Product identity
These are Grade 8 steel lock nuts with a 1/2"-13 thread pitch and yellow zinc finish, supplied in a 50-piece pack. They suit mechanics, fabricators and maintenance teams who need high-strength fasteners that resist vibration loosening on heavy equipment, truck frames or structural steel assemblies.
Compatibility check
Verify that the mating bolts or studs are 1/2"-13 thread and that the application calls for Grade 8 strength before ordering. Confirm the yellow zinc coating meets your corrosion-resistance requirements and that a flange-style nut is acceptable where a standard hex nut was specified.
Build integration
The integrated flange distributes clamping force over a wider area, reducing surface damage and the need for separate flat washers. This simplifies the fastener stack and saves assembly time on high-vibration joints such as suspension mounts, engine brackets or trailer couplings.

Questions about this item
What comes in the 50351 pack and is anything else needed to use them?
The pack contains 50 lock nuts with a 1/2"-13 thread, Grade 8 steel and yellow zinc finish. No extra parts are required for installation.
How do I choose between the listed versions or capacities for this fastener?
Only one version is offered: 50 pieces of 1/2"-13 Grade 8 yellow zinc lock nuts. Select this pack when you need that exact quantity and specification.
What does the Grade 8 rating mean once the nut is installed in a real assembly?
Grade 8 indicates high tensile strength for heavy-duty clamping loads. The yellow zinc coating adds corrosion resistance, and the lock-nut design resists loosening under vibration.
