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

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

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

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

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.
