Stainless Steel Helical Inserts
Also known as Heli-Coil inserts, these inserts have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.

Threaded Hose Fittings for Hydraulic Fluid
Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system.
Zinc-plated steel fittings are stronger and more durable than stainless steel fittings. They have fair corrosion resistance. Fittings that swivel until tightened rotate for easy installation.
BSPP threads have a gasket or a 60° internal flare to protect against leaks.
