S-91847A030 5/16"-18 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Space-saving thin profile (3/16" height) allows for use in tight assemblies where standard nuts are too bulky.
• Reliable and consistent thread engagement with Class 2B fit, ensuring smooth assembly and reducing the risk of cross-threading.
• Quick installation and removal with a standard 1/2" external hex drive, compatible with common wrenches and sockets.
• Robust performance in high-vibration settings due to the coarse 5/16"-18 UNC thread, which is less prone to loosening.
• Compliance with major environmental regulations including RoHS 3 and REACH, making it suitable for global supply chains and sensitive applications.
• Durable, long-lasting fastening with right-hand threading designed for standard rotational tightening in a wide range of machinery and equipment.

Professional Applications & Engineering Value
