M5/M6/M10 304 stainless steel hexagonal copper head machine rice screw plunger buffer screw inlaid copper setting top wire for Machinery & Equipment

Our 304 Stainless Steel Hexagonal Copper Head Machine Screws (M5/M6/M10), also known as plunger buffer screws, inlaid copper set screws, and socket set screws, are professional high-precision fasteners engineered for industrial machinery, equipment maintenance, and hardware fastening applications. Crafted from premium 304 stainless steel, these screws deliver exceptional corrosion resistance, rust protection, and mechanical strength, ensuring long-lasting performance in harsh industrial environments.

 

Featuring a hexagonal socket design and inlaid copper head (plunger buffer structure), these set screws offer precise, secure fastening with superior shock absorption and anti-loosening performance. The copper insert provides a soft, non-abrasive contact surface, preventing damage to the fastened components while enhancing friction and stability—ideal for machinery parts that require tight, vibration-resistant connections. The hexagonal socket drive allows for easy installation and tightening with standard hex tools, ensuring a secure fit even in tight or hard-to-reach spaces.

 

Precision-machined to meet strict industrial standards, the M5, M6, and M10 sizes offer universal compatibility with a wide range of machinery components, equipment panels, and hardware fittings. The 304 stainless steel construction resists rust, corrosion, and wear, making these screws suitable for long-term use in humid, high-temperature, or chemical-exposed industrial settings. The plunger buffer design further enhances their functionality, making them perfect for applications that require shock absorption and stable fastening.

 

Versatile and reliable, these screws are widely used in industrial machinery assembly, equipment maintenance, hardware installation, and precision mechanical projects. Whether you’re a professional machinery technician, industrial buyer, or hardware manufacturer, these 304 stainless steel hexagonal copper head set screws deliver the precision, durability, and performance needed to keep your equipment and projects secure. Engineered for consistency and reliability, they are a trusted fastening solution for industrial and mechanical applications.
