Product Identity
These Grade 8 steel hex nuts feature a 7/16"-20 thread pitch and a zinc yellow finish for corrosion resistance. The 25-piece pack suits automotive repair, machinery maintenance and general fastening tasks where high tensile strength is required.
Compatibility Check
Verify that the mating bolt or stud uses a 7/16"-20 thread before ordering. Confirm the application demands Grade 8 strength rather than a lower grade and that the zinc yellow coating meets the project's corrosion-protection needs.
Sustained Load Behaviour
Grade 8 steel maintains clamping force under continuous vibration and heavy static loads without stretching. The zinc yellow plating resists oxidation during extended exposure to moisture and road salt, preserving thread integrity over long service intervals.

Questions about this item
Does the 25 pack include washers or lock washers, or are they sold separately?
The pack contains 25 hex nuts only. Washers and lock washers are not included and must be purchased separately.
Which thread specification matches a 7/16"-20 bolt — coarse or fine?
The 20 threads per inch indicate a fine-thread UNF pattern, so these nuts match 7/16"-20 bolts, not coarse-thread versions.
What clamping force can a Grade 8 nut with zinc yellow finish deliver on a 7/16" bolt?
Grade 8 steel provides high tensile strength for heavy-duty clamping, while the zinc yellow coating adds corrosion resistance for automotive and industrial use.
