Ocean Threaded Shaft

Threaded Ocean Shaft in 17.4 PH Steel for Speargun and Roller Speargun

The Threaded Ocean Shaft is made from 17.4 PH steel, a high-quality material that ensures exceptional stiffness, strength, and an excellent surface finish. This shaft is suitable for both traditional Speargun models and Roller Speargun models, offering a versatile and durable product for spearfishing and freediving.

Technical Features

• Available in two diameters: 7.00 mm and 8.00 mm
• Lengths ranging from 95 cm to 170 cm
• 17.4 PH steel bars, ground, certified, and smooth to ensure maximum accuracy and glide
• CNC-machined production for consistency and tight tolerances

Shark Fin and Bridge Configuration

The shark fins are manufactured with precision-angled profiles, optimized for use with Dyneema and other wishbone materials. They are positioned at 60 mm, 90 mm, 120 mm, and 360 mm from the rear of the shaft to ensure stability and a straight trajectory.

The bridge, made from AISI 316 stainless steel, is fixed at 375 mm from the rear of the shaft, immediately in front of the shark fins. Unlike versions with a D.2 mm hole, this model features a line passage with a height of 2.1 mm and a length of 8.00 mm, compatible with larger-diameter shooting lines and monofilaments for a stronger connection to prongs, spear tips, and slip-tips.

The shark fins include a central hole that facilitates hole shots, improving efficiency and control while spearfishing.

Configurations and Customization

• Number of shark fins configurable upon request
• Shark fin position customizable to suit the freediver’s specific needs
• Choice between drilled or solid shark fins according to technical preferences

Custom options are available with dedicated quotes, offering the possibility to optimize the shaft for different spearfishing techniques.
