{"product_id":"m8-locknuts-bzp","title":"M8 Locknuts Bzp for Discovery 1 (1989 – 1998) – NT108041L","description":"\u003cp\u003eM8 BZP (bright zinc plated) locknuts are prevailing torque fasteners used throughout Land Rover chassis, suspension, and body fixings where vibration resistance is required to prevent loosening under load. The nylon insert within the locknut deforms around the thread on installation, maintaining clamping force without relying solely on friction. Using the correct M8 specification ensures proper thread engagement and torque retention - undersized or non-locking substitutes can back off progressively, causing component loosening or failure.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eM8 metric thread specification with bright zinc plated (BZP) corrosion-resistant finish\u003c\/li\u003e\n\u003cli\u003ePrevailing torque nylon insert design prevents self-loosening under vibration\u003c\/li\u003e\n\u003cli\u003eSupplied to OEM specification as part number NT108041L\u003c\/li\u003e\n\u003cli\u003eLocknuts are single-use fasteners - nylon insert loses effectiveness if reused; replace whenever disturbed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 1 (1989–1998), Freelander 1, Range Rover Classic, Defender 90 (1983–2006), Defender 110 (1983–2006), and Defender 130 (1983–2006) across all engine variants where M8 fixings are specified.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
