Description
A Hi-Collar washer is thicker and has a smaller outside diameter than a
regular split lock washer.
Applications
Designed for use with smaller head screws, particularly sockets. Performs comparably to a regular split lock washer as a greater thickness compensates for smaller outside diameter.
Advantages
Material
SAE 1055 - 1065 carbon steel
Hardness
Rockwell C38 - 46
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 Hi-Collar split lock washers.
