Core Info

Product: Long Hex Nut

Standard: DIN6334

Material: Q195,ZT195,08AL,SWRCH35K/45K,40CR,42CRMO,etc.

Property Class:6,8,10

DIN 6334 is a hexagon long nut defined in the German Industrial Standard (DIN), non-locking type of mechanical fastener with high connection depth, specially designed for scenarios requiring a long thread engagement length. Its core feature is that the nut height is much higher ordinary hexagon nuts (usually 3 times the nominal diameter), which enhances the tensile and shear strength by extending the thread contact surface, suitable for penetrating connections such as and studs.

Main Industry Application Scenarios

Construction engineering field; Mechanical and intelligent manufacturing field; Energy and new energy field; Transportation and aviation field; Marine and offshore engineering field; Electronic and precision manufacturing fields.

Core Features

a.High standardization and interchangeability:

Strictly defined dimensional parameters (thread specifications M5-M36, tolerance range (thread tolerance 6H) and mechanical performance requirements, highly compatible with ISO standards (such as ISO 4014/4017), most sizes are interchangeable, reducing procurement and assembly costs; products need to be marked with manufacturer codes, strength levels and DIN6334 identifications to ensure traceability.

b.Diverse materials and wide adaptability:

Available materials include carbon steel (4.8, 6.8, 8.8, 10 grades, etc., and carbon steel can improve rust resistance after being treated with zinc plating, blackening, etc.

c.Structural optimization and excellent performance:

The extended design (height3× major diameter of the thread) increases the thread engagement depth, and the tensile strength is significantly better than ordinary nuts; the full thread hexagonal shape design is not convenient for tool operation such as wrench, but also improves the efficiency of torque transmission, ensuring the convenience of assembly.

d.Quality controllable and high safety:

The standard requires products pass strict quality inspections, such as 100% magnetic particle flaw detection, to ensure no internal defects; clear strength level classification makes material selection more accurate under different working conditions reducing the risk of connection failure from the source.

e.Strong customization capability:

Special thread patterns, coatings or size specifications can be customized according to needs, adapting to nonstandard assembly scenarios; mainstream suppliers can provide value-added services such as free samples, quality inspection reports, etc., to meet the personalized needs of different industries.
