Zerk Fittings Quality Control QC Hardness Testing (10 Samples)

Project Description

Mechanical Laboratory needed for zerk fittings quality control hardness testing. The print calls for a microhardness spec and the vendor claims in-spec according to the print.

We are having heavy fallout where the zerk fitting threads are ripping out during installation. I would like to get the hardness verified on a 10 sample lot
