When you need a fastener that threads into wood on one end and accepts a nut on the other — without a bolt head getting in the way — a hanger bolt is the right tool. These 304 stainless steel hanger bolts feature a wood-screw thread on one end and a machine thread (M8×1.25mm, M10×1.5mm, or M12×1.75mm) on the other, making them ideal for furniture legs, equipment mounting, and structural timber connections where a clean, headless installation is required.
Manufactured from 304 stainless steel (18-8 grade), these hanger bolts offer strong corrosion resistance for both indoor and outdoor use. Available in lengths from 30 mm (~1-3/16") to 250 mm (~9-13/16"), sold in packs of 10 pieces. The machine-thread end accepts standard metric nuts and washers for secure, adjustable clamping.
Common applications include table and chair leg attachment, wall-mounted bracket installation, outdoor furniture assembly, small machinery repair, and any project requiring a threaded stud embedded in wood or soft material.
Attach table legs, chair legs, and sofa feet cleanly without exposed bolt heads — the wood-screw end embeds flush, leaving only the machine thread for the nut.
Use M10 or M12 hanger bolts for deck railings, pergola connections, and outdoor furniture where 304 stainless steel's corrosion resistance is essential.
Mount motors, brackets, and equipment bases to wooden platforms or composite panels using the appropriate thread size for the load requirements.
Install wall-mounted shelving brackets, hanging fixtures, and decorative hardware with a professional, clean finish — no visible bolt heads on the finished surface.

A hanger bolt has no head. One end has a wood-screw thread that drives directly into timber, and the other end has a standard machine thread that accepts a nut. This allows you to create a threaded stud embedded in wood — useful for attaching furniture legs, mounting brackets, or connecting components where a bolt head would be visible or obstructive.
Thread two nuts onto the machine-thread end and lock them against each other (jam-nut method). Use a wrench on the outer nut to drive the wood-screw end into a pre-drilled pilot hole. Once installed, remove both nuts. Alternatively, use locking pliers on the smooth center section if present, or a hanger bolt driver bit if available.
For M8 hanger bolts, drill a pilot hole of approximately 5.5–6 mm in softwood, or 6–6.5 mm in hardwood. For M10, use 7–7.5 mm in softwood or 7.5–8 mm in hardwood. For M12, use 8.5–9 mm in softwood or 9–9.5 mm in hardwood. Always test on scrap material first, as wood density varies.
Yes. 304 stainless steel offers good corrosion resistance for most outdoor and humid environments, including garden furniture, decking, and covered outdoor structures. For highly corrosive environments (saltwater coastal areas or chemical exposure), consider 316 stainless steel instead, which offers superior chloride resistance.
M8×1.25mm is suitable for lighter furniture like chairs, small tables, and decorative brackets. M10×1.5mm handles medium loads such as dining tables, shelving units, and equipment bases. M12×1.75mm is for heavy-duty applications including large outdoor furniture, structural timber connections, and machinery mounting. When in doubt, size up for safety.
The machine-thread end accepts standard metric hex nuts, flange nuts, and washers in the corresponding size (M8, M10, or M12). Standard metric thread pitch is used (M8×1.25mm, M10×1.5mm, M12×1.75mm), so any standard metric hardware will fit. Wing nuts can also be used for tool-free adjustment in non-structural applications.
As a general rule, the wood-screw end should penetrate at least 2–3 times the bolt diameter into the wood for a secure hold. For example, an M8 hanger bolt should embed at least 16–24 mm into the timber. Add the required machine-thread length for your nut and clamping material to determine the total bolt length needed. For furniture legs, 40–60 mm is typically sufficient; for structural connections, 80 mm or longer may be required.
