ripp locke lock washers
the system
ripp look"lock washers have radial rbs on both sides. the pitch angle of the ribs is larger than the thread pitch
plior to assembly
atter assembl
the falowing must apply far locking:b>φ
when the saew ar nut is assembled, the radial ribs of ripp lock" lock washers form-dosedly emboss in the counter-surtace and in the underside of the screw hesd, thereiore. there can only be rela ive movementin the separa fon aap batween screw head and washe,rpp lock is a relable screw lock - even under edreme vibration or dynamic stress.due to their high hardhess , the washers can be used with screws of al property das ses up to 12.9.

m increased contact area makes washers and spring washers unnecessary
rounded locking tbe enable corosion protectian to be largely maintained at thelastening points, since the fastening does not damage the surtace
recuced seting walues for the screws because of coldl woking at the damped materials good tightening characteris tics, excellent reusablity
