Standard Specifications for Pole Line Fasteners

ANSI / ASME B1.1: Standard for Unified Inch Screw Threads (UN and UNR Thread Form).This specification specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads.

ANSI / ASME B18.2.1: Standard for Square and Hex Bolts and Screws. This Standard is intended to cover the complete general and dimensional data for the various types of inch series square and hex bolts and screws.

ANSI / ASME B18.5: Standard for Round Head Bolts (Carriage Bolts).This standard covers the complete general and dimensional data for the various types of inch series bolts

generally classified as round head bolts.

ANSI / ASME B18.15: Standard for Forged Eyebolts. This standard is limited to dimensions and capacities for forged threaded eyebolts intended primarily for lifting applications.

ANSI / ASME B18.2.2: Standard for Square and Hex Nuts. This standard is intended to cover the complete general and dimensional data for the various types of inch series square and hex nuts.



Standard Specifications for Hot Dip Galvanizing

ASTM A123: Standard Specification for Zinc (Hot Dip Galvanized) Coatings on Iron and Steel Products. This specification covers the requirements for zinc  coating (galvanizing) by the hot dip process on iron and steel products made from rolled, pressed and forged shapes,castings, plates, bars and strips.This specification covers both unfabricated products and fabricated products, for example, assembled steel products, structural steel fabrications, large tubes already bent or welded before galvanizing, and wire work fabricated from uncoated steelwire. This specification also covers steel forgings and iron castings incorporated into pieces fabricated before galvanizing or which are too large to be centrifuged (or otherwise handled to remove excess galvanizing bath metal).

ASTM A153: Standard Specification for Zinc Coating (Hot Dip) on Iron and Steel Hardware.This specification covers zinc coatings applied by the hot dip process on iron and steel hardware. This document is intended to be applicable to hardware items that are centrifuged or otherwise handled to remove excess galvanizing bath metal (free zinc).
