Package contents: 20 metal tent stakes for inflatables and 1 piece of 0.51 inch diameter hex head driver. Stakes are about 12 inch (30 cm) long, thread portion about 8 inch (20 cm) long, and diameter about 0.31 inch (0.8 cm). The light-up top helps you see the stakes at night and can reduce loss. Safe for use: stakes have sufficient strength under windy conditions and are suitable for grass, dirt, and harder soils. They are not recommended for sandy soil. Includes pointed tips; wear tool gloves to avoid injury during use. Material and durability: ground stakes are made of carbon steel and plastic, reliable and reusable, rustproof and sturdy for long-lasting use. The top of each stake glows brightly in the dark after brief exposure to light, aiding visibility. Convenient and practical: stakes have pointed tips that are easy to insert into hard soil, and a spiral design for a stronger grip. With a cordless drill or impact driver, they secure tents, canopies, awnings, or tarps more stably. Use scenarios: - Setting up a camping tent on grass or dirt in windy conditions. - Securing outdoor inflatables or banners at events to prevent movement. - Anchoring backyard canopies or tarps for family gatherings or backyard parties.
