The tether or cable passes through the centre hole of the bolt, and the use of seawater epoxy resin AB adhesive to do the potting treatment, which can pass through the watertight shell, cabin, plate and so on.

Aluminium bolts are CNC machined from aluminium alloy with hardened surface treatment and oxidised to black. Stainless steel bolts are new products, made of 316 stainless steel, bright silver body, more beautiful.

The hollow bolts have sealing ring groove and matching sealing nut, both with spanner slot, even in the end cap of dense holes is also easy to install and disassemble.
