Stainless Steel Adapter: [ 3/8" OD , 7mm-1 MALE x 5/16"-24 FEMALE ]

Price : $7.50

The 3/8" diameter adapters are typically used on Speargun shafts to mate up different manufacturer spear tip products.


Below is a picture comparing Thread Sizes, note the thread pitch and diameter differences. Those out there calling an 8mm thread the same as a 5/16" thread, this should clarify how wrong this thought is.

Did you know that there are 5 different 8mm sizes with different pitches?
