MS20002/20002C |
|
Hardened Washers |
|
A high strength,
heat-treated washer which must be used ("C" version) with the
MS/NAS twelve point and internal wrenching bolts. The chamfer
matches the radius under the bolt head. Also good for use with
heavy torquing loads where ordinary steel washers would gall.
Note: Although the MS 20002 washers will fit over the shanks
of standard NAS (1103/1303/6403 etc.) hexbolts, the washer ID
is small enough that it will usually "crash" with the bolt
head-to-shank radius. DO NOT USE MS 20002 WASHERS UNDER THE
HEAD OF STANDARD NAS HEX BOLTS. All dimensions are in inches. |
