Well I got this cool tool but it has these spare parts and I didn't want to loose them. So I thought I would pass along this tip.
Here is what you do with the spare parts: pic 1
Well using a 7/16” drill bit, enlarge the existing hole, in the handle, drilling to the depth of 1 7/8”. Purchase a 7/16” vacuum cap/ wire end cap from Lowes or Home Depot and a 1.5 mm allen wrench. Cut the wrench to desired size. See pic 2
Now you have a storage place for all those loose parts; See pic 3
