385 Piece Washer Nut & Push on Retainer Assortment

• Washer nuts — integral flanged nuts that distribute load and resist loosening in sheet metal and plastic applications
• Push-on retainers — clip-on fasteners that snap onto studs or posts without threading, for fast panel attachment and removal
• Multiple sizes covering common domestic vehicle applications
• 385 pieces total

• Auto body and collision shops — washer nuts and push-on retainers are among the most commonly consumed fasteners during panel teardown and reassembly
• Fleet maintenance operations — a combined assortment covering both fastener types means less time managing individual part numbers for routine body and trim work
• Dealership technicians — interior and exterior trim removals for audio, electrical, and HVAC repairs regularly require both washer nuts and push-on retainer replacements

Washer nuts are threaded fasteners with an integral flanged base that acts as a built-in washer. The flange distributes clamp load over a larger area and often includes serrations or a locking feature to resist vibration loosening. They're used in sheet metal and plastic applications where a standard hex nut would pull through or require a separate washer.

Push-on retainers (also called speed nuts or push-on speed clips) are non-threaded clip fasteners that snap onto a stud or post with finger pressure and hold a panel in place without any threading. They're designed for panels that need to be removed and reinstalled repeatedly, where a threaded fastener would be too slow and a rivet would be permanent. Push-on retainers are common on door panels, fender liners, and underbody covers.
