Material and build: made from engineering ABS plastic for a firm, lightweight holder that secures nails and screws while you hammer. What it does: holds the nail or screw steady and at the correct angle so you can start and drive fast without risking smashed fingers or bent nails. Compatibility: accepts four common nail diameters — 4 mm, 3 mm, 2 mm, and 1 mm — covering a wide range of small to medium fastening tasks. Who it’s for: suitable for all users — DIYers, homeowners, and anyone who wants to protect their hands when hammering. Particularly helpful for people not comfortable using a hammer. Ease of use and performance: simple to position and release, enabling faster, more accurate hammering and reducing time spent correcting bent nails or missed strikes. Key benefits: Safety: keeps fingers clear of the hammer face. Speed: holds fast so you can start driving nails quickly with one hand. Precision: helps align nails and screws for straighter, cleaner results. Versatility: works with multiple nail sizes and with common screw heads. Practical use scenarios: Hanging picture frames or mirrors: hold small nails securely at eye level without balancing or risking injury. Assembling flat-pack furniture or small wood projects: start screws and nails quickly in tight or awkward positions where two hands aren’t available. Light carpentry and repairs: speed up repetitive tasks like securing trim, molding, or small fixtures while improving alignment and reducing waste. Simple, durable, and practical — designed to protect your hands and make hammering easier and more accurate while accommodating four standard nail sizes.
