Timber Bolt
This timber bolt is a heavy-duty anchoring fastener developed for wooden utility poles and power transmission foundation installation, classified as professional overhead line power fitting. It features an integrated forged structure with a large round disc pressure head, smooth solid shank and partial metric threaded tail.
Manufactured from high tensile medium carbon steel via integral hot forging, the timber bolt delivers outstanding pull-out resistance and load-bearing capacity to sustain long-term static tension of stay wires on wood poles. Full hot dip galvanization covers the entire surface to form a compact thick zinc coating, offering superior resistance against rain, snow, humidity and coastal salt mist, perfectly suited for long-term outdoor power operation environments.
The wide circular plate head expands the compression contact area inside concrete or timber substrates, effectively preventing bolt displacement and pull-out under heavy cable tension, which solves the loose anchoring problem of traditional straight anchor rods on wooden poles. The smooth cylindrical shank reduces friction during embedding, and the precision partial thread at the tail cooperates with standard square nuts to realize flexible tension adjustment of guy wires during installation and daily line maintenance.
Timber bolts are widely applied to wooden utility pole foundation embedding, overhead distribution line stay anchoring, transmission tower guy wire fixing and rural power grid infrastructure projects. It is the core load-transfer fastener to fix wood poles and transfer overhead wire tension into underground concrete foundations.
We support fully customized production based on customer drawings and samples, including adjustable overall bolt length, thread diameter, disc head diameter and galvanized layer thickness. Custom brand logos can be stamped on the disc surface. All timber bolts undergo rigorous pre-delivery quality inspections including ultimate pull load test, zinc coating thickness detection and thread matching verification, ensuring stable anchoring performance and extended service life for all power construction projects.
