Custom Deep Recess Phillips Drive Screws - #8 X 2" Phillips Pan Type A Sheet Metal Screws

At first glance these custom deep recess phillips drive screws seem like ordinary sheet metal screws.  For the most part that is true - the Type A thread and head dimensions are essentially per IFI specs without any modifications.  A closer look however will reveal a significantly deeper recess in the phillips drive.  Standard #8 phillips drive for a pan head reaches a depth of .108" while this custom part has a recess depth of .120" to .122" - a significant difference when it comes to improved engagement and faster/easier use on the production floor.  This improvement in speed and engagement was the main driver behind our customer's request for this modified sheet metal screw, particularly important when some of the depth is used for paint when the screw heads are painted a variety of different colors.

Custom Metric 316L Set Screws - M5-0.8 X 6MM Short Dog Point Socket Set Screws

We ran an order of these custom metric 316L set screws with a short dog point at just 66 pieces using domestic production.  Lead time was relatively short at just 2-3 weeks from confirmed purchase order receipt.  A short .059 dog point was incorporated and a 2.5MM hex socket drive was broached for speed and cost efficiency.  Overall length was set at 2.36 inches and the tolerance on all dimensions was set at +/- .005 inches.  Great detail can be seen in the print included here as a reference.

Orange Painted Sheet Metal Screws - #8 X 3/4" in 18-8 Stainless Steel

These orange painted sheet metal screws are one of the brighter and more colorful painted screws we supply our customer base.  Most of the painted screws are in more subdued varieties of white, grey, and brown to match a variety of paneling used by our customers in their respective assembly lines.  The base screw itself is a standard off the shelf 18-8 stainless steel #8 X 3/4" type A sheet metal screw.  Lead time for this color is similar to the others at 2-3 weeks from order confirmation but an expedited processing option is typically available upon request.

Custom A286 MS24693 Screws - Phil Flat 4-40 X 1/4"

These custom A286 MS24693 screws can look deceivingly simple at first glance.  The A286 material was a large deviation from the typical MS24693 specifications and the parts had to be heat treated to 140 KSI.  To finish off the production process the parts went through a NADCAP certified sand blast and descale & passivation process per AMS2700  Type 2 Class 1.  The production consisted of approximately 50,000 pcs and was completed domestically.  NACAP cert for the passivation was provided together with material cert and certificate of conformance.

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.
