Product description "Hyper-Grip" N52 Neodymium Core: Catch screws instantly. We upgraded the internal magnet to industrial-grade N52 Rare Earth Neodymium. Unlike weak generic rings that let screws drop, this "Hyper-Grip" system provides 10x Magnetic Force, allowing you to hold heavy decking screws or long drywall screws horizontally without them falling off. "Impact-Shield" All-Metal Construction: Built for torque. Stop buying fragile tools. Crafted from premium S2 Alloy Steel / Aluminum (verify your material), this ring resists high-impact shock and abrasion. [Warning: Not Cheap Plastic]. It withstands the rigorous vibration of power drills and impact drivers without cracking or deforming like inferior plastic knockoffs. "Anti-Wobble" Concentric Fit: Drive straighter. Designed specifically for standard 1/4" (6.35mm) Hex Bits. The precision-machined inner bore ensures a tight, concentric fit that reduces bit wobble. It stabilizes the screw the moment it touches the bit, preventing "Cam-Out" (slipping) and protecting both the screw head and your work surface from damage. "Snap-On" Universal Compatibility: Instant upgrade. No tools required. Simply slide the ring onto your hex bit for immediate magnetization. It acts as a powerful Screw Catcher for tight spaces where you can't use your other hand to hold the screw. Ideal for cabinetry, dryway, and automotive repair.
