ASME B18.8.1:2014 pdf free download Clevis Pins and Cotter Pins (Inch Series)
1INTRODUCTION1.1 Scope
1.1.1 This Standard covers the complete dimen-sional and general data for clevis pins sizes 3/16 in.through 2 in. and cotter (split) pins sizes /s2 in. through3/4in. of various materials.
1.1.2 The inclusion of dimensional data in thisStandard is not intended to imply that all productsdescribed are stock production items.Consumers shouldconsult with suppliers concerning the availability ofproducts.
1.1.3 There is no ISO standard comparable to thisStandard.
1.2 Dimensions
All dimensions in this Standard are given in inchesand apply before plating or coating. Tolerancing is inaccordance with ASME Y14.5.
1.3 Responsibility
The responsible party for the performance of the prod-ucts within the scope of this Standard is the organizationthat supplies the components to the purchaser and certi-fies or represents that the component was manufactured,tested, and inspected in accordance with this specifica-tion and meets all of its requirements.
1.4 Inspection and Quality Assurance
Unless otherwise specified by the purchaser, accept-ability shall be based on conformance with the require-ments specified in ASME B18.18.
1.5 Terminology
For definitions of terms relating to pins or featuresthereof used in this Standard, refer to ASME B18.12.
