Product Overview & Material Specifications

Material Options

Premium Stainless Steel (SUS304 / SUS316) with exceptional corrosion and salt-spray resistance.

Drive Type

Anti-theft Torx with Pin (Security Drive) to prevent unauthorized disassembly.
 

Specification Range

Available in M4 to M10 diameters; barrel lengths can be customized to match various furniture panel thicknesses.

Technical Advantages & Engineering Design

To address the issues of inconsistent groove depth and internal thread defects in traditional processes, which lead to unstable assembly and a high defect rate (over 5%), we have implemented a process upgrade:

Stable Torx Drive Depth

We utilize precision-forged headers to ensure consistent Torx drive depth. This eliminates tool slippage and provides a high-torque, aesthetic finish for high-end furniture assembly.

Concentric Internal Threading

Our unique “Plug-Gauge Locked Alignment” during production ensures the internal thread remains perfectly parallel to the barrel. This prevents skewed installation and ensures seamless mating with the male screw.

Cold-Headed Precision & Automated Tapping

Every bolt is cold-headed for structural strength and then automatically tapped. 100% of products pass the Go/No-Go plug gauge test, ensuring a 99.9% smooth installation rate.

Industry Applications

Luxury Outdoor Furniture

The ultimate fastening solution for tables, chairs, and benches exposed to harsh weather, ensuring long-term rust-proof stability.

Public Park Infrastructure

Ideal for park benches and playground equipment where frequent movement and weather resistance are required.

Modular Architecture
