Custom Domestic Stainless Steel Wave Washers

 

These custom 3-wave washers were manufactured domestically in the USA using DFARS compliant 301 stainless steel material.  The outside diameter was set to 1.325" and the inside diameter to .975".  Raw material thickness was at 0.05" +/-.015.  Full certs were provided with the parts for our aerospace customer.

Custom Music Wire Torsion Springs

 

These custom torsion springs were manufactured using .090 diameter music wire material with .80-.95% carbon content and 230-399 ksi tensile strength.  Both legs measured 4.45" center to center with a 120 degree angle.  Zinc clear finish was applied to finish the parts for the architectural assembly application.

Custom Grade 5 Hex Coupling Nuts

 

These custom coupling nuts were manufactured using mild steel material with zinc clear finish.  1/2-13 thread was tapped all the way through the part at an overall length of 3/4".  5/8" across the flats bar stock was used to produce these parts.  

Custom Zinc Plated Flat Washers

 

These custom flat stamped washers were manufactured using low carbon steel material with zinc clear plated finish.  The washer outside diameter was set to .344" and the inside diameter to .210".  Thickness was designed to a .031" +/-.002" prior to the zinc plated finish.  

Custom Steel Slider Lock Pins With Cotter Pin

 

These custom machined steel post pins were manufactured using low carbon steel with plain finish.  The head measured .41" in diameter and the shoulder .200" with a .063 thru hole for the cotter pin.  The pins measured .60" in overall length underneath the head.  Cotter pin and washer used for the full assembly at application were also custom made to drawing for our electronics customer.

Custom Thin 10-32 Zinc Plated Hex Nuts

 

These custom hex nuts were manufactured using low carbon steel material per ASME B18.2.2 with zinc clear finish.  The thin height of the nuts were set to .094" +/- .005" and across the flats dimension to a 3/8" hex.  Standard chamfers were incorporated with light chamfer on both sides of the tapped holes.

Custom 1020 Steel Precision Machined Step Pins

 

These custom precision machined stepped pins were manufactured using 1020 steel material with the larger diameter set to .156" +/-.001 and the smaller diameter at .092" +/-.002.  The overall length measured 1.09" +/-.01 and the point incorporated a radius of R.078.  Material certs were provided with the parts per customer requirements.

Custom Alloy Steel Metric Cone Point Set Screws

 

These custom alloy steel metric cone point set screws were manufactured in alloy steel material with M12 - 1.75 rolled thread and 60MM length underneath the cold formed square head.  The square head measured 13MM X 13MM X 12MM in height.  The cone point incorporated a 9MM diameter shoulder to assist in assembly on the production floor.

Custom M3 X 0.5MM Stainless Steel Shoulder Socket Bolts

 

These custom stainless steel shoulder bolts were manufactured in 18-8 stainless steel material for our drone manufacturing customer.  M3 X 0.5MM thread was rolled with a thread relief machined below the 4MM X 5MM shoulder.  A 2MM hex drive was broached at the head and a precision machined profile was incorporated on the head to meet drawing requirements.
