Custom Coupling Nuts With Nylon Patch - 5/16-18 X 1.5"

We had 10,000 pieces of these custom coupling nuts with nylon patch produced for our customer using 18-8 stainless steel material with partial internal thread.  The drilled hole depth was at 19MM max and 16MM of that depth was to be threaded.  Across the flats measures .500" and overall length at 1.5".  The undrilled side required a 45 degree chamfer resulting in a .40" diameter round base.  Nylon patch was applied at 180 degrees after the first 2 threads.

Custom Machined Hex Nuts - Oversize With 3/4-10 and 5/8-11 Internal Thread

These oversize custom machined hex nuts were made domestically using plain low carbon steel material, to be used in a custom u-bolt/plate combination after all 3 items went through a zinc plating process.  Width across the flats was set at 2" for both the 3/4-10 and the 5/8-11 internal thread versions, and the height was at 3/4".  Parts were completed within 2 weeks of order, with an additional 1-2 weeks for zinc plating with the other two items.  Our internal part number for this machined hex nut is NF-075032-B.

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.
