Allen Key Hex Key Hexagonal Key 8mm German DIN 911 Heavy Duty Tool Caterpillar
This listing is for a regular arm length 8mm Hex key. 
Arm length is approx 102mm. 
Overall length is 100mm. 
I have a set of Heavy Duty Allen Keys Hex Keys which came in a tool kit for a Caterpillar Excavator I purchased. 
Condition is new, none of them have ever been used
They have very minor surface scratches from having been left in tool bag with other tools.
I will be listing them all for sale and will combine postage to give the cheapest cost if you want more one. 
Sizes I still have for sale are 17mm, 10mm, 8mm, 6mm.
