Product Description
Metal Furniture Levelers are high-capacity, load-bearing adjustable components engineered to stabilize heavy industrial, hospitality, and residential furniture on uneven flooring. Designed with an articulated thread and a heavy-duty base plate, these Metal Furniture Levelers provide precision height adjustment, eliminate structural wobbling, and protect flooring from localized weight strain.
Load Capacities & Thread Integrity
High-Tensile Threaded Shafts: Forged from C45 carbon steel or SUS304 stainless steel with roll-formed threads that prevent thread stripping or shearing under extreme vertical loads.
Articulated Joint Stability: Features an integrated ball-and-socket base assembly, allowing the stem to pivot up to 15 degrees to compensate for sloped or irregular floor surfaces.
Vibration Dampening Bases: Available with chemically bonded Thermoplastic Elastomer (TPE) or vulcanized rubber base pads that absorb machinery vibrations and prevent floor scratching.
Heavy-Gauge Stamping: The bottom structural shell is constructed from thick-wall pressed steel, eliminating base flexing or dishing over long-term static placement.
Corrosion Resistance Coating: All metal surfaces are sealed with an 8-micrometer zinc plating, nickel-plating, or black passivation layer to withstand industrial washdowns and moisture.
Specifications
Standard thread lengths are 1.0 inch and 1.5 inch. Thread length can also be customized.
Machine Stress Verification & Tolerances
Operating from our automated Hua-tan facility, we run continuous automated cold-heading and high-speed thread-rolling machinery. Each manufacturing batch undergoes:
Vertical Compressive Crushing
Hydraulic press test systems verify the absolute static failure weight limits to guarantee the leveler exceeds standard commercial furniture ratings.
Thread Engagement Calibration
100% automated optical sorting machinery isolates and removes thread abnormalities, keeping pitch variation within +/- 0.05mm.
24-Hour Salt Spray Testing
Finishes are tested in a neutral salt spray environment (ISO 9227) to guarantee resistance against surface rust and chemical exposure.
Freight Optimization & Secure Packing
Weight-Optimized Container Stacking: Because heavy steel parts carry low volume but immense mass, we pack units in dense, reinforced five-layer BC-flute cartons calculated to maximize total container weight allowances.
Anti-Shift Pallet Arrays: Boxes are stacked symmetrically on ISPM-15 certified fumigated timber pallets, protected by thick corner boards and wrapped in industrial multi-layer plastic wrap.
Global Port Delivery: Execution of global contract shipping schedules via FOB (major Chinese ports), CIF (your local port), or DDP to your fulfillment facility.

FAQ
Q: How much vertical weight capacity can a standard set of four Metal Furniture Levelers handle?
A: The load limit depends on the chosen thread diameter and material grade. A standard M10 leveler manufactured from our hardened C45 carbon steel can easily support 300kg to 500kg per unit, giving a four-piece configuration a safe load capacity exceeding 1,200kg.
Q: Will the leveler base slide or mark delicate flooring like polished marble or hardwood?
A: For sensitive flooring, we recommend choosing our levelers equipped with soft TPE or rubber base pads. These materials offer non-marking characteristics, protect polished surfaces, and provide a high coefficient of friction to stop furniture sliding.
Q: Can these levelers be installed directly into hollow metal tubing legs?
A: Yes. To mount these levelers into hollow round or square metal tubes, they must be paired with our threaded tube end inserts. We can supply the complete matching set (leveler plus insert) calibrated to your tube's specific wall thickness.
Q: What is the advantage of using a pivoting swiveling leveler base over a rigid fixed base?
A: A swiveling leveler base uses a ball-joint mechanism that automatically conforms to angled or unlevel floors. This ensures the entire face of the base pad maintains contact with the floor, preventing point-loading and thread bending.
Q: What is your Minimum Order Quantity (MOQ) for non-standard custom thread lengths?
A: For standard catalog lengths, we offer flexible MOQ levels based on stock. For custom threaded lengths or specific step-stems, the MOQ aligns with a single machine setup run, which is typically 3,000 to 5,000 pieces depending on the product size.
Q: Can your factory provide customized drive interfaces like an internal hex socket on top of the thread?
A: Yes. We can integrate an internal hex socket into the top of the threaded stem during the cold-heading stage, allowing your assembly line operators to adjust height from inside the furniture frame using an Allen wrench.
Q: Do you provide material heat numbers or mill certificates before the balance payment is issued?
A: Yes. We prioritize full quality transparency for our commercial contract buyers. We supply comprehensive inspection packages for each shipment, including steel mill heat certificates, plating thickness validation data, and internal compressive test reports.
