SS Jam Nut Properties

Description A six sided internally threaded fastener which is only 2/3 he thickness of a full form nut.
Applications
& Advantages		 Jam nuts are tightened against the work surface and a heavy hex nut is tightened against the jam nut to keep it from loosening.
Material Steel: Nuts shall be made from a low carbon steel which conforms to the following chemical composition requirements: Phosphorus: .12% max Carbon: .47% max Sulfur: .23% max
Stainless: Nuts shall be made from one of the following austenitic stainless alloys" 303, 303SE, 304 or XM7, all of which have a chromium content of 18% and a nickel content of 8%.
Heat Treatment The austenitic alloys develop their strength through work hardening during the manufacturing process, as seen from their hardness properties below. The only heat treatment normally available on austenitic stainless steel alloys is annealing, which is done at approximately 1900°F to a dead soft condition and is not normally thermally reversible.
Core Hardness Steel: Rockwell B68 - C32
Stainless: Rockwell B95 - C32
Proof Load Steel: Course thread: 54,000 psi Fine Thread: 48,000 psi
Stainless: 1/4 thru 1/2 inch - 60,000 psi
