Products Description
A double-ended bolt is a bolt with a clearly defined specification. "M6" indicates that its thread outer diameter is 6 millimeters. In practical applications, it can be used to connect two components with threaded holes, or to connect a component with a threaded hole to another component that requires a nut for fastening. It plays a vital role in scenarios such as the assembly of electronic equipment enclosures and the connection of small metal structures.

Applications
Automotive & Motorcycle Manufacturing
Applied for mounting engine cylinder heads, exhaust manifolds, motor brackets and chassis auxiliary parts. It withstands thermal expansion cycles and running vibration, easier to replace than full bolts for frequent maintenance components.
General Machinery & Automated Production Lines
Used to fasten equipment frames, CNC fixture bases, robot sliding rail supports and conveyor assembly joints. Works well in narrow confined spaces where standard hex bolts cannot be tightened from both sides.
Chemical, Power & Energy Equipment
Serves flange connections on small pipelines, reaction vessel auxiliary mounts and coal/ash conveying wear liner fixing. Stainless steel M6 studs deliver stable anti-corrosion performance for damp, acidic or high-temperature operating environments.
Mining & Metallurgical Machinery
Secures light-duty ore chute brackets, continuous casting auxiliary guide fittings and vibrating screen minor assembly parts. Offers reliable clamping against moderate abrasive dust and fluctuating working heat.
Construction & Building Electrical Works
Fastens electrical junction boxes, cable tray brackets and concrete-mounted support arms. Zinc-plated M6 studs enable quick threaded anchoring onto concrete and steel structural substrates.
Marine, Hydraulic & Light Fabrication
Fits small hydraulic linkage assemblies, boat deck fixture mounts and aluminum extrusion frame connections. Anti-rust stainless variants resist salt spray and moisture erosion for long-term outdoor or underwater light-load use.
