Kupo KS-064 Female 1/4"-20 to Male 3/8"-16 Thread Adapter — Convert 3/8"-16 Female Threads to 1/4"-20 with 1.18in Flange

The Kupo KS-064 is a female 1/4"-20 to male 3/8"-16 thread adapter with a 1.18" flange. Also known as a reducing bushing, it lets you convert a 3/8"-16 female thread into a 1/4"-20 female thread quickly and securely. This simple adapter helps you adapt hardware without changing the original mounting points.

Key features and uses

• Converts a 3/8"-16 female thread to a 1/4"-20 female thread, allowing use of smaller threaded accessories.
• Known as a reducing bushing, it provides a compact and reliable mechanical interface between two common thread standards.
• Works well with lights and cameras when you need to fit equipment on a smaller thread, so you can mount cameras or accessories designed for 1/4"-20 onto supports or heads with 3/8"-16 female mounts.

Practical benefits

When you work on set or in the studio, this adapter saves time. Instead of swapping plates or buying new mounts, you screw the male 3/8"-16 into the existing 3/8" female socket and then attach your 1/4"-20 screw-mounted accessory to the adapter's female side. In short, it provides a straightforward way to bridge two widely used thread sizes.

FAQ

Question: Will this adapter let me attach a camera with a 1/4"-20 mounting screw to a support that has a 3/8"-16 female socket?
Answer: Yes. The male 3/8"-16 side screws into the existing 3/8"-16 female socket, and the female 1/4"-20 side accepts the camera's 1/4"-20 screw thread, enabling the connection.

Question: Can I use this with lighting equipment?
Answer: Yes. The adapter is suitable for lights and cameras when you need to fit gear with a smaller 1/4"-20 thread onto a larger 3/8"-16 mount, providing a straightforward mechanical conversion.

Question: Is this adapter the same as a reducing bushing?
Answer: Yes. The product is also described as a reducing bushing because it reduces a larger female thread down to a smaller female thread via the male portion that fits the larger socket.

Question: How do I install the adapter?
Answer: Thread the male 3/8"-16 into the 3/8" female mount until secure, then attach your accessory to the 1/4"-20 female thread. The process is simple and does not require additional tools in most cases.
