We have supplied these custom grade 5 hex cap screws to our customer for well over 10 years.  The parts are manufactured domestically, with production runs typically covering 50,000 pieces at a time.  The shoulder is critical on these parts, set at .312" in diameter +/- .005" and at 1/4" in length.  Head dimensions slightly off the standard for this size and the finish is black oxide and light oil.  Together with a number of other parts we supply these custom hex cap screws through revolving annual blanket purchase orders that split up the annual usage to match our customer's seasonality.

Our long standing partnerships with over 1,000 production facilities all over the United States and abroad based on decades of custom hardware & fastener production history, in combination with the flexibility of blanket purchase arrangements, allows us to fully cater our customers’ custom fastener specification and procurement requirements.
