If you’ve ever tried to undo or tighten a chainring bolt with a flat screwdriver slipping out the back, this is the fix. The PRO Chainring Nut Wrench is a steel chainring-nut holder with a long shaft for leverage plus 9 mm and 10 mm sockets, so it’s a handy little tool for home mechanics and shop benches alike.

The PRO Chainring Nut Wrench is built for one job that can quickly become frustrating without the right tool: holding slotted chainring nuts steady while you loosen or tighten the bolt from the other side. If your current method involves a screwdriver and a lot of slipping, this gives you a much more secure way to work on older-style chainring hardware.
Its long shaft gives you extra leverage, which helps when bolts are tight, overdone or just awkward to reach. The body is steel, so it suits regular workshop use, and the integrated 9 mm and 10 mm sockets add a bit of extra versatility for small fasteners around the bike.
This is the right pick if your crankset uses traditional slotted chainring nuts rather than newer hardware with hex fittings on both sides or direct-mount chainrings. It’s a simple, purpose-built tool, but when you need it, it saves time, reduces fuss and makes chainring changes much cleaner.
Ideal for home mechanics and riders maintaining bikes with traditional slotted chainring nuts who want the right tool instead of improvising with a screwdriver.
Made for slotted chainring nuts
Holds the back of a slotted chainring nut in place so you can tighten or loosen the bolt cleanly from the front.
Long shaft for leverage
The extended handle gives you more purchase, so stubborn or over-tightened hardware needs less hand force.
Steel construction
Built from steel for durability and repeated workshop use.
Integrated 9 mm and 10 mm sockets
Adds extra usefulness around the bike for small fasteners, rather than being a single-purpose tool only.
Better than a flat screwdriver
A dedicated fit helps reduce slipping compared with improvised tools, making chainring jobs less fiddly.
Useful for chainring swaps
Particularly handy when replacing chainrings, where the back nut can bind and spin with the bolt.
