Description
Regular: A coiled, hardened, split circular washer with a slightly trapezoidal wire section.
High-Alloy: Dimensionally identical to a regular split lock washer
but made from 4037 alloy steel (sizes over 1" are equivalent to
heavy split lockwashers in size and material).
Stainless: A regular split lock washer made from austenitic stainless steel.
Applications
Regular: (A) Applies greater bolt tension per unit of applied torque;
(B) Provides a hardened bearing surface, creating more uniform
torque control; (C) Provides more uniform load distribution; (D)
Resists loosening caused by vibration and corrosion;(E) Is preferred
lockwasher for use with hardened bearing surfaces.
High-Alloy: Designed for use with Grade-5 & Grade-8 bolts and nuts.
Stainless: For use with stainless nuts and screws of a similar
stainless alloy in corrosive environments.
Advantages
Material
Carbon Steel: SAE J403 1055 - 1065 carbon steel.
High-Alloy Steel: 1/4 thru 1": SAE J404 4037 alloy steel; 1-1/8
thru 1-1/2": SAE J403 1055 - 1065 carbon steel
18-8 Stainless: SAE J405 302 - 305 stainless steel.
316 Stainless: SAE J405 316 stainless steel.
Hardness
Carbon & High-Alloy Steel: Rockwell C38 - 46
Stainless: Thru 5/8": Rockwell C35 - 43; Sizes over 5/8": Rockwell
C32 - 43
Twist Test
With the washer in a vice with the split ends free and straight above
the vice jaws, a 90° segment of the free end is gripped with a wrench and bent. Washers are to withstand being twisted through a 90° angle without signs of fracture. When the washer ultimately fractures beyond the prescribed 90° limit, the structure at the breaking point shall show a fine grain.
Plating
See Appendix-A for information about the plating of carbon steel and alloy steel lock washers.
