M18 Nyloc Nut Type P (Thick) in Bright Zinc Plate Class 8

Prevailing torque type nut manufactured to DIN 982. Hexagon nut incorporating a nylon insert to help prevent loosening when fitted. This is the higher profile (Type P) variant with more available thread engagement and is typically fitted with a spanner or ratchet with socket. A lower profile, where perhaps space is at a premium is also available under DIN 985 (Type T).
