Double Threads Hanger Bolt

This specialized dual-design enables direct self-tapping locking on wooden substrates and precise threaded engagement with metal nuts, brackets and hardware fittings. Different from conventional single-thread furniture screws and exposed fasteners, this headless hanger stud delivers hidden installation, flush flat finish and ultra-stable composite connection, widely adopted in high-end custom cabinets, wooden furniture sets and indoor decorative structural projects.

Integrated Forging Molding & High-Precision Thread Machining Craft

All our double thread hanger bolts adopt one-piece integral forging and full-automatic thread rolling process, zero welding splicing, ensuring complete structural integrity and uniform stress distribution. The wood thread section features sharp cutting teeth and optimized thread pitch, lowering tapping resistance and effectively preventing wood board cracking during installation. The machine thread end is manufactured by secondary precision rolling, achieving standard tooth profile, smooth meshing and tight tolerance for perfect compatibility with international standard hardware. The middle smooth rod body enhances positioning accuracy and assembly flatness. After strict integral heat treatment, the bolts obtain balanced hardness and toughness, effectively preventing thread slipping, tooth breakage and structural fatigue. Multiple anti-corrosion surface treatments including electro galvanizing, color zinc and black passivation greatly improve rust resistance and service stability for long-term indoor and humid environment application.

Product Parameter

Product Functional Edge & Furniture Engineering Application Scenarios

1. Dual-thread integrated multi-functional design. This hanger bolt combines wood tapping and metal threaded connection into one component, realizing fast switching and matching of wood-wood and wood-metal connection. It simplifies installation procedures, reduces accessory matching costs and significantly improves production efficiency for furniture batch assembly lines.

2. Premium invisible assembly effect. The headless structure eliminates protruding fasteners after installation, maintaining a smooth and flawless surface of furniture products. It effectively enhances product appearance grade, perfectly fitting the minimalist and high-end customized furniture design trend.

3. Excellent anti-loosening and structural stability. The deep-groove wood thread forms a large-area locking bite with wooden materials, while the standard machine thread ensures tight meshing with metal accessories. The integral rigid structure resists daily vibration, pressure and ambient temperature changes, maintaining long-term stable connection without loosening or shaking.

4. Optimized anti-cracking and wear-resistant performance. The streamlined sharp thread tip reduces installation resistance to avoid board splitting during self-tapping. The precision rolling thread surface features high wear resistance, preventing tooth slipping and abrasion after repeated disassembly and long-term use.

5. Wide compatibility and reliable cost performance. Compatible with density boards, plywood, solid wood and various standard metal fasteners, it meets diverse furniture assembly demands. With stable batch quality and flexible customization capability, it is the preferred matching fastener for furniture manufacturers and hardware distributors.

FAQ

Q1: What is the core difference between hanger bolts and ordinary furniture screws? 

A1: Hanger bolts adopt headless dual-thread structure for invisible cross-material connection, focusing on seamless and high-grade assembly effect; ordinary headed screws are exposed single-function fasteners, suitable for conventional surface fixing. The two have completely different structural positioning and application scenarios.

Q2: Can this stud bolt connect wood and metal parts firmly? 

A2: Absolutely. The product is professionally designed for composite connection scenarios. The wood thread end locks wooden components tightly, and the machine thread end stably matches metal brackets and nuts to achieve integrated and firm assembly.

Q3: Is pre-drilling required during actual installation? 

A3: Pre-drilling is recommended for hard solid wood and ultra-thick boards to avoid cracking. For density boards, plywood and soft wood materials, direct self-tapping installation is available for efficient construction.

Q4: Does headless design sacrifice fastening strength? 

A4: No. The one-piece forged structure ensures uniform force bearing. The double-section threaded engagement provides excellent tensile resistance and anti-loosening performance, fully meeting the load-bearing and safety standards of furniture structural connection.

Q5: Do you support personalized non-standard customization? 

A5: Yes. We provide full-range customization services including special bolt length, thread proportion adjustment, exclusive surface treatment and laser logo marking to meet personalized engineering and product supporting demands.
