TOBWOLF 1 Pair 85A Roller Skates Toe Stops with 9/16" (14mm) Bolt, Durable Toe Stops Plugs, Round Shape Roller Skating Toe Stoppers Adjustable Rubber Brake Block Stoppers for Quad Skates

My Reidell skates have the Allen key on the side for tightening so the nut was not needed. The Allen Key would not tighten on the thread so I had to return it. It would probably be ok for regular skates that use the nut.

The brakes fit perfect on my roller skates and the price was great as well

Great Product!

Bought them to replace the stops on my Jackson Rave skates, they are actually better than the ones that came with them and handle the out door surfaces better. Glad I made the switch.
