8640 ALLOY STEEL
HEX CAP SCREWS




THE ULTIMATE IN
HIGH STRENGTH ALLOY STEEL

Manufacturing Systems & Procedures Are REGISTERED TO ISO 9000 STANDARD

WHAT IS 8640 ALLOY ?

50%MORE CHROMIUM



AND 100%MORE NICKEL






TOUGH TESTED TRACEABLE


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.
