S-97149A427 1"-8 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide 18-8 Stainless Steel, ideal for harsh industrial environments and extending service life.
• Reliable thread engagement due to Class 2B fit, ensuring consistent clamping force and reducing the risk of loosening under vibration.
• Easy installation and removal with the standard external hex drive, allowing for high torque application using common tools.
• Enhanced durability in coarse thread applications as the 1"-8 UNC thread design resists cross-threading and speeds up assembly.
• Compliance with environmental regulations including RoHS 3 and REACH, making it safe for various global markets and applications.
• Optimal strength and dimensional stability from the standard hex nut profile (1-1/2" width, 55/64" height), providing a secure fit in heavy-duty assemblies.
• Right-hand thread direction for straightforward, conventional fastening in most mechanical systems.
