F-911 Bolt

The following information is directly from the manufacturer of these bolts.

"In the past, 8640 alloy was used in the manufacturing of only the most critical Aerospace and other special High Strength requirements. Now everyone can have this Superior Quality and Strength, with the "Off The Shelf" F-911 Hex Cap Screws and at prices comparable to other so called "Grade 9" bolts. What does 8640 Alloy offer? For starters, up to 50% more Chromium content and the substantial addition of Nickel, the ingredient that makes this Alloy tough. With higher Rockwell Hardness that the F-911 specification requires to achieve an over 190,000 P.S.I. Tensile Strength average, only 8640 Alloy can reach these lofty goals with superiority."

They are most definitely, in my opinion, an extremely high quality and high strength piece of hardware - fun bend!
