Digest 301 Corrosion of metals by wood

Good Building Guide 21 Joist hangers
The use of joist hangers provides a quick, economic and reliable method for forming timber-to-timber joints and for supporting timbers on masonry or steel beams. This guide shows how to use hangers to support timber joists in new construction work, and stresses the importance of correct specification and installation to ensure good performance.

Guidance Document GD 7 Multiple fastener timber joints: guidance on BS 5268-2 and Eurocode 5. (January 2003 revision)
Document History - Revised January 2003
Document explains the factors which affect the strength of multiple fastener joints and describes relevant research in this field. Provides new design recommendations for both BS 5268-2 and Eurocode 5.

Wood Information Sheet 2.3/51 Timber engineering hardware and connectors
The term 'timber engineering hardware' encompasses a diverse range of metal components made of steel plate, sheet or strip which are used to connect timber members together, usually in conjunction with dowel-type metal fasteners. Timber engineering components have widely replaced traditional carpentry joints due to their ease of use, ready availability and the avoidance of complex machining of timber members. Typical examples of common types include joist hangers, framing anchors, truss clips and wall ties. Mass-produced timber engineering hardware is usually made from pre-galvanised mild steel, from 1mm-3mm thick. However, heavier components are also made for large structures in thicknesses up to 12mm, sometimes in proprietary forms. These thicker components are usually galvanised after manufacture; this has the advantage that the edges, which are otherwise exposed by cutting or drilling, are fully protected. Some manufacturers also supply stainless steel components to order.

Wood Information Sheet 2.3/52 Fasteners for structural timber: nails, screws, bolts and dowels
Document History - Revision replaces 1995 version
Summarises the characteristics of different fasteners for structural timber. Also broadly considers design in relation to spacing rules, lateral loading, axial loading, slip, fire resistance and comparative performance.
