ASME B18.12:2020 pdf download.Glossary of Terms for Mechanical Fasteners.

2.1.8 MechanicaL Properties

mechanical properties: the properties of a fastener in reaction to applied loads. The mechanical properties of the fastener are

rarely those olthe raw material from which it was made. Properties such as tensile and yield strengths, hardness, and ductility

will vary widely depending on the choice of manufacturing methods and metallurgical treatments.

2.1.9 ModifIed Standard

modified scandard: a standard part that has one or more of its features or characteristics slightly changed. Such a part is

typically customized to a customer’s specs for a particular application, but the change is such that any interested manufacturer

can produce the modified part.

2.1.10 Nonstandard Fastener or Special Fastener

nonstandard fastener or special fastener a fastener that differs in size, length, configuration, material, or finish from

established and published standards.

2.1.11 Physical Properties

physical properties: inherent properties in the raw material that remain unchanged or undergo only slight alteration in the

fastener following manufacture, These properties may include density, thermal conductivity, and magnetic susceptibility.

2.1.12 Part Identifying Number (PIN)

Port Identifying Number (PIN): a 21-character code that Identifies an ASME BiB-manufactured product by specific characteristic

fields, such as fastener family identification, ASME BiB standard identification, fastener style or type, thread series, nominal

diameter, nominal length or dimensional/other characteristics, material and treatment, plating, coating. passivation, and special

features relevant to the fastener product.
