Custom 316 Stainless Sealing Washers - Neoprene Bonded Sealing Washers In 316 Stainless Steel Material

We supply these custom 316 stainless sealing washers on a recurring blanket purchase order basis.  They measure 7/8" on the inside diameter, 1-1/2" on the outside diameter, and an overall nominal thickness of .101".  Dimensionally this sealing washer is relatively common in the market but only in 18-8 stainless steel or steel zinc material.  Our customer's application required the use of 316 stainless steel, which necessitated the custom production run.   We typically run production at 12,000 piece increments and release partials to our customer on an as-needed basis over the 12 month blanket period.

Custom Titanium Dowel Pins - 1/16 X 1/4 OAL

These custom titanium dowel pins were manufactured domestically using ASTM B348 Grade 5 material.  Our customer was a US University based physics research facility and per their request a material certificate with a certificate of conformance was provided with the parts.  The 1/16 diameter had a tolerance of +/- .005.

Custom Vented Screws In Invar 36 Material - 8-32 X 5/8 And 6-32 X 1/4

Both of these custom vented screws are recurring parts for a research lab we work with.  Measuring 8-32 X 5/8 and 6-32 X 1/4 both are made using Invar 36 material with a vent drilled hole running the full length of the screw.  Invar 36 material has a very low level of thermal expansion and is typically used for applications where dimensional changes due to temperature variation must be minimized as much as possible.  The hex socket drive was broached for both parts, in lieu of a cold headed alternative.

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.

Custom V Bolts In Steel Zinc Material - 8-32 Thread

These are 8-32 custom V bolts we had domestically produced for our customer.  Initially 12 pieces were run for prototype testing purposes prior to full production order.  The inside length to the bottom of the V is 1" and .625" between the legs.  0.6" of 8-32 thread is incorporated on both legs.  One thing to note with this type of bent part is that the threaded areas are clamped during the bending process - at minimum this results in a small visual dent in the threads and at worst, if over clamped the thread can be damaged to the point of creating issues running the mating parts.  We carefully inspect the parts to make sure this latter issue is avoided.  Unfortunately, there is no way to completely avoid grabbing on to the threaded areas for mass production that we have seem, without of-course limiting the amount of thread on each leg.

Light Brown Painted Button Socket Screws - 6/32 X 5/16 Tamper Proof Security Screws & Standard Socket Cap Screws

Our customer requested these light brown painted button socket screws in batches of approximately 2,500 pcs of both the security screw version and the standard button socket version.  Pin-in button socket drive was used for the security screw and both parts measured 6-32 X 5/16.  Alloy steel with thermal black oxide was used for the base part material, and the security screws had a wax coating that required stripping prior to the paint application.  Painting the screws without this stripping process would result in a good looking part until you actually tried to use them, at which point the paint easily chips and peels off the surface.  Unfortunately it's often difficult to discern whether the part has this wax coating or not, requiring a sample test run to be sure.

Custom Bent Eye Bolts & U-Bolts In A36 Steel Material - 3/4-10 Thread

These custom bent eye bolts were produced together with matching large round u-bolts in A36 material.  3/4-10 thread was incorporated on both parts and 6 eye bolts were produced together with 21 u-bolts, a relatively small production run.  Parts were produced within 4 days of order confirmation but could have been done faster with an expedited rush order and fee if necessary.  The diameter of the eye was set to 1-1/2" and the thread length was set to 2-1/2".  We were approx 1/4" shy of the thread length requested however as going beyond that would encroach onto the bending material.  The round u-bolts were made to 3-1/2" between the legs and 4" for the inside length.  1" of 3/4-10 thread was incorporated on each leg.

Custom Machined Aluminum Hardware - 6061 Aluminum With M6-1.0 Thread

Our customer was in urgent need when she ordered this custom machined aluminum hardware and was having a hard time finding anyone to run a small quantity while maintaining a fast turnaround.  We were able to come to the rescue with 24 total pieces and 16 days of lead time to get the parts completed.  This was done without an additional rush charge that could further cut this lead time to 1 week.  6061 aluminum material was used and M6-1.0 male and internal thread was incorporated on all the components.  The parts with the male thread included a slotted drive on the head, which is absent on the other two accompanying parts.

Custom Large Stainless Steel Spacers - 1/2" Round OD X 3 Inches In Length

Our architectural element construction customer ordered approximately 4,000 pcs of these custom large stainless steel spacers.  5/16-18 thread was incorporated internally, 1-1/4 inches of thread min on each side.  The gap between the two sides of thread was drilled all the way through for improved production time, allowing the entire part to be drilled through and then each side tapped on both sides.  The outside diameter was set at 1/2" and the overall length at 3".  Tolerances on all dimensions were +/- .015".  303 stainless steel material was used for production and material certs are available upon request.

Custom Slotted Fillister Screws - 303 Stainless Steel, DFARS Compliant

Custom slotted fillister screws we supplied to our aerospace customer at 100 pieces - ASTM A582 DFARS compliant 303 stainless steel material (Italy Melt) was used for the domestic manufacturing.  2-56 thread was incorporated at .25-.37" in length, with the overall length underneath the head at .625 +0/-.030".  The head height measures .070-.095" and the slot depth is set at .033-.043".  Head diameter was set between .145" and .161".  Full certs were provided with the parts per our customers usual requirements.
