Black 316 Stainless Steel Eye Bolt 1/4" | Extended Thread (2" & 4" Length)

Designed for professional rigging and post installations, our 1/4" Black T316 Stainless Steel Eye Bolts feature an Extended Thread Design. Unlike standard bolts with short threads, ours offer significantly longer threaded sections (2" and 4"), providing you with maximum flexibility for tension adjustments and secure nut locking on various post thicknesses.

Crafted from marine-grade T316 stainless steel with a sleek black finish, these bolts are perfect for cable railing systems, shade sails, and heavy-duty outdoor tie-downs where rust resistance is non-negotiable.

Key Features

  • Standard 1/4" Diameter: Features a standard 1/4"-20 UNC machine thread, compatible with most standard nuts and pre-tapped holes.
  • Extended Thread Length:
    • The 3" Model features a full 2-Inch Thread.
    • The 5" Model features a massive 4-Inch Thread.
    This extra length allows for greater tolerance when tightening nuts or passing through thick 4x4 posts.
  • Marine Grade T316 Core: Solid 316 Stainless Steel construction ensures the bolt remains rust-proof in saltwater environments, even if the black coating is scratched.
  • Complete Hardware Kit: Comes ready to install with matching Black Hex Nuts, Washers, and a Drill Bit.

Frequently Asked Questions

Q: What size nut fits this bolt?
A: This bolt uses a standard 1/4"-20 thread. The kit includes matching black nuts, but any standard 1/4"-20 nut will fit.

Q: Why is the extended thread length important?
A: A longer thread (2" or 4") gives you more room to tighten the nut. This is especially useful if your post thickness varies or if you need to apply significant tension to a cable railing system.

Q: Is the black finish durable?
A: Yes, it is a durable industrial coating. However, the core advantage is the T316 Stainless Steel underneath. Even in the unlikely event the finish is scratched during tightening, the bolt itself will not rust.
