Fastener

Product Overview

Scaffolding couplers are specialized fasteners designed to connect Φ48‑series steel tubes in construction scaffolding. Used in conjunction with coupler‑type steel tube scaffolds, they securely join vertical posts, horizontal rails, diagonal braces, and scissor bracing, ensuring the overall stability of the scaffold structure and serving as a critical safety component on construction sites.

Product Structure Features

Curved, conforming clamp design that perfectly encircles the steel pipe, ensuring even stress distribution and minimizing slippage and displacement.

Thickened fastener housing ensures load-bearing capacity without cracking, providing a high safety factor for high-altitude operations.

T‑shaped bolt with extended threaded shank, offering ample adjustment range; it can securely clamp both thick and thin steel pipes, ensuring a tight and reliable fastening.

The edges and corners are smoothly rounded, with no sharp burrs, reducing the risk of injury to workers during installation.

Easy to assemble and disassemble—simply use a wrench for quick tightening and loosening, boosting the efficiency of scaffolding erection and dismantling.

Product Advantages

High load-bearing capacity, safe and stable

Manganese steel offers excellent impact resistance and slip resistance; once tightened, the steel tubes remain securely locked, eliminating the risk of frame deformation or tilting and meeting the standardized inspection requirements for construction sites.

Rust-resistant and durable, suitable for reusable circulation.

Galvanized fasteners are waterproof and rust‑proof; they resist corrosion even under prolonged exposure to sun and rain, can be reused multiple times on construction sites, and maintain low wear over long-term use.

Highly versatile and widely compatible.

The standardized system is compatible with all Φ48 steel pipes on the market and can be used in three configurations—right-angle, swivel, and butt joint—to meet all scaffolding erection requirements.

Easy to disassemble and assemble, with efficient construction.

Standardized bolt components can be fastened and removed using only a single adjustable wrench, significantly reducing scaffolding installation time.

Costs are controllable, and the price-performance ratio is high.

Low unit cost and reusable, it offers lower procurement and rental expenses than disc‑type fasteners, especially for small‑scale projects.
