Gardner Covert Swivel Bait Screws are an awesome alternative to the original Covert Flexi Bait Screws. The inclusion of a hook swivel instead of a simple rig ring, allows the hook bait more rotational free movement and controlled separation of hook and hook bait. This helps to ensure that rigs incorporating these components work to their maximum potential.
They are available in three sizes:
The Mini Swivel Bait Screw has a 5mm long screw thread (measured from the point to outside face of screw loop). These are perfect for use with small pop up hook baits and ‘cork balled’ hook baits, in which the boilie skin rarely exceeds 2-3mm.
The Standard Swivel Bait Screw has a 7.5mm thread, and these are ideal for slightly larger hook baits.
The Long Swivel Bait Screw has an 11mm thread, and consequently offers the highest possible grip to your chosen hook bait, and is the one to choose with BIG hook baits.
