Beverley Hardware Knob – ¼-20 Imperial – 18 mm Bolt (12 mm Thread) – Used, Vintage

Original Beverley hardware knob/wing bolt from the imperial-thread era. Short 18 mm bolt with 12 mm of threads—perfect for period-correct Beverley/Premier brackets and stand collars that use ¼-20 (20 TPI) screws.

Key Features

• Genuine Beverley vintage knob (chrome head, steel shaft)

• Imperial thread: ¼-20 (20 TPI)—common on Beverley/Premier hardware

• Overall bolt length: ≈18 mm

• Threaded length: ≈12 mm

• Contoured/hand-friendly head for quick tightening

Why it’s useful
The short bolt avoids bottoming out in thin brackets and clamps, making it a tidy replacement where longer screws get in the way or contact the post/tube.
