Hex Jam Nuts Steel Zinc Plated 1/2-13 deliver secure, space-saving fastening for standard 1/2-13 bolted assemblies. Crafted from durable steel and finished with a corrosion-resistant zinc plating, these jam nuts resist rust and wear in everyday use.
Ideal for mechanical, automotive, and structural applications, a jam nut tightens against another nut or a surface to lock components in place. The hex shape provides easy wrench access and a low-profile stop that prevents loosening due to vibration.
How to use: Thread the jam nut onto the bolt until snug against the workpiece or another nut, then tighten to lock the assembly in place. This creates a compact, vibration-resistant joint with reduced risk of loosening over time.
