-
These parts are manufactured overseas and supplied to our customer on a blanket as-released purchase order basis. We originally supplied this 10 X 1/2 phil pan hi-lo in plain 316 stainless steel material but at some point our customer needed additional corrosion resistance in their application. At that point we had our inventory supply barrel plated to the pictured chrome finish and all future imported parts would come in already chrome plated. Domestic chrome finish, whether barrel plated or individually racked, typically has a much brighter finish than the finish found on large volume imported parts.
-
This is a custom hex jack screw (male/female standoff) manufactured in the United States, with full dimensions at 4/40 X 3/16. The parts were made using steel material with nickel plating, as well as nylon patch application per customer's drawing specifications.

These are 18-8 stainless steel knurled pins made to an electronics customer's print. They measure approximately .800" in length at a diameter of .118". Of-course the only tricky requirement is the diamond knurling of .150" at each side that is intended to bite into the plastic setting. In order to increase the diameter at the knurled ends and allow for better locking into the plastic the factory adjusted their method to allow for very aggressive knurling, thereby pushing the material further and increasing the overall diameter at both sides.
-
These are custom double end studs made using 303 stainless steel (18-8 stainless steel) for our electronics manufacturing customer. Domestically made at approximately 4,000 pcs these parts were made to the drawing shown below with AA1096 microspheres thread locking feature one the shorter threaded end. 1/4-20 thread was incorporated on the long threaded portion, while 10-24 was used for the shorter end with the thread lock patch. A #2 square drive was broached on the 1/4-20 side as well.
-
These are the more unusual u bolts we have supplied over the years - they are custom fully threaded u bolts.

Our customer used these custom screws in their electronics assembly process.
-
We supplied these custom length shoulder bolts to our audio device manufacturer. The shoulder bolt is essentially an off-the-shelf 1/4 X 1 shoulder bolt with 10-24 rolled thread in 18-8 stainless steel material. Our customer was unable to use this version as-is due to the combined length of threaded portion and the machined fillet preceding it. In order to make use these parts that combined length had to be at .24" +/- .01". As a relatively simple operation we ran these parts through a cut and chamfer operation to get them to the correct length. Lead time for this operation was 1-2 weeks from receipt of the off-the-shelf version.
