Doplňujúce informácie
| 1. Scope | ||||||||||||||||||||||||||||||||||||
| p>1.1 This specification covers the chemical, mechanical,
and dimensional requirements for metric hardened steel washers for
use with fasteners having nominal thread diameters M12 through
M100. These washers are intended for general-purpose mechanical and
structural use with bolts, nuts, studs, and other internally and
externally threaded fasteners. These washers are suitable for use
with fasteners covered in Specifications A 325M, A 490M, A 563M and
with fasteners of Specification F 568 property classes 8.8 and
higher.
1.2 The types of washers covered in this specification are: 1.2.1 Type 1—Washers made of carbon steel. 1.2.2 Type 3—Washers made of steel having atmospheric corrosion resistance and weathering characteristics comparable to that of steels covered in Specifications A 242/A 242M, A 588/A 588M, and A 709. The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition. See 5.1. When properly exposed to the atmosphere, these steels can be used bare (uncoated) for many applications. 1.3 The styles of washers covered in this specification are: 1.3.1 Circular Washers—Circular washers in nominal sizes 12 mm through 100 mm, are suitable for applications where sufficient space exists and angularity permits. 1.3.2 Beveled Washers—Beveled washers are square and rectangular, in nominal sizes 12 mm through 36 mm, with a beveled 1:6 surface for use with American Standard beams and channels. 1.3.3 Clipped Washers—Clipped washers are circular or beveled for use where space limitations necessitate that one side be clipped. Note 1—This specification is the metric counterpart of Specification F 436. 1.4 Terms used in this specification are defined in Terminology F 1789 unless otherwise defined herein. |
