Attaching furniture legs, TV mounts, or pipe shelving to wood shouldn't mean stripped screws or wobbly joints. These zinc plated hanger bolts give DIYers and tradespeople a clean, permanent stud in any wood surface — no head to get in the way, no slipping threads.
Available in M6 and M8 diameters with lengths from 40mm to 240mm, these headless hanger bolts feature a self-tapping wood thread on one end and a standard metric machine thread on the other. The Torx star drive tip prevents cam-out during installation, and select variants include a hex middle section for wrench-driven installation without touching the machine threads. Constructed from alloy steel with a protective zinc plating for corrosion resistance.
Ideal for sofa and chair leg replacement, wall-mounted TV bracket installation, pipe shelf brackets, boiler and heater mounting, and ceiling fixture anchoring into wood joists. Sold in packs of 5, 10, or 20 depending on size.
Drive the wood end into a sofa frame or chair base, then thread a replacement leg plate or metal bracket onto the machine end. Solid fix that won't loosen over time.
Create a permanent stud anchor in wood framing or wall studs. The machine thread end accepts the TV bracket nut directly — no toggle bolts needed when you hit solid wood.
Anchor pipe flange brackets, boiler supports, or heater mounting plates to wooden structural members. M8 and longer lengths handle the load requirements of utility installations.
Anywhere you need a threaded stud embedded in wood — workbench fixtures, jig anchors, ceiling-mounted tool holders — hanger bolts are the clean, professional solution.

Yes — always pre-drill a pilot hole slightly smaller than the wood thread diameter. For M6, use a 4.5mm (or 5/32") bit. For M8, use a 6mm (or 15/64") bit. Drill to a depth slightly greater than the wood thread length. Pre-drilling prevents splitting and makes installation significantly easier, especially in hardwood.
For variants with a hex middle section, simply place a wrench on the hex flats and drive the wood end into your pilot hole — the machine threads are never touched. For variants without a hex section, thread two nuts onto the machine end, jam them together, then use a wrench on the inner nut to drive the bolt. Remove the jam nuts once fully seated.
Yes — the zinc coating provides good corrosion resistance for covered outdoor applications such as deck fixtures, outdoor furniture legs, and sign brackets. For environments with constant salt spray or direct ground contact, stainless steel is recommended. For most covered porches, garages, and seasonal outdoor use, these perform reliably.
Absolutely — this is one of the most common applications. Drill a pilot hole into the furniture frame, drive the wood end in until the hex section (or thread transition) sits flush, then place the leg plate or bracket over the machine thread and secure with a nut and washer. The result is a solid, wobble-free repair.
For most TV mounts under 80 lbs, M8 × 50–70mm hanger bolts are typically sufficient. Drive the wood end into the center of the stud, leaving the machine thread protruding to accept the bracket nut. For heavier mounts (80–150 lbs), M8 × 80mm or longer is generally recommended. Always verify your bracket's hole diameter before ordering.
The "With Hexagonal" variants have a wrench flat (hex section) between the wood thread and machine thread zones. This lets you drive the bolt using a standard wrench without touching the machine threads. The "Without Hexagon" variants have a smooth transition between the two thread zones — installation requires the jam-nut method or locking pliers on the wood thread shank.
These are primarily designed for wood substrates. For concrete or brick, pre-drill with a hammer drill and masonry bit first — the wood thread end can grip in softer masonry when driven into a tight pilot hole, but for structural masonry applications, a dedicated concrete anchor is typically the more reliable choice.
No — nuts and washers are not included. These hanger bolts accept standard metric nuts (M6 or M8 depending on the variant). Nuts and washers are available separately.
