These are 3 different custom matte painted screws we supply our long time customer - different shades of grey with one (on the right) incorporating metallic flake features with a darker overall look. All three colors were finished with a flat sheen clear coat to create the matte final result. This clear coat process was the trickiest part of the process as each color changed differently once that final coating was applied - often requiring a drastic reformulation of the base color to anticipate the adjustments that will take place. Thankfully, once this initial manipulation is completed the results can be easily replication on subsequent orders.

Thread fit measures the looseness of fit between male and female threads. For external threads the three fit classes are 1A/2A/3A and for internal thread (for example in hex nuts) 1B/2B/3B. The higher the class number the tighter the fit - 3A/3B fit therefore is the tightest and presents the greatest risk when the parts require any type of plating or additive finish. In our experience parts that require 3A/3B thread fit are at greater risk of not passing the Go/No-Go gauge test after electroplating, especially at smaller diameters. Typically this happens because more of the plating material is added to the part at it's extremities, making a consistent plating thickness difficult to achieve and thereby compromising the tight fit tolerance at the end of the screw where the gauges engage.
