Custom Tapered Grade 5 Socket Head Screws - 10-32 Thread

 

We had these custom tapered grade 5 socket head screws produced for our sports product manufacturing customer with black oxide finish.  10-32 2A thread was rolled at a length of .36 +/- .03" and the head height was set to .14".  Head diameter was designed for .286" +/- .01" and a 1/8" hex socket drive was cold formed.  Our original production batch was sadly lost in transit with Fedex but we were able to push through to get replacement parts manufactured and delivered within 4 weeks to avoid a line shutdown with our customer.

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.
