The nylon insert deforms around the thread under torque, resisting loosening caused by vibration - a common issue on off-road vehicles subject to sustained mechanical stress. Using the correct thread form (UNF - Unified National Fine) is essential, as substituting UNC or metric equivalents will result in cross-threading or inadequate clamping force.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1\/4 UNF thread form - Unified National Fine, not to be confused with metric or UNC equivalents\u003c\/li\u003e\n\u003cli\u003eBright zinc plated (BZP) finish provides basic corrosion resistance suitable for general body and chassis fixing applications\u003c\/li\u003e\n\u003cli\u003eNylon insert provides vibration-resistant locking without thread damage, allowing removal and refitting during servicing\u003c\/li\u003e\n\u003cli\u003eSold individually - check quantity required before ordering, and inspect mating bolts for thread condition when replacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 1 (1989–1998), Range Rover Classic, Defender 90, Defender 110, and Defender 130 (1983–2006) across all engine variants, for general fixings applications.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
