These stand off are made using 303 stainless steel. We have found that a softer material is more durable than a hardened material.
The 4mm x 16mm set screws are made using 10.9 grade steel and are anchored with a 4 mm lock nut.
The set screws are JB WELDED IN PLACE TO ENSURE THAT THE SET SCREW DOESN'T BACK OUT.
These are replacement stand offs for the guys who have already purchased the m2c stand off kit. part no. 3080
