S-92845A192 8-32 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for reliable, vibration-resistant fastening in demanding applications.
• Excellent corrosion resistance from 18-8 Stainless Steel construction, ideal for harsh or outdoor environments.
• Enhanced grip and alignment due to the extended tip design, preventing component slippage.
• Durable and long-lasting performance with a Rockwell B80 hardness, resisting wear and deformation.
• Secure and easy installation using a standard 5/64" hex key, providing a flush, headless finish.
• Wide industrial compatibility with UNC coarse threads and right-hand direction for common assembly needs.
• Regulatory peace of mind, meeting ASME B18.3 standards and being RoHS 3 & REACH compliant.

Professional Applications & Engineering Value

This 8-32 UNC set screw is engineered to address critical challenges in precision assembly and machinery. The 18-8 Stainless Steel material provides inherent resistance to rust and corrosion, making it suitable for applications exposed to moisture, chemicals, or varying temperatures. Its headless design and hex drive allow for a sleek, unobtrusive installation where space is limited, while the extended tip ensures a firm bite into the mating part, reducing the risk of loosening under vibration—common in motors, gears, and pulleys. The Class 3A thread fit offers tighter tolerances than standard fits, ensuring maximum thread engagement and holding strength for high-stress industrial environments. This combination of features makes it an ideal choice for OEMs and maintenance teams requiring reliable, long-term fastening solutions in automotive, aerospace, and manufacturing equipment.
