SNZ AS/NZS 1252.1
High-strength steel fastener assemblies for structural engineering - Bolts, nuts and washers Part 1: Technical requirements
|Publication Date:||23 December 2016|
This Standard specifies the dimensional, material and marking requirements for steel bolt assemblies comprising steel bolts of property class 8.8, steel nuts of property class 8 with ISO metric coarse pitch series threads, in diameters from 12 mm to 36 mm, and associated hardened and tempered steel washers intended for use in steel structures. This Standard also specifies an additional bolt assembly type of property class 10.9 to EN 14399.3.
The bolt assemblies are intended to be fully tensioned but may also be used in a snug tight condition or where designed to be partially tensioned. This Standard also sets out tests to verify the suitability of high-strength bolt, nut and washer assemblies for tensioning (preloading) for bolted connections in steelwork construction.
This Standard is intended to apply to the manufacture of high-strength steel bolt assemblies.
NOTE: AS/NZS 1252.2 provides requirements for verification testing.
