The Hobson WR66PMM12 is a natural nylon mudguard washer designed for use with M12 fasteners. Its large 37mm outside diameter spreads the clamping load across a wider surface, helping protect softer materials and finished surfaces from marking or damage.
Manufactured from nylon, the washer offers electrical insulation, low friction and resistance to oils, greases and many chemicals. It is suitable for use as a lightweight, non-corrosive washer, spacer or isolator in HVAC, electrical, mechanical and general fastening applications.
