DIN 7967
Self-Locking Counter Nuts PAL
Equivalent Standard: UNI 8835
Metric DIN 7967 Self-Locking Counter Nuts PAL are stamped nuts with internal teeth/barbs that function to grip the threads of a mating bolt/screw. It can be used by itself as a nut to assemble lightweight parts that are not subject to great axial forces. Alternatively it can be used in combination with regular hex nuts to function as a jam nut that when tightened against the primary nut the assembly is firmly secured in place and resists loosening by vibrational forces. Tightening the counter nut against the primary nut cause the internal teeth / barbs of the counter nut to distort and bite into the threads of the bolt, locking both the counter nut and the primary nut into place. BRK Industries offers the following sizes for immediate delivery from stock: Diameters ranging from M4 to M27 and available in A2 and marine grade A4 stainless steel.
