Thread knob handle nuts refer to industrial handle. Compared to other products, they have a number of differences. 

Special features of the clamping knobs

Handle shape: 

  • star-shaped, with projections which ensure a good grip with your hand. Number of blades - three, four, five, six; 
  • spherical,
  • drop, 
  • wheel. 

Design. With plugs, one-piece, on a chain, with key.

Attachment method. Mounted to the surface by means of internal or external threads, usually from M6 to M20. This allows a good hold and fixation of the door.

Material. A variety of materials are used for manufacturing: bakelite, duplast, polyacetal, steel, stainless steel, cast iron, brass, zinc alloys. In different cases, the materials are subject to the following requirements:

  • fire-resistant;
  • unconductive;
  • resistance to impact, wear and tear;
  • resistance to chemically active compounds (oils, alkalis, acids, etc.). 

Application of thread knob handle nuts

  • At especially high temperatures. 
  • Suitable for aggressive environments. 
  • On live surfaces, where there is a risk of electrocution. 
  • For parts which may be damaged, where a non-marking clamping force is required.  
  • For installations where a tight seal is required.
