  • Black Oxide, followed by an appropriate post-treatment, provides limited added corrosion protection to the surface of the metal, prolonging service and increasing the shelf-life of stored parts. 

Standard Thread Length - If you have a specific thread length you need please call to verify.  The minimum thread length shall be equal to one-half the nominal screw length plus 1/2" or 6”, whichever is less. However some of our stock is truly custom and therefore please call if you need a specific thread length.
