3/4"-16 Grade 5 Hex Nuts
These MIDWEST FASTENER CORP hex nuts secure the threaded portion of machine screws and bolts. The pack contains 20 zinc-plated steel fasteners rated to Grade 5 strength. They suit automotive repairs, machinery assembly and general hardware tasks where a 3/4"-16 thread is required. Buyers needing a different thread pitch or a larger quantity per pack will not find it here.
Zinc-plated steel resists corrosion
The zinc plating protects the Grade 5 steel from rust during normal indoor or outdoor exposure. No special tools are needed beyond a standard wrench or socket that fits the hex head. Installation torque follows common Grade 5 guidelines for the 3/4"-16 size. These nuts are not intended for high-vibration environments that demand prevailing-torque or lock-nut designs.
Consistent clamping under sustained load
Grade 5 steel maintains its clamping force when bolts remain tightened for long periods in structural joints. The 20-piece count supports multiple connection points without reordering. Threads conform to the 3/4"-16 specification for reliable engagement with matching bolts. They are not suited for applications requiring stainless steel, higher-grade alloy strength or fine-thread variants.

Questions about this item
How do I install these 3/4"-16 Grade 5 hex nuts correctly?
Thread each nut onto a matching 3/4"-16 bolt or stud by hand until snug, then tighten with a wrench; the step people get wrong is skipping the hand-start, which can cross-thread the coarse 16 threads per inch.
What maintenance or replacement will these zinc-plated steel nuts need later?
Inspect the zinc plating periodically for white rust or red rust; replace any nut that shows corrosion, stripped threads, or deformation, because Grade 5 steel cannot be re-plated in place.
What limit appears first when these nuts are under sustained vibration or load?
The prevailing limit is loss of clamping force from vibration loosening; the plain hex design has no locking feature, so a separate lock washer or thread-locking compound is required for sustained dynamic loads.
