Solid Brass Spade Head Thumb Screw M4 8mm Nickel Plated for Vintage Lamp Socket Repair

This solid brass spade head thumb screw features M4 metric thread and an 8mm threaded shank, finished with uniform nickel plating and purpose-built for vintage lamp socket restoration projects. Machined from dense solid brass rather than brass alloy blends, it retains the soft, workable nature and classic metallic character ideal for antique lighting hardware refurbishment. Its dual-wing spade head forms an ergonomic grip surface, enabling users to twist, fasten and release the screw fully by hand without screwdrivers. The accurately formed M4 thread runs along the short 8mm shank, engineered to mate cleanly with original tapped holes inside old lamp bases and ceramic lamp sockets. The nickel plating wraps evenly over the brass substrate, forming a tough barrier that slows brass tarnishing and patina build-up while preserving a refined muted metallic look compatible with retro lamp styling. The thin plating avoids thread binding and maintains precise fit with aged original lamp hardware.
