The pack includes 10 pieces, making it a practical choice for multi-piece assemblies, repairs, or kit projects. Typical uses include connecting timber to hangers or brackets where a powered, consistent grip is needed without cumbersome pre-drilling.
Features in focus: iron construction for strength; bronze tone for a classic appearance; total length 80 mm with M8 wood-thread on one end and machine thread on the other; versatile for joining timber to hardware with threaded fasteners. The product suits DIY woodworkers and professionals addressing furniture joints, hanger connections, or fixed-plank assemblies.
TOP-VIGOR 24Pcs M4x20mm Hanger Bolts
TOP-VIGOR’s 24-piece set demonstrates a practical approach to wood joints that require both a wood-thread and a machine-thread engagement. Each hanger bolt in this kit features a wood thread on one end for embedding into wooden structures and a machine thread on the opposite end for secure nut or washer connections. Constructed from high-strength carbon steel with a galvanized finish, these bolts offer durability and corrosion resistance in environments ranging from interior furniture projects to outdoor frames when protected. The M4x20mm size is ideal for lighter-duty joinery, cabinet work, and decorative fixtures where a clean, tight fit is critical.
Key points: dual-threaded design supports straightforward assembly; galvanized carbon steel provides long-term wear resistance; corrosion resistance makes them suitable for indoor and sheltered outdoor projects; convenient pack size for small to medium projects. These hangers excel in furniture joints that require nut-and-bolt connections without pre-drilling for the machine-thread side.

The galvanized finish adds protection for indoor environments where moisture exposure might occur, ensuring a longer service life for cabinetry and shelving projects.
Considerations include: appropriate for mid-size projects; compatibility with nuts and washers for machine-thread ends; finish consistency with other hardware; ease of installation due to self-tapping wood threads on the wood end.
Buying Guide: Key Considerations For Choosing Double-Ended Wood Screws
When selecting wood screws with machine threads on one end, several factors influence performance and longevity:
- Thread Types: A wood-thread end provides secure anchoring in timber, while the machine-thread end enables fastening with nuts or washers. Confirm your project requires both ends for a reliable joint.
- Material And Finish: Carbon steel with zinc or galvanized plating offers corrosion resistance and durability for indoor and sheltered outdoor use. For high-moisture environments, look for stainless steel variants.
- Length And Diameter: Match total length and machine-thread length to your project’s thickness and required seating depth. Longer machine-thread segments allow deeper connections and greater tensile strength.
- Finish Compatibility: Ensure the bolt finish complements other hardware (bronze-tone, zinc, etc.) for a cohesive look in furniture or cabinetry.
- Pre-Drilling And Self-Tapping: Some hangers are self-tapping on the wood end, reducing pre-drilling needs and minimizing wood cracking risk. Evaluate whether pre-drilling is acceptable in your project.
- Quantity And Storage: Kits with multiple sizes provide versatility for various joints. An organized plastic storage box helps manage different lengths and diameters across projects.
- Application Scope: Consider whether you need long, heavy-duty connectors for legs and frames or lighter hardware for drawers, knobs, and small joints.
In sum, these double-ended fasteners simplify wood-to-wood and wood-to-hardware assemblies, offering a practical blend of wood grip and machine-thread strength for a broad range of furniture, cabinetry, and DIY projects. Choose a kit with appropriate lengths, robust material, and corrosion resistance to ensure dependable performance over time.
