Custom Internally Threaded Square Pins - 12L14 Steel Material

 

Custom Internally Threaded Square Pins - 12L14 Steel Material
These custom internally threaded square pins were manufactured using 12L14 square bar stock material - sharp corners were absolutely critical and initial trial runs with alternative material options were unsuccessful until we finally found square bar material measuring very close to .69" across the corners.  The sharp corners allow the pins to lock at the remaining .14" long shoulder seen on the parts.  Both machined sides of the pins tightly fit into mating parts in the assembly.  Production was done at 25,000 pieces, with overall length at 2.25" and 1/4-20 internal thread on one side.
