A38 - 3-8"-16 Threaded Insert for ProMediaGear Clamps

Solid strong ProMediaGear Arca-Swiss quick release clamps on all my tripods and two monopods. This 3/8”-16 bushing should be included along with the 1/4” that comes with the clamp. I for one would rather pay the extra $5-$7.00 and have the option for both. Not a huge inconvenience to order the 3/8” separately, but just another something else to do. Otherwise would have given 5 stars. Nothing beats ProMediaGear as to quality by every metric.

Required to adapt to a 3/8 thread. Hardened steel and fits perfect in the ProMedia clamp, I wish they would package it with the clamp in case the user requires it, a few dollars extra for the versatility when needed vs paying more later.

Well machined, fit perfectly. What I like most about PMG Clamps is the SS inserts that provide an extra strong foundation for my equipment.

I must admit I have not used this product extensively but when I have it is well made and a pleasure to work with.

These pieces are required for the clamp to fasten to anything. I got the clamp pair, but it only came with one insert of each size. So I got spare inserts of each size. They are a bit expensive for what looks about like a big nut, but they're made in USA. The quality seems about as good as the clamps, which is to say superlative. These inserts fit the clamp like they were made for it, which I guess they were. Anyway you might want to get a spare before you absolutely have to, the clamps are almost useless without them. I like the flexibility of two sizes, and these steel inserts seem way less likely to strip out during use than just aluminum.
