OD: outer diameter. Embedded heat-set nuts are commonly used in manufacturing and construction to create strong, reliable fastenings. They are embedded into a material and secured by melting the surrounding material so it flows around the nut and holds it in place. To use them, select a suitable size and type, drill a matching hole, insert the nut, and heat the surrounding material with a heat gun or another heating device. Allow the material to cool and solidify before attaching fasteners. Always follow the manufacturer's instructions and wear suitable protective equipment, such as gloves and eye protection. Ensure the material is clean and dry, take care not to damage surrounding areas while heating, test the fastening strength before applying heavy loads, and avoid overtightening the fastener.
