Spherical Washers According to the Old Standard DIN 6319, Steel, with Blue PTFE Coating, Type C

Volume Discount

Material: Steel, bright turned, case hardened, hardening depth min. 0.2 mm. With blue PTFE coating.
The very low friction enables precise adjusting at high wear resistance.
Spherical washers according to the old standard DIN 6319 type C are mostly used with conical seats DIN 6319 type D, for screw fittings at non-parallel faces. Conical seats DIN 6319 type G, with larger outside diameter and height, should be used at relatively big holes or slot holes.
