ABP Scaffolding
In modern structural engineering, the integrity of load-bearing configurations depends on the precision of sub-components. Among these, Jack Nuts (also known as petal nuts or blind expanding threaded inserts) and Scaffolding Base Handles represent the intersection of metallurgy and force distribution. These heavy-duty components ensure stability across structures ranging from high-rise office towers to complex nuclear power plants.
A Jack Nut is designed to provide secure threaded inserts in thin, soft, or brittle materials where tapping a thread is physically impossible. When tightened, the body of the jack nut collapses on the blind side to form four legs or "petals", distributing the clamping force over a wide load-bearing area. This reduces the risk of pull-out or structural failure under high vibration or cyclic loading.
Simultaneously, the scaffolding jack base nut and leveling handle assemblies act as the primary interface between the support scaffolding system and the earth. Manufactured using materials such as cast iron and high-tensile structural steel (like Q235 and QT450-10), these components support tons of dead weight while allowing precise vertical adjustment.
Utilizing premium QT450-10 Ductile Cast Iron and drop-forged Q235 steel, ensuring high load capacity and complete failure protection under extreme structural loads.
Fully compliant with BS1139, EN74 Class A & B, and certified by SGS. Our components undergo strict testing for chemical composition, hardness, and tensile limits.

Why Tier-1 global EPC firms choose Shandong ABP as their long-term supply chain partner
Located in Shandong, the heart of China’s steel fabrication industry, we benefit from direct access to top-grade Q235 carbon steel and high-ductility QT450-10 iron. This localized supply chain reduces input costs and lead times, giving our clients a strong competitive advantage.
Our entire catalog is engineered to comply with strict international standards, including **EN74-1 Class A/B** and **BS1139**. Each export batch is certified by **SGS** and **TÜV Rheinland**, and we provide complete material traceability reports (MTRs) for high-stakes projects.
With our in-house tool design and prototyping team, we specialize in high-capacity customizations. From adjusting the thread pitch of a 1/4"-20 steel jack insert nut to forging custom hollow screw base jacks with wing nut handles, we deliver exact configurations based on your CAD prints.
As building projects grow in height and complexity, global procurement departments are moving away from commodity-based sourcing. Today, decisions are driven by Total Cost of Ownership (TCO), longevity under harsh atmospheric conditions, and strict compliance with safety regulations.
Standard electro-galvanization often struggles in heavy offshore, coastal, or humid chemical environments, leading to red rust within months. Leading construction companies now demand Hot-Dip Galvanization (HDG) and zinc-alloy coatings. Our HDG processes provide a zinc barrier layer thicker than 65 microns, extending the service life of adjustable screw jack bases and handles to over 20 years in highly corrosive settings.
To improve safety and lower logistics costs, modern engineering firms are replacing heavy, unalloyed grey cast iron with high-tensile, lightweight **QT450-10 Ductile Cast Iron** and structural carbon steels like Q235. These advanced materials provide superior yield strength and load carrying capacity while keeping scaffold configurations lightweight and easy to handle.
In industries such as automotive assembly, high-speed rail, and panel installations, access is often limited to one side of the structure. Standard rivet configurations can cause structural cracking in wood or thin plastic sheet metals. High-performance **carbon steel blind jack rivet nuts** address this by expanding into a wide, four-petal shape that distributes clamping force evenly, protecting the substrate from fracturing.
Engineered to deliver exceptional stability in demanding civil, industrial, and maritime operations
Offshore drilling and nuclear power projects operate under strict safety tolerances. In these high-vibration, high-humidity environments, our drop-forged, hot-dip galvanized base jacks and wing nut support assemblies help maintain structural stability. Their robust design prevents shifting or loosening, ensuring reliable performance in harsh coastal and offshore settings.
Petrochemical refining involves high thermal variance and exposure to chemical emissions. The scaffolding structures surrounding cracking columns and pipelines must withstand continuous exposure. Our corrosion-resistant, zinc-plated, and galvanized scaffolding screw base jack nuts resist chemical wear, ensuring reliable support and safety during critical maintenance shutdowns.
Our M4, M5, M6, and M8 hollow folding blind rivet expansion jack nuts are widely used in automotive assembly lines to join composite materials, plastic panels, and thin sheet metals. Their unique four-way expansion distributes clamping force evenly, preventing strip-out, deformation, and stress cracking, even in high-vibration transport applications.
