  • Not ideal for: Applications requiring non-standard thread sizes or longer threaded connections

Double-ended studs measure 16mm overall and connect 1/4"-20 to 3/8"-16UNC threads. Manufactured from 303 stainless steel for use in industrial, workshop and photographic settings.


Secure cross-thread connections - with double-end 1/4"-20 to 3/8"-16UNC threads

Studs have 1/4"-20 threading on one end and 3/8"-16UNC on the other, with an overall length of 16mm. Threads are cut to standard sizes to match common photographic and furniture fittings.

Directly joining two differently threaded components removes the need for intermediate adapters and keeps assemblies tidy and mechanically stable.

Corrosion-resistant durability - with 303 stainless steel construction

303 stainless steel resists oxidation and corrosion in typical workshop and photographic environments. The material choice reduces risk of rust forming on exposed threads.

Suitable for repeated use and long-term installations where exposure to moisture or handling is expected, helping maintain reliable connections.

Low-profile fit in tight spaces - with compact 16mm overall length

Short overall length keeps the stud low-profile when fitted between components, limiting protrusion. The compact form suits brackets and camera plates with limited clearance.

Easier installation in confined mounts and rigs, reducing the chance of interference with other parts and maintaining a cleaner build.
