This GM headlight adjusting screw and nut assembly is designed for headlamp mounting systems that use an adjustable fastener to position the headlight assembly. It provides a replacement for worn, damaged, or missing adjustment hardware encountered during headlight repair, replacement, or aiming service.
The assembly uses a 1/4"-28 screw with a 2" length and includes the corresponding adjusting nut. It cross-references GM OEM numbers 343543, 343555, and 343541 when the original headlight adjuster matches the specified thread size, length, and assembly design.
