partially threaded stud in 18-8 Stainless Steel is engineered to address critical industrial challenges, such as corrosion in humid or chemical-exposed settings. Its Class 2A thread fit and coarse threading provide robust, vibration-resistant connections in machinery, construction, and automotive assemblies, reducing the risk of loosening. The partially threaded design allows the unthreaded shaft to act as a precision guide or spacer, minimizing misalignment in structural applications. With a 70,000 psi tensile strength, it supports heavy-duty fastening without compromising integrity, making it a reliable choice for engineers prioritizing durability and compliance with RoHS and REACH standards.

Specification Summary & Compliance

This stud adheres to UNC thread standards with a Class 2A thread fit for precise external threading. Dimensions include a 1/4"-20 thread size, 5" overall length, and 3/4" thread length, with shaft diameter tolerance of ±0.005". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
