Big grip. Big torque. Zero tools.

Stop fumbling with slick, undersized hardware every time you rearrange your rack. The Afterburn Nut is an oversized (3in diameter), aggressively knurled hand nut built for one thing: getting attachments on and off fast. Most hand nuts give you two or three fingers of grip — the Afterburn's extra-wide, extra-deep body lets you wrap your entire hand around it and put real torque into every turn. Snug it down tight, break it loose easy, and get back to lifting.

At its core is a genuine steel nut, fully embedded inside the body — your hand does the turning, but steel threads do the holding, so your attachments stay locked down and secure.

When it's not on a bolt, it doesn't belong in a drawer. Built-in high-strength magnets let you stick the Afterburn right onto your uprights or crossmembers, so your hardware stays exactly where you'll need it next.

The crack-proof, scratch-proof body is easy on your gear — no chewed-up threads, no scuffed powder coat — while the knurled black finish and your choice of accent color make it look like it came standard on a rack twice the price.

A premium nut for a premium lifter.

Why Afterburn

  • Oversized knurled body — full-hand grip for serious torque, no wrench required
  • Steel nut fully embedded inside for a secure, reliable hold on your attachments
  • Strong integrated magnets for instant storage on your uprights or crossmembers
  • Crack-proof, scratch-resistant construction that protects your hardware and your rack's finish
  • Jet-black body with 12 customizable accent colors

Compatibility

  • Choose your hardware size at checkout: 1-Inch, M24, 5/8-Inch, or M16
  • Magnets require a steel surface — NOT compatible with stainless steel racks (the threads still fit; the magnets won't hold)
  • IMPORTANT: Threaded portion beyond the nut must be less than 7/8in to be compatible (.875in or 22mm)

Sizing & compatibility

Every FrogFits accessory is made for your rack's hardware size — 5/8-Inch, 1-Inch, M16 or M24. Measure the bolt that holds your rack together, or check your rack manufacturer's specs. Common examples: Rogue Monster Lite = 5/8-Inch, Rogue Monster = 1-Inch, REP PR-4000 = M16, REP PR-5000 = M24. Product-specific notes are in the description above.

Questions & answers

Ask a question
Can hand-tightening really hold my attachments?

Yes — your hand does the turning, but a genuine steel nut embedded in the core does the holding. The 3in knurled body just lets you put real torque into it.

Where does it go when it's off the bolt?

Stick it right on your uprights or crossmembers — built-in high-strength magnets keep your hardware where you'll need it next.

Which size do I need?

It comes in 1-Inch, M24, 5/8-Inch and M16 — check the Sizing & compatibility guide on this page if you're not sure which your rack runs.
