Genuine Mazda Rear Lamp & Bumper Screw Grommet – MX-5 Mk4 / ND • BHN1-50-0Z1A

Genuine Mazda BHN1-50-0Z1A Rear Lamp and Bumper Screw Grommet

Replacement Genuine Mazda plastic screw grommet for Mazda MX-5 Mk4 / ND and RF rear combination-lamp and rear-bumper mounting positions listed in the compatibility table.

The grommet clips into the appropriate body, lamp-support or bumper mounting aperture and provides the captive fixing point for the corresponding screw.

It allows the mounting screw to secure the surrounding component without threading directly into an unprotected body-panel or plastic aperture.

Replacement may be required where the original grommet is missing, cracked, distorted, loose in its aperture or no longer grips the fixing screw correctly.

This listing supplies one individual Genuine Mazda screw grommet. The number required depends on the precise rear-lamp, bumper or trim mounting position being repaired.

Fitment advice: This grommet is used at multiple rear lamp, bumper and associated trim mounting positions on applicable Mazda MX-5 ND and RF models.

Position advice: Because the same grommet is used at several locations, inspect the original fixing and surrounding mounting diagram before ordering the total quantity required.

Quantity advice: This listing is for one grommet. Multiple units may be required when removing a complete rear lamp, bumper or adjoining trim assembly.

Screw advice: The corresponding mounting screw is normally supplied separately. Inspect its thread and head before reuse and replace it if corroded, damaged or incorrectly sized.

Removal advice: Extract the original grommet carefully using a suitable trim tool. Pulling it out at an angle may damage the body aperture or break the plastic fixing.

Aperture advice: Clean the mounting opening and remove loose dirt, corrosion or broken plastic before installing the replacement grommet.

Installation advice: Press the grommet squarely into the correct aperture until its retaining shoulders are fully seated. Do not force it into an opening of the wrong size.

Tightening advice: Start the mounting screw by hand and tighten only sufficiently to secure the component. Excessive tightening can strip or split the plastic grommet.

Lamp advice: When used around a rear combination lamp, inspect the lamp gasket, mounting studs and electrical connector before reassembly.

Bumper advice: When used around the rear bumper, inspect the adjacent guides, brackets, clips and mounting tabs for cracking or distortion.

Water-leak advice: This grommet is primarily a fixing component and should not be relied upon to repair a luggage-compartment water leak. Inspect the lamp gasket, body seams and drainage paths separately.

Other items to consider: Consider inspecting or replacing the corresponding mounting screw, neighbouring grommets, bumper clips, lamp gasket and luggage-compartment trim retainers according to their condition.

Useful tools / consumables: Plastic trim-removal tools, suitable screwdriver, small pick where required, cleaning cloths and electrical-contact cleaner when working around a rear lamp.

Difficulty guide: DIY Difficulty: Easy to moderate. Difficulty depends on whether access requires removal of luggage-compartment trim, a rear lamp or the rear bumper.

Why Genuine Mazda? Genuine Mazda fixing grommets are manufactured to the intended aperture dimensions, screw engagement and retaining profile. Using the correct OE insert helps secure the component without substituting an unsuitable universal fixing.

What’s in the box: One Genuine Mazda plastic screw grommet, part number BHN1-50-0Z1A. Mounting screw, rear lamp, bumper, trim panels and installation tools are not included unless specifically shown or stated separately.

Installation notes: Remove the relevant lamp, bumper or trim component sufficiently to access the fixing. Extract any damaged grommet and clean the mounting aperture. Press the replacement grommet squarely into position until fully seated. Align the adjoining component, start the appropriate screw by hand and tighten it carefully without stripping the plastic insert. Confirm that the lamp, bumper or trim sits securely and evenly before completing reassembly.
