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.  

Custom Partially Knurled Pins In Plain Steel Material - 6-32 Thread On One Side

These are custom partially knurled pins made using plain low carbon steel material.  One side is threaded at 6-32 with approximately .375 inches of thread while the other is diamond knurled at .20 inches max.  Overall length is set at .855 inches.  Production was done domestically at approximately 1,000 pieces.

Custom Shoulder Pins In Grade 2 Steel With Zinc Finish - 5/16 X 13/16 Shoulder

These are custom shoulder pins made using grade 2 steel material with zinc finish, manufactured overseas in Taiwan at approximately 100,000 pieces.  We supply them to our long time OEM customer on revolving 12 month blanket purchase orders, delivering parts as they need them.  The shoulder was maintained at 5/16 X 13/16".  Lead time for the initial lead time was 120-150 days, which is fairly typical for overseas parts with ocean freight.

Special 1/6 X .850 Hastalloy Sensor Pin

1/4 X 1/4 Alloy Dowel Pin to Print

Dowel pin specials are a common component of our special fastener offering to manufacturers and this particular part is a 1/4 X 1/4 dowel pin made using alloy steel to print.  Unlike many other fastener parts dowel pins are often more difficult to produce when tight tolerances are required, typically necessitating domestic US manufacturing of the parts.  This is particularly pertinent when working with miniature custom pins.
