Products Description
principle of operation
Slotted Round Nuts DIN 1804
Stop washer fit: clamp inner tongue of stop washer into nut groove, and bend outer tongue to shaft groove or part groove to form a mechanical interlock.
Lock pin fixation: insert slot and shaft hole through pin to limit nut rotation.
Elastic self-locking (specially designed):
Radial elastic deformation of groove occurs after compression, which increases friction of thread contact surface and realizes loosening prevention.

Knowledge expansion
Historical evolution: Slotted Round Nuts DIN 1804 was first used for the axle fixation of steam locomotive in the 19th century, and then standardized with the development of precision machinery.
Innovative design: modern derived laser slotted nut with higher accuracy; or integrated sensor monitoring pretension.
Simulation optimization: simulate the stress distribution of the groove through finite element analysis (FEA) to optimize the ratio of groove depth and groove number.
Through reasonable selection and standard installation, Slotted Round Nuts DIN 1804 can effectively guarantee the long-term stable operation of the rotating parts, and is an indispensable key fastener in the mechanical design.
