9KM Swimbait Jig Head Hooks | 5 Pack | 21–42g | 3D Eye Saltwater Jig Heads

The 9KM Swimbait Jig Head Hooks are heavy-duty jig heads designed for pairing with larger paddle tails, jerk shads and other soft plastics for estuary, inshore and offshore fishing.

Available in 21g, 28g, 35g and 42g sizes, these jig heads give anglers the extra weight needed to fish deeper water, stronger current and larger soft plastics effectively.

Each head features a streamlined baitfish-style profile with a 3D eye, while the large single hook provides plenty of clearance for rigging substantial soft plastics. A screw-style bait keeper extends from the rear of the jig head to help secure the soft plastic firmly in position.

Supplied in packs of five, they're a strong option for Australian fishos targeting snapper, mulloway, coral trout, mangrove jack and other larger predators.

Choosing Your Weight

21g: Great for deeper estuary fishing and moderate current where you still want a relatively natural soft-plastic presentation.

28g: A versatile inshore weight for channels, deeper drop-offs and boat fishing.

35g: Provides additional sink rate for deeper water and stronger tidal movement.

42g: The heaviest option for deep water, strong current and heavier offshore soft-plastic fishing.

The right weight will depend on water depth, current, line diameter, soft-plastic size and your rod's recommended lure-weight range.
