Double-ended hanger bolts combine a self-tapping wood thread with a machine thread and Torx head. Supplied as 30 M6x80mm bolts with a Torx bit for straightforward installation.
Secure wood-to-metal joints – With double-ended M6 threads
One end has a self-tapping wood thread that bites into timber, while the opposite end is a machine thread for accepting nuts; the machine end uses a Torx profile. Cleanly cut threads reduce movement between joined parts.
Strong mechanical connection reduces wobble and keeps furniture legs and brackets firmly fixed, ideal where rigid joints matter.
Corrosion and wear resistance – Thanks to carbon steel construction
Carbon steel is described as scratch-resistant and corrosion-resistant, giving higher hardness and long-term stability in use. The treated finish helps prevent rust in typical indoor and some outdoor settings.
Suitable for regular use on furniture and structural fittings where longevity is required, with less frequent replacement or maintenance.
Faster, more reliable assembly – With Torx bit and clean threads
A Torx profile on the machine-threaded end, paired with the included bit, reduces cam-out and allows higher torque without slippage. Well-defined threads ease alignment and tightening.
Quicker installations with reduced risk of stripping, useful for repetitive professional tasks or larger DIY projects.
