Stainless Steel Plug M10, CNC Threaded Sealing Plug for Industry
Product Overview
This hex head plug screw is integrally CNC machined from RoHS compliant stainless steel. It features precise thread and hexagon dimensions with reliable sealing performance, widely used as sealing and blocking parts for industrial pipelines, hydraulic & pneumatic equipment and instrument enclosures.
Application Scenarios & Requirements
Hydraulic & Pneumatic Systems
Mainly used for blocking ports of hydraulic stations, cylinders and oil pipelines. It requires excellent pressure resistance and tight thread fit to prevent leakage under high pressure. The structure maintains high strength, and threads will not slip or deform after repeated assembly and disassembly.
Industrial Fluid Pipelines
Applied to port blocking of water supply, drainage and chemical fluid pipelines. The product needs outstanding corrosion resistance to withstand erosion from conveyed media. Stable surface performance prevents rusting and ensures long-term sealing effect.
Mechanical Equipment Housings
Used to block reserved holes on machine tools and automated equipment housings. It requires smooth appearance and consistent dimensions. The standard hex head allows easy assembly with common tools, and blocks dust and debris effectively.
Instruments & Meters
Serves for interface blocking of precision testing devices. The RoHS compliant material ensures no harmful substance precipitation. Strict dimensional tolerance guarantees no negative impact on overall equipment precision.
Industry Points & Solutions
-
Leakage under high pressure
Plugs with low thread precision tend to lose sealing performance under high pressure. Our products adopt CNC precision machining with tightly controlled thread tolerance and smooth end face, realizing stable sealing under pressure.
-
Rust and damage in harsh environments
Ordinary fittings are prone to rust and jam in humid or corrosive conditions. Made of RoHS compliant stainless steel, the product delivers good rust and corrosion resistance for longer service life.
-
Difficult assembly and slipping during fastening
Poorly processed shapes cause tool slipping. The standard precision-machined hex head ensures firm clamping for easy installation and reliable locking.
-
Inconsistent precision among batch products
Traditional processing leads to dimensional deviation and poor compatibility. Adopting full-process CNC production with unified parameters, all products in the same batch keep consistent precision and appearance.
