Custom Stainless Steel Metric Male-Female Standoffs

 

These custom metric male/female standoffs were manufactured using 303 stainless steel material with commercial passivation.  M5 thread was tapped to a depth of 8MM and the male extension was machined without thread to a diameter of 3.8MM and length of 3MM.  The distance across the flats used for wrenching during the application was set to 7MM.

Custom Metric Hex Key Double Thread Studs

 

These custom metric hex key double thread studs were manufactured domestically for our automotive customer using alloy steel material meeting 220,000 psi clamp load minimum.  M12 thread was rolled on both sides, with fine pitch on the longer side and coarse on the other.  1/4" hex drive was formed on one side extending .25" from the fine threaded section.  Full certs were provided with the parts.

Custom Grade 5 Dacromet Coated Sheet Metal Screws

 

These custom Grade 5 #12 X 1-3/4" type AB sheet metal screws were manufactured to SAE J429 specifications with 25-34 core hardness, 120 KSI min tensile strength, and 92 KSI min yield strength.  Dacromet zinc flake coating was applied to complete the parts and a raised dot was incorporated to help our construction customer easily distinguish between these Grade 5 screws and the standard low carbon version also in use.

Custom Domestic Automotive Class 9.8 Hex Flange Bolts

 

These custom class 9.8 hex flange bolts were manufactured for our automotive customer in the USA.  M6-1.00 X 18MM thread was rolled and head dimensions were made to DIN 6921 specifications.  Parts were heat treated to 28-37 HRC core hardness per ISO 898-1 Class 9.8.  Level 3 PPAP and full certs were provided with the parts per customer requirements.

Custom AN316C8R Stainless Steel Jam Nuts

 

These custom AN316C8R jam nuts were manufactured domestically using DFARS compliant material to the AN316C8R specifications.  316 stainless steel hex bar stock was used for the production and parts went through NADCAP certified passivation per AMS QQ-P-35 with additional Proof Load lab testing per FF-N-836E to meet 12,000 lbf minimum criteria.  Full certs were provided with the parts per customer requirements.

Custom Inconel 718 Double Thread Offset Aerospace Bolts

 

Custom custom Inconel 718 double thread offset studs were manufactured for our aerospace customer.  The offset head, double thread, and hardness of material made these parts extremely difficult to manufacture.  The head radius measured .203" and a combination of 5/16-24 2A and 1/4-28 2A thread was cut to a length of .842".  Definitely one of the toughest parts we have dealt with - the hardness of the material created countless issues with tool life.  Full certs with FAIR were provided with the parts.

Custom M80 & M45 Large Automotive Flange Nuts

 

These custom M80 and M45 thread large flange nuts were manufactured for our EV automotive customer using Class 8.8 steel material with black phosphate finish.  180 degree nylon internal patch was applied to complete the parts per print.  Full certs and level III PPAP were provided with parts per our customer specifications.  

Custom 360 Brass Precision Machined Electronics Pins

 

These custom precision machined headed pins were manufactured using 360 Brass Alloy material per QQ-B-626.  Similar to the brass spacer in one of the prior posts this pin had a critical diameter dimension of .039" +0/-.002" for the extended pin.  The overall length of the part was set to .165" and the head height at .031, with both measurements being held to a +/-.002" tolerance.  Full certs were provided with the parts.

Custom Torx Drive 416 Stainless Flat Socket Head Gun Production Bolts

 

We provided our gun manufacturing customer these custom torx drive socket head bolts per print using 416 stainless steel material heat treated to HRC 36-44.  Approximately 13.8MM of 1/4-28 2A thread was rolled on both the 34.31MM and 43.61MM overall length version we had manufactured and the unthreaded shoulder diameter was set to 6.35MM +.00/-.22MM.  The head profile and countersink was customized to our customer's specifications.
