Koah 5/16 in Threaded Speargun Shaft

Overview

The Koah 5/16 in threaded speargun shaft is a replacement shaft for compatible Koah and other compatible spearguns using this shaft standard. Its threaded end accepts a separate spear tip, so both shaft fit and tip-thread compatibility should be confirmed when selecting a replacement.

Construction

Koah starts with larger-diameter 17-4PH stainless steel stock and centerless-grinds it to the finished shaft diameter before machining and heat treatment. The grinding process controls the finished diameter while removing larger surface imperfections and stress points present in the raw stock.

Replacement fit

Match the replacement shaft to the speargun's required diameter, overall shaft length, and tip-thread standard. The required threaded-shaft length is model-specific and does not necessarily match the speargun's nominal size, so confirm sizing from the original shaft or the applicable gun specification before purchase. The spear tip must use the same thread standard as the selected shaft.
