Three-eye screws for outdoor use with luminous plastic heads What it does: Securely anchors tents and tarps with a three-eye design that accepts multiple guy lines or ropes for stable fastening. Visibility and safety: The luminous plastic head charges from sunlight or artificial light and glows in low light, making stakes easier to see at night and reducing trip hazards. Multi-use: The screw (nail) can also be used for other ground-fix applications where a reliable anchor is needed. Key attributes Function: Ground anchors for tents and outdoor shelters; three-eye holes allow flexible rope routing. Compatibility: Designed for outdoor tents and camping gear; suitable for use with typical guy lines and ropes. Material/Design: Luminous plastic head for night visibility; screw-style shaft for driving into the ground. Performance: Provides stable anchoring across a range of outdoor conditions and improves nighttime safety through passive illumination. Why you need it Prevents stakes from being lost after dark and reduces tripping risks around your campsite. Three-eye design gives more secure and adjustable tie-off points than single-loop stakes. Simple, reliable solution to keep tents and tarps anchored in varied terrain. Practical use scenarios Camping: Use these screws to anchor a family tent at a campsite; luminous heads help you locate guy lines and stakes after dusk. Hiking or fishing trips with an overnight shelter: Secure a lightweight tarp or small tent quickly on uneven ground and spot stakes easily at night. Climbing base camps or beach setups: Fasten multiple lines to one stake for added tension control and nighttime visibility in crowded areas. What to expect in the field Easy to install by screwing into soil; three-eye holes accept common guide ropes. Passive lighting from the luminous head requires exposure to sunlight or light to recharge; no batteries needed. Practical for general outdoor use where stable anchoring and nighttime visibility are important.
