NAS1957C38 A286 Superalloy Stainless Steel Hex Head Bolt 7/16-20  x 1 7/16 grip 2.03 in OAL Made in USA

Grip 1 7/16 in, thread length .595, overall length 2.03 inches

Fabricated with A286 Incoloy Superalloy processed to 180ksi minimum tensile strength

This alloy is also known as NAS Alloy 660 , UNS S66286

A286 is an age hardenable, nonmagnetic, austenitic stainless steel with 24-27% Nickel, 13.5 to 16% Chromium, and minor additions of Titanium, Vanadium, and Molybdenum

A286 Superalloy maintains high strength up to 1300 Deg F making it suitable for uses in jet engines, gas turbines, exhaust systems, and turbochargers

Dimpled hex head un-drilled

Dimpled hex head bolt for 9/16 inch wrench size

Ideal for aircraft, marine, aerospace and autosports use

Immune to corrosion in most environments

Better corrosion resistance, heat resistance, and strength than 18-8, 314, or 316 grade bolts

A grade 8 bolt is about 150ksi ultimate tensile strength, these are much stronger than Grade 8 strength with 180ksi UTS minimum

Do not confuse these made in USA National Aerospace Standard flight qualified bolts with cheap imports of unknown quality
