Custom Nickel Plated Socket Head Screws - 4340 Material

These custom nickel plated socket head screws were produced domestically using 4340 material instead of the originally requested 17-4PH version, with heat treatment to get the parts up to required 35-45 HRC hardness.  1/2-20 thread with 2A thread fit was incorporated with thread length of .77 inches.  Overall length underneath the head was set at 1.37" +.00/-.03".  The large .945" diameter head presented a challenge from the start for the cold heading operation - it took multiple sets of tooling and adjustments to finally get the head shape just right.

Custom Slotted Machine Screws For An Architectural Application

These custom slotted machine screws were made at a smaller 150 piece quantity for our architectural design customer.  They were made domestically using 18-8 stainless steel material with a relatively fast turnaround time of 2 weeks from order.  We replicated a sample part provided by our customer in the absence of a drawing.  1/4-20 thread pitch was incorporated with the thread length at 1-1/2 inches.  Our internal part number for this part is STS-1524-I.
