On The 458 Socom Phosphate Finished Bolts Are Better Than Nitride

So Carpenter 158 Steel Is The Absolute Best Steel On The Planet
For Bolt Heads Going On 50 Years Now.
158 Carpenter Steel Can Not Be Nitrided So That Is Why The Phosphate Finish
& Chrome Lining It Is So We Can Use The Strongest Steel Available Carpenter 158
