Internal / External Threaded Connector Nut Through Hole Hex Socket

Through Hole Hex Socket Internal External Thread Nut For Fastening Lighting And Furniture

The through-hole hexagon socket internal & external thread nut is a precision fastener integrating hexagon socket drive, axial penetration, and internal & external thread conversion functions. It realizes rigid connection of different components through specification adaptation of threads at both ends, and is widely used in mechanical transmission and equipment assembly scenarios requiring concealed fastening and reducing butt joint. Its structural design combines the dual advantages of high-strength fastening and flexible adaptation, making it a key component in industrial connections for solving specification mismatch problems.

• Hexagon Socket Drive Head: Adopts hexagon socket groove design compatible with hexagon socket wrenches (DIN 912 specifications). Can apply high tightening torque (recommended torque for M10 model: 25-30N・m), avoiding slipping, and suitable for concealed installation or space-constrained scenarios.
• Through-Hole Internal & External Thread Structure: Axially fully penetrating design with internal threads at one end (for connecting bolts/screws) and external threads at the other end (for adapting to female parts/sleeves). Thread precision reaches 6H/6g with complete thread profile and no broken teeth, ensuring connection concentricity ≤0.15mm for stable force transmission.
• Mechanically Optimized Transition: Transition area between head and thread section features arc chamfering (R≥0.5mm) to reduce stress concentration. Overall cold heading or forging forming ensures high material density without sand holes, with superior shear resistance compared to spliced nuts.

• Flexible Reducing Adaptation: Internal and external thread specifications can be customized (same diameter/reducing), solving mismatched thread specifications of bolts, sleeves, flanges and other components while reducing custom connector costs.
• Reliable High-Strength Fastening: 8.8/10.9 grade strength compatible with bolts of same grade. Maintains stable pre-tightening force under vibration and impact conditions, avoiding connection loosening, suitable for key nodes of mechanical transmission systems.
• Friendly to Concealed Installation: Hexagon socket head can be sunk into connector surface, reducing protruding height, improving appearance while avoiding collision interference. Especially suitable for exposed components of automated equipment and precision instruments.
• Strong Anti-Corrosion and Durability: Galvanized/passivated surface treatment effectively resists atmospheric corrosion; stainless steel material withstands humid and mild chemical environments, extending maintenance cycles.

• Mechanical Transmission Equipment: Reducing connection of shaft systems between motors and reducers, fixing of ball screw ends. Hexagon socket drive ensures high-torque fastening with internal & external threads adapting to different shaft diameter specifications.
• Automated Production Lines: Quick change parts of tooling fixtures, fixing of conveyor line guide rails. Reducing conversion function simplifies universal design of multi-specification tooling.
• Hydraulic and Pneumatic Systems: Adapter of pipeline joints, fixing of cylinder end caps. Through-hole structure doesn't block fluid/gas circulation with high-strength feature adapting to pressure environments.
• Precision Instruments and Meters: Fixing of test equipment panels, connection of sensor mounting bases. Grade A precision ensures assembly consistency with hexagon socket design meeting compactness requirements of instruments.

With its precise specification conversion capability, high-strength fastening performance and concealed installation advantages, the through-hole hexagon socket internal & external thread nut provides an efficient and reliable solution for industrial reducing connection scenarios, and is an indispensable precision fastener in mechanical manufacturing, automated equipment and other fields.
