The Trimcraft PA28 Arrow III FAT Wing screw kit is an aircraft maintenance fastener assortment designed specifically for Piper PA-28R Arrow III aircraft with the “fat wing” configuration. It is used to replace exterior airframe screws and washers during maintenance, inspection, repainting, or refurbishment.

These kits typically include a wide selection of corrosion-resistant aviation-grade fasteners used on non-structural airframe areas such as inspection panels, wing fairings, cowlings, access doors, and interior trim components. The goal is to provide a complete replacement set for routine maintenance without needing individual IPC sourcing for each screw.

Based on standard PA28R Arrow III configurations, these kits align with exterior airframe hardware requirements but do not include structural wing attach or load-bearing fasteners.
