-
Finish Options: Black oxide, plain, zinc-plated, or stainless
-
Grade: Typically Grade 8 (alloy steel), or 18-8 / 316 stainless steel for corrosion resistance
Key Features
-
Heavy-Duty Strength: Large thread diameter and high tensile strength make it ideal for extreme load-bearing applications.
-
Secure Thread Engagement: Precisely machined threads ensure strong and vibration-resistant fits with compatible 5/8"-11 tapped holes or standard heavy hex nuts.
-
Flush Mounting Design: The compact cylindrical head is ideal for counterbored installations where surface clearance is limited.
-
Efficient Torque Application: The internal hex socket reduces the risk of stripping and allows for precise torque control, even in deep-set or restricted spaces.
-
Corrosion-Resistant Options: Coated and stainless steel versions available for use in marine, chemical, or outdoor environments.
