Technical Reference
Fastener Standards
Fastener selection is governed by corrosion class, substrate material and structural load requirements. The following standards apply to fasteners used in Australian steel construction and metal roofing applications.
AS 3566.1:2002
Self-Drilling Screws — General Requirements
Specifies dimensional requirements, mechanical properties and test methods for self-drilling screws used in building and construction. Covers thread form, drill point geometry, hardness and torsional strength.
AS 3566.2:2002
Self-Drilling Screws — Corrosion Resistance
Defines four corrosion resistance classes: Class 1 (internal, non-corrosive), Class 2 (internal, moderate), Class 3 (external, non-marine), Class 4 (external, marine/aggressive). Class 3 minimum for all external roofing and cladding applications.
AS/NZS 1110.1:2011
ISO Metric Hexagon Bolts & Screws
Specifies dimensions and tolerances for ISO metric hexagon bolts and screws. Grades 4.6, 8.8 and 10.9. Used for structural connections in steel framing, purlins and girts.
AS/NZS 1237.1:2004
Plain Washers for Metric Bolts
Specifies dimensions and tolerances for plain washers used with metric bolts and screws. Hardened washers required under bolt heads and nuts in structural connections.
AS/NZS 4291.1:2000
Mechanical Properties of Fasteners — Bolts
Specifies mechanical properties (tensile strength, yield strength, hardness) for metric bolts, screws and studs. Grade 4.6 (general purpose), Grade 8.8 (high-strength structural), Grade 10.9 (high-strength friction grip).
AS/NZS 3678:2016
Structural Steel — Bolted Connections
Governs the use of structural bolts in steel connections. Specifies bolt grades, hole tolerances, minimum edge distances and end distances for bolted connections in structural steelwork.
