A spinner spanner that fits all types of 2 eared & 3 eared Knock On spinner nuts including Borrani's, really for workshop use only as its quite large & heavy.

Note: During recent investigations the Knock On's only needs to be about 100 lbs ft torque or so, this is not as much as we thought & its very easy to overtighten the Knock Ons using the workshop spinner spanner.

Please see the Technical Section for information on how to fit Knock Ons properly.
