Chrome Plated Phil Pan Hi-Lo Screws - 316 Stainless Steel Material With RoHS Compliant Tin Cobalt Finish, #10-16 X 3/4"

Another part to add to our growing list of custom tin cobalt and standard chrome plated fasteners.  These chrome plated phil pan hi-lo screws were manufactured overseas at approximately 50,000 pcs and supplied to our customer on a revolving blanket purchase order basis.  They measure #10-16 X 3/4" and are identical outside of the length to the #10-16 X 1/2 version we have supplied for a number of years already.  316 stainless steel material is used for optimal corrosion resistance, which is further enhanced with the chrome plating for use in highly corrosive environments.

Custom 316L Machined Hardware - 6MM X 1.0M Thread & Straight Nurl Application On The Nut

We had 100 pcs of this mating custom 316L machined hardware produced domestically with a lead time of approximately 4 weeks.  These 100 pcs were to be used in testing prior to larger volume production.  The rod pieces measures 90MM in overall length and the knurled nut measures 17MM in overall height.  Getting the nut fully tapped turned out to be the trickier part of the process - the taps kept breaking before the full depth was reached.  After a few adjustments and a change-up on the thread tap style used that last issue was finally resolved.  Material certs were provided with the parts per customer's original request.

Custom Stamped L Brackets - 3/4 X 3/4 X 3/4 In Steel Zinc At .125" Material Thickness

These custom stamped L brackets are made using low carbon steel material with zinc plated finish.  .125" thick material is used and the outside dimensions are 3/4" for each leg, as well as the width of the bracket length itself.  Production takes place in the USA and we typically run approximately 10,000 pcs at a time for this stamped part.  Our customer uses it in combination with two other custom stamped brackets used to assemble decorative paneling.

Custom Modified Truss Self Tapping Screws - #9 X 1-5/8 Type A Self Tapping Screws In 18-8 Stainless Steel

We have been selling these custom modified truss self tapping screws since 2004.  As of 2018 we supply this part in plain 18-8 stainless steel, black oxide finish shown here, satin sheen brown, and satin sheen grey shown below.

Custom Matte Painted Screws - 10-24 x 2 Inch Phil Pan Machine Screws In Different Version of Grey

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.

Differences In Thread Fit - 1A/2A/3A & 1B/2B/3B

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.

Custom Aluminum Cap Nuts - 3/8-16 Acorn Nut Manufactured Per Samples Provided

Our customer required matching custom aluminum cap nuts for renovation of a historical building and only had a few samples to work from without any dimensional drawings.  We used those samples to recreate the pictured replicas using plain aluminum material with 3/8-16 internal thread.  500 pieces were produced for our customer's need and were provided together with custom aluminum .403" X 1.38" fender washers at 2,000 pieces.

Custom Grade 5 Automotive Screws - Tricky 1/4-32 Thread With Nylon Thread Locking Patch

These custom grade 5 automotive screws are exactly the same dimensionally as the 1/4-28 version shown in one of the previous posts but with two specific distinctions: the thread had to be 1/4-32 instead for this 2,500 pcs batch and the lead time had to be FAST.  To accomplish this the hex socket drive was broached instead of cold heading, the marks of which you can see at the very bottom of the hex recess.  That allowed us to save weeks of lead time and we also expedited the thread lock application process as well as all the transit in between processes.  Level III PPAP paperwork is provided with the parts per our customers original request and requirement.

Custom Painted Screws In White - #6 X 1/2" 18-8 Stainless Steel Type A Sheet Metal Screws With Matching White Paint

Fresh out of the oven these custom painted screws in white are finished off with flat sealant to provide the matte white finish our customer desired.  We created a matching paint to paneling samples provided by our customer and ran approximately 20,000 pcs in this first run.  Parts are individually racked, spray painted, heat treated to ensure longevity, and then finished off with the sealant to adjust the gloss level.  Lead times depend on the quantities and type of paint used but we can typically turn around parts within 3 weeks or as fast as 3-4 days with an expedited option if we have the paint material in house.

Custom Stainless Steel Standoffs - M3 X 12MM X 4.15MM Across The Flats

Pictured here is one of the custom stainless steel standoffs we supply our drone manufacturing customer.  Production is done in the USA in 18-8 stainless steel material, with passivation as the final step in the production process.  Lead times vary depending on the quantity required and rush options are typically available upon request.  When usage volumes exceed 25K pieces or so we typically switch production to one of our overseas partners to optimize cost per piece.
