  • Custom 3 Wave Spring Washers

    This is a custom 3 wave steel spring washer that we have been supplying our customer for a number of years.  We stock an approximately 12-18 month supply of the part and release it throughout the year based on our customer's usage.  We can supply custom spring washers in a countless array of materials, sizes, and dimensional parameters.

  • Custom 316 Stainless Steel Socket Head Screws

    These are custom 316 stainless steel socket head cap screws at 10-32 X 1/2 and 10-32 X 3/8 in dimensions, manufactured domestically.  To allow for the small quantity and speed the hex socket drive was broached instead of using a cold headed approach.  You can see evidence of this at the inside of the recess drive where you would see machining marks instead of the typical clean concave interior seen in cold headed parts.

  • Custom A108 Steel U Bolts - ASTM A108 Material With Rolled 1/4-20 Thread

    These are custom A108 steel u bolts domestically manufactured with rolled thread. The picture shows the initial sample pieces made in plain ASTM A108 steel material for testing purposes, with the production order consisting of zinc plated version of the same part. The lead time for these custom round u bolts is slightly longer than usual, at 6-8 weeks from order confirmation. Material certs and cert. of conformance are available upon request and a rush order option is available if a similar u bolt is ever needed in a hurry.

    The inside width is set at 1.01-1.04", taking into account the drawn out material for the rolled thread. Inside depth is set at 1.84" and approximately .62" of thread is incorporated on each leg.

  • Custom Button Flange Socket Cap Screws - 8-32 X .50 In Grade 2 Steel With Nylon Patch

    These custom button flange socket cap screws were produced using grade 2 steel material with black oxide finish and nylon patch thread locking feature.  Full 8-32 thread was incorporated and the flange diameter was set at .357" +/-.005".  Head height including the flange was to be at .087" +/-.005" and a 3/32 socket drive was cold headed during the production process.  The blue nylon patch was applied over 180 degrees of the covered threaded section.

  • Custom Coil Compression Springs - Music Wire At .471" Outside Diameter

    These are one of the many custom coil compression springs we supply our agricultural equipment customer base, made in the USA using music wire and shipped with revolving 12 month blanket purchase orders. The outside diameter measures 0.471 inches, the free length is at 1.391 inches, and the custom springs maintain 9.4 coils.

  • Custom Flat Washer in 302 Series Stainless Steel

    This washer is a very similar part to the other narrow 304 stainless steel flat washer posted some days ago. It is made in the USA using 302 stainless steel in quantities of 1,000-1,500 pieces at a time and carries an approximate 4 week lead time. The dimensions are as follows: ID of .7180, OD of .9680, and Thickness of .0630.


  • Custom Knurled Shoulder Bolts - 41L40 Material With Zinc & Clear Finish

    These custom knurled shoulder bolts are the result of the tests we ran with different knurling methods mentioned in one of the previous posts. Parts came out perfectly but we did run into some challenges with the lead times, being behind initial expectations due to tooling delays early in the process. 41L40 material was used with heat treat and zinc plated finish. 1/4-20 thread is incorporated at 1" in length and the shoulder measures at 5/16 diameter by 1/2" in length. The head is at 3/16" in height and 9/16" in diameter.

  • Custom Long Stainless Steel Dowel Pins

    These custom long stainless steel dowel pins were manufacture domestically using 303 stainless steel material.  The diameter was set to 2.002mm to 2.008mm and the length was set to 100mm +/-.01mm.  Full certs were provided with the parts and thorough QC testing was done on the straightness.

  • Custom Metric Dacromet Coated U-Bolts - M4 X 52.07MM

    We had 1,100 pieces of these custom metric dacromet coated u-bolts produced using 42CrMo  material with heat treat hardening.  The part was originally designed to be made using 17-4PH stainless steel material but a number of attempts resulted in multiple failures during bending - the material was too hard and repeatedly snapped as the tool pressed the 90 degree corners.  As a result we switched to the 42CrMo material with heat treat to obtain the required hardness and strength, with a combination of the dacromet coating to achieve the corrosion resistance needed.  

  • Custom Metric Hex Head Fully Threaded Cap Screw in 410 Stainless Steel

    This is an M6 X 1.0 X 60MM hex head cap screw that is fully threaded per customer's specifications and manufactured in the United States using 410 stainless steel. Parts are then heat treated for required hardness. A similar part is supplied for the same customer at M5 diameter, which will be shown as a separate entry. Both parts are supplied on a one-time release basis at 5,000 pieces each.



  • Custom Metric Threaded Studs - M30 X 3.5M X 338MM In ANSI 1008 Material Plain

    These are custom metric threaded studs we supplied a customer in Orange County at 200 pieces.  They were manufactured domestically with a lead time of 2-3 weeks, made using ANSI 1008 material with material certs and chemical composition specs included.  ASME B1.13M-2005 M30X3.5M thread was required and the overall length for each stud was maintained at 338MM.  Our internal part number for this threaded stud is ATR-M30X35X388MM.

  • Custom Oval Point Set Screws In 18-8 Stainless Steel - 1/2-13 X 1"

    These are custom oval point set screws made domestically in the USA using 18-8 stainless steel material.  While this 1/2-13 X 1" size is fairly common off the shelf in a cup point version, the oval point is a tough find and typically requires a special production run.  We were able to get these set screws completed within 1 week at 100 pieces.  Material certs and our certificate of conformance was available with the parts.

  • Custom Phillips/Slotted Hex Washer Head Machine Screw

    This is a part we supply our long time customer on an as-needed basis every two years or so at approximately 40,000 pieces per order.  It is a M4-0.70 X 9.5MM phillips slotted combo drive hex washer head machine screw made using steel material with black oxide and light oil per customer specifications.  Made in the USA this part typically carries a 5-6 week lead time from order.

    These are custom socket shoulder screws made using grade 2 steel material with phos finish and a thread locking patch.  Measuring 6-32 X .393" with a shoulder at .080" and head height at .125" this custom socket shoulder screw is manufactured overseas in increments of 100,000 pieces to be released to our long time customer on an as-needed blanket purchase order basis.  Initial lead time for the first release is typically 120-150 days from order confirmation.  When needed, we can provide a print with dimensions and tolerances for the customer to approve prior to production start.

  • Modified Steel Coupling Nuts - 5/8-11 Internal Thread And 1" Across The Flats At 3.13" Overall Length

    Our customer requested these modified steel coupling nuts in plain steel finish and at just 56 pieces.  We began with an off-the-shelf coupling nut measuring 5/8-11 for the internal thread, 1" across the flats, and 3.13" in overall length.  Material was grade 5 plain steel.  Our customers drawing specifications required the internal cavity to be machined to a .65" diameter opening at 1" in depth for both sides, leaving approximately 1.13" of internal 5/8-11 thread in the middle for the mating part to engage.  Overall a relatively simple process completed within 1 week of order confirmation.
