1 1/2" Brass Knurled Lock Nut 1/4 IPS Lamp Pipe Thread Lighting Hardware NOS
The 1/4 IPS Knurled Lock Nut That Holds the Whole Assembly Together
A brass knurled lock nut is a small part with a firm job. This one is solid unfinished brass, 1 1/2 inches in diameter, threaded 1/4 IPS to fit standard lamp pipe on floor lamps, table lamps, pendants, torchieres, and wall sconces. The wide diameter spreads pressure cleanly across canopies, shade risers, and decorative caps. The knurled edge seats by hand. The unfinished brass takes a polish, a patina, a lacquer, or an antique finish — whatever the restoration calls for.
