Held in place by a socket head cap screw, this single shank metallic holder is made out of stainless steel.
These metallic holders are quite small in diameter. They will work well in applications where spacing is restricted.
Metallic holders are described by the Moly-D element size. As an example, the part description for a 3/6 Moly-D element is 3/6 Metallic Holder.
