Fastener

Fastener is a standardized hardware accessory used to fasten and connect two or more components (such as steel pipes, profiles, rods, etc.), achieving rigid or flexible connection of components through mechanical clamping force or locking structure. It is widely used in fields such as construction, machinery manufacturing, transportation, warehousing and logistics. Its core function is to ensure the stability, safety, and operability of the connecting parts, and it is a "joint" component of various assembled structures. The following provides a detailed introduction from the aspects of classification, performance characteristics, application scenarios, and usage points:

1、 Main classification: Divided by function and structure

There are various types of fasteners, which can be divided into the following categories based on their connection methods and application scenarios:

1. Construction engineering fasteners

Right angle fastener (cross fastener):

The structure consists of two vertically intersecting semi-circular clamps, fastened with bolts, used to connect vertical and horizontal members (such as scaffolding uprights and crossbars), forming a 90 ° right angle node, which is the core connecting component of building scaffolding.

Rotating fasteners (universal fasteners):

The clamp can rotate around the central axis (0 ° -180 °), suitable for non right angle connections such as diagonal supports and scissor braces, enhancing the overall stability of the structure.

Docking clip (straight clip):

Used for extending the straight docking of two coaxial rods (such as when the length of the steel pipe is insufficient) to maintain the continuity of the force.

2. Industrial pipeline fasteners

Pipe clamp fasteners:

It is U-shaped or ring-shaped, and the pipeline is fixed to the support, wall and other foundations by bolts. It is commonly used in plumbing, HVAC systems and industrial pipeline installation. Some models come with rubber pads to reduce vibration or prevent slipping.

Flange fasteners:

Used in conjunction with a flange, connect two flanged pipes or equipment with bolts, providing both fastening and sealing functions (such as chemical pipeline connections).

3. General mechanical fasteners

Clamp type fastener:

Made of two half rings connected by bolts, it is used to quickly fix circular or irregular components (such as car exhaust pipes and cable protection pipes), and is easy to install and disassemble.

Hinged fastener:

Allow connecting components to rotate around the axis (such as door and window hinges, robotic arm joints), with both fastening and movable functions.
