1/2-13 X 2-1/4 Inch Grade 8 Coarse Hex Cap Screws – Yellow Zinc Coated, 25-Piece For Heavy-Duty Fastening

About This Product

Need a bolt that can take a beating?
These Grade 8 coarse hex cap screws are exactly what you're looking for.

At 1/2 inch in diameter and 2-1/4 inches long, they're built for heavy-duty applications where lower-grade hardware just won't cut it.
The yellow zinc plating gives them a solid rust-resistant finish, so they hold up better than plain steel in damp or outdoor environments.

These screws are heat-treated and hardened, which is why they're rated Grade 8 – that's the tough stuff for automotive, farm equipment, industrial machinery, and structural projects.

The hex head takes a 3/4 inch wrench, so you can really crank down on them without stripping.
And the coarse thread (13 threads per inch) bites into materials fast, making installation quicker than fine-thread alternatives.

Each pack gives you 25 pieces, which is enough for a good-sized project or a bunch of smaller ones.

Just remember – these are serious fasteners for serious jobs.

Always double-check your application and don't use them for anything that requires a certified engineer's stamp if failure would be catastrophic.

But for general heavy-duty use?
These bolts are rock solid.

Dependable, tough, and built to last.
