SGL series precision balance nuts

SGL-F


SGL-F Tooth-Bottom Lock
This type of nut features a 30° thread angle and a three-point locking mechanism. Its superior locking design ensures that the thread on the fixing copper part perfectly mates with the male thread, guaranteeing a flawless anti-loosening effect. Furthermore, the 30° angle design reduces the torque generated when tightening the screw. The nut's internal thread, end face, back surface, and outer diameter are all precision-ground to meet the precision requirements of high-speed rotation.

  • Material: SCM440 (42CrMo4) Quenched and tempered
  • Planar runout: 0.002mm
  • Parallelism: 0.002mm
  • Thread precision: ISO 4H precision grinding
  • Hardness: HRC 28° ~ 32°
  • Concentricity: 0.005mm

SGL-A Axial Locking
This type of nut uses an axial three-point locking mechanism. Its thickness is the same as the SGL-F series, and the axial three-point locking is its key feature, making it suitable for special environmental constraints in assembly work. The nut itself has internal threads, end faces, back faces, and outer diameters all precision-ground to meet the precision requirements of high-speed rotation.

SGL-K


SGL-K Tightening Lock
This type of nut utilizes the inherent elasticity of steel for axial locking and forced locking. This product is specifically designed for harsh working environments where nuts are prone to loosening, offering more than three times the locking capability of traditional nuts. The nut's internal threads, end face, back surface, and outer diameter are all precision-ground to meet the precision requirements of high-speed rotation.

  • Material: SCM440 (42CrMo4) Quenched and tempered
  • Planar runout: 0.002mm
  • Parallelism: 0.002mm
  • Thread precision: ISO 4H precision grinding
  • Hardness: HRC 28° ~ 32°
  • Concentricity: 0.005mm
