Specification
Information
Knurled nut: Steel, black oxide finish, tapped through

Quick release knurled nuts GN 6303.1 are used in such applications where the nut has to be completely removed after the releasing operation and refitted very rapidly for re-clamping.
The nut is tilted over the threaded spindle. When in position, the nut is brought into a straight position for meshing of the two threads on nut and spindle. The nut will then have to be turned only by a fraction of a rotation to achieve clamping.
Quick release hand knobs, see GN 6336.3.
Steel knurled nuts, see DIN 6303.
