Custom Long Socket Head Machine Screws - 8-32 & 8-36 Thread In 4140 Alloy Steel

 

Custom Long Socket Head Machine Screw Manufacturer- 8-32 Thread In 4140 Alloy Steel
These custom long socket head machine screws were manufactured domestically using 4140 alloy steel material with heat treatment to reach 37-44 Rc hardness.  Two sizes were produced together in this run: 8-32 X 5.43" length with thread length of 5/8" and 8-36 (an odd thread pitch requested for this one) X 6-3/8" with the same 5/8" thread length requirement.  The thread was cut rather than rolled for these parts and the hex drive was broached.
