scope:

This standard covers the requirements of inch-based: (1) zinc-coated ferrous carriage bolts, machine bolts, double-arming bolts, double-end bolts, washer-head bolts, eye bolts, eye nuts, and washer nuts; (2) zinccoated ferrous lag screws of the fetter drive, gimlet point, and twist drive type; (3) washers; and (4) staples, commonly used in overhead line construction. Metric bolts, nuts, and lag screws are not covered by this standard.

Purpose

This combined standard will provide a one-source standard for fasteners commonly used in overhead distribution and transmission lines. It will replace several active and archived standards that are currently in use to specify these fasteners.
