Fasteners Plus 5/8 in-11 x 18 in Type 304 Fully Threaded Rod

In this review the Fasteners Plus Type 304 stainless steel fully threaded rod is evaluated for contractors, fabricators, and anyone needing a reliable anchoring or hanging solution. The bottom line: this 5/8 in diameter, 18 in length rod delivers predictable strength and excellent corrosion resistance thanks to its Type 304 stainless steel construction, making it a solid choice for indoor and many outdoor uses where longevity matters.

Key Features

• Diameter and length: The 5/8 in diameter and 18 in length give a useful balance of stiffness and reach for common mechanical and structural tasks.
• Fully threaded: Threads run the full length of the rod so nuts and fasteners can be positioned anywhere along its span for flexible mounting and adjustment.
• Coarse 11 TPI threads: The 11 threads per inch coarse thread provides quick engagement for assembly and good holding power in standard nuts and fixtures.
• Cut threads from round stock: Threads are cut from full size round stock for consistent thread form and predictable fit with matched hardware.
• Type 304 stainless finish: The plain stainless finish offers strong corrosion resistance suitable for harsher environments compared with carbon steel options.

Who It's For

This rod is aimed at contractors, HVAC and sprinkler installers, and shop fabricators who need a reliable, fully threaded stud for hanging fixtures, pipes, lighting, or equipment support. Its multi-purpose nature makes it useful on job sites where customization and on-site adjustments are common.

Those who need specialized high-strength or marine-grade fasteners should look elsewhere; while Type 304 resists corrosion well, it is not a replacement for higher-alloy stainless grades required in highly corrosive saltwater exposures or extreme structural load cases.

Pros & Cons

Pros

• Good corrosion resistance from Type 304 stainless steel suitable for many outdoor and indoor applications.
• Fully threaded length allows flexible placement of nuts and fasteners for adjustments and mounting.
• Coarse 11 TPI threads provide fast assembly and broad compatibility with standard nuts.

Cons

• Type 304 is not the highest corrosion-grade for aggressive marine environments, so users in those conditions may prefer a different alloy.

Frequently Asked Questions

Is this rod suitable for outdoor use?
Yes; the Type 304 stainless steel offers good corrosion resistance for most outdoor and exposed applications, though not the highest protection for saltwater immersion.

Can nuts be placed anywhere along the rod?
Yes; because the rod is fully threaded, nuts and hardware can be positioned anywhere along its full 18 in length.

What thread pitch does it use?
It uses a coarse 11 threads per inch (5/8 in-11) thread form compatible with standard coarse nuts.
