Serious anglers and lure makers, these Ruiwaer swivel screw eyes are absolute must-haves for building or repairing your fishing lures! You get 20 pieces of these black alloy copper screws that are built to withstand the punishment of big fish and tough conditions. The swivel action is smooth, allowing your lures to move naturally in the water without twisting your line. The black anti-glare coating is genius - it prevents light reflection that can spook fish in clear water conditions. Installation is straightforward - they work perfectly with D drills, throttling drills, and blowback drills for various lure types. One end inserts securely into pill-shaped baits while the other end features a ring for connecting your hooks and fishing line. The quality is immediately apparent - these aren't flimsy components that will bend or break under pressure. Perfect for crankbaits, pop-up pegs, and various other fishing applications. Having a supply of these on hand means you can quickly repair damaged lures or customize your existing ones for specific fishing situations. Much more cost-effective than replacing entire lures, and often results in better performance than stock components. Seriously improves your tackle box organization and fishing preparedness!
