Cold Rolled Clamp Screw

Cold Rolled Clamp Screw - Professional Formwork Fastening Solution 

Shandong Xingrui Building Materials Co., Ltd. manufactures high-precision Cold Rolled Clamp Screw products using advanced cold roll forming technology at our 79,800-square-meter production facility. Our clamp screws are cold-rolled and thread-formed from Q235 round steel, available in Φ32mm and Φ36mm diameters with common lengths of 500mm, 600mm, and 800mm.

With 4 sets of dedicated cold roll forming equipment and a team of 180 professional technicians, we ensure uniform hardness, excellent toughness, and high thread engagement precision. Each product undergoes strict quality inspection to meet ISO 9001 standards, delivering reliable performance for wall formwork tie reinforcement systems across more than 100 countries worldwide.

Technical Specifications of Cold Rolled Clamp Screw

​​​​​​​Superior Manufacturing Process

Our cold rolling and thread forming process creates a continuous grain flow structure that significantly enhances product durability. Unlike traditional cut threads that interrupt the metal's natural grain pattern, our manufacturing approach compresses and work-hardens the material surface.

This advanced technique produces threads with superior tensile strength and anti-wear properties. You'll benefit from thread profiles that maintain their integrity even after multiple installation cycles.

The process eliminates micro-fractures common in conventional machining. Your formwork systems gain reliable fastening components that resist thread stripping and maintain consistent clamping force throughout the construction project lifecycle.

Key Product Advantages

Precision Thread Quality

The cold-rolled threads feature exceptional dimensional accuracy and smooth surface finish. This precision ensures seamless engagement with various clamping devices, reducing installation time and preventing cross-threading issues during on-site assembly.

Enhanced Durability

Work hardening during manufacturing increases surface hardness by 20-30% compared to machined alternatives. Your formwork systems benefit from fasteners that withstand high-torque applications and resist fatigue failure in demanding construction environments.

Versatile Application

Available in multiple diameter and length combinations, our screws accommodate different wall thickness requirements. Whether you're working on residential projects or large-scale commercial developments, you'll find specifications that match your formwork opposite pulling back ridge needs.

Cost-Effective Reusability

The robust construction allows for multiple use cycles without performance degradation. You can significantly reduce project costs through repeated deployment across different construction phases and job sites.

Primary Application Scenarios

Wall Formwork Systems

These screws serve as critical tie rod components in wall formwork assemblies. They secure opposing formwork panels during concrete pouring, maintaining precise wall thickness and preventing formwork displacement under hydrostatic pressure.

Vertical Formwork Reinforcement

When combined with appropriate clamping devices, the screws provide robust back ridge fastening for vertical concrete structures. The anti-slip thread design ensures stable connection even in high-vibration concrete consolidation environments.

Adjustable Formwork Applications

The standardized specifications integrate seamlessly with various formwork systems including steel heavy-duty formwork, aluminum alloy formwork, and steel light-duty formwork configurations offered by Shandong Xingrui.

Quality Assurance System

At Shandong Xingrui, we implement comprehensive quality control measures throughout the production cycle. Our 920-person workforce includes specialized quality inspectors who conduct real-time monitoring of raw materials and finished products.

Every batch of Cold Rolled Clamp Screw products undergoes thread profile analysis and hardness testing. We maintain complete product quality traceability from Q235 raw steel procurement through final packaging.

Our ISO 9001 and ISO 14001 certified management systems ensure consistent product performance. You receive fastening components that meet international construction standards and deliver predictable results in field applications.

FAQ

Q：What makes cold-rolled screws better for formwork applications?

A：The cold rolling process creates compressed grain structure that enhances tensile strength. This manufacturing method produces threads that resist wear during repeated tightening and loosening cycles typical in formwork operations.

Q：Can these screws work with different clamping device brands?

A：Yes, our standardized Φ32mm and Φ36mm diameters follow industry-standard specifications. They're compatible with most commercial formwork clamping systems and tie rod assemblies used in concrete construction.

Q：How many times can I reuse these screws?

A：With proper handling and storage, our clamp screws maintain structural integrity through dozens of use cycles. The smooth thread finish prevents galling, and the uniform hardness resists deformation during normal construction operations.

Q：Do you provide custom length options?

A：Absolutely. While we stock 500mm, 600mm, and 800mm lengths, our 40,000-square-meter workshop can accommodate custom specifications based on your project drawings. Contact our technical team to discuss specific requirements.

Q：What delivery timeframes should I expect?

A：Our advanced production equipment and standardized processes enable efficient order fulfillment. Delivery schedules vary based on order volume and customization requirements, but our location in Rizhao provides excellent logistics access for international shipments.
