S-98057A487 10-24 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from 316 Stainless Steel construction, ideal for harsh environments and extended service life
• Reliable, secure fastening with Class 2A thread fit ensuring precise engagement and reduced risk of loosening under vibration
• Excellent mechanical strength provided by Rockwell B80 hardness, resisting deformation under high clamping loads
• Easy installation and adjustment with a standard slotted drive, compatible with common hand tools
• Effective point contact and minimal surface marring due to the cup tip design, protecting valuable components
• Broad compatibility with coarse UNC 10-24 threads, a common and readily available thread size in inch-system applications
• Confidence in regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for quality and environmental safety

Professional Applications & Engineering Value

This 10-24 UNC set screw is engineered to solve critical fastening challenges in demanding industrial settings. Manufactured from 316 Stainless Steel, it offers exceptional resistance to chemicals and chlorides, making it a top choice for marine, chemical processing, and food-grade equipment where corrosion is a primary concern. The headless, slotted design allows for a flush installation in tight spaces, while the coarse thread and Class 2A fit provide rapid assembly and a secure hold that resists vibrational loosening in machinery, pulleys, and gears. The cup tip concentrates clamping force for a firm grip without excessive surface damage. This combination of material properties and precision engineering delivers a reliable, long-lasting set screw that minimizes maintenance and downtime.

Specification Summary & Compliance

This set screw features a 10-24 UNC thread with a Class 2A tolerance for consistent, precise fit. The manufacturing and dimensional specifications conform to ASME B18.3. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and safe for use in regulated markets.
