MIDWEST FASTENER 08212 Lock Nut
This MIDWEST FASTENER 08212 lock nut uses a nylon insert to resist loosening caused by vibration and torque. It is a Grade 8 steel fastener with a yellow finish, designed for demanding mechanical assemblies. The 3/4"-10 thread specification suits heavy-duty structural and automotive connections.
Suitable Applications and Limits
This nut suits maintenance crews, fabricators and automotive technicians who need a reliable prevailing-torque fastener for high-strength joints. It is not intended for applications that require a free-spinning nut, a different thread pitch or a non-metallic locking element. Buyers needing a jam nut, a flange nut or a larger diameter should look elsewhere.
Capacity and Headroom
The Grade 8 rating provides high proof load capacity for structural steel and heavy equipment mounts. The nylon insert maintains locking performance through repeated assembly cycles until the insert wears. Extreme temperatures or chemical exposure beyond the nylon's tolerance will reduce locking effectiveness.

Questions about this item
What size bolt does the 3/4"-10 thread on this lock nut fit?
The 3/4"-10 thread matches a 3/4" diameter bolt with 10 threads per inch.
Will the yellow zinc finish on this Grade 8 nut react with older plain-steel washers?
The yellow zinc coating is compatible with standard steel washers and does not cause galvanic corrosion in normal use.
How can I confirm the nylon insert is gripping properly after installation?
You should feel increasing resistance as the bolt engages the nylon insert, and the nut should not spin freely once fully seated.
