     What are the specifications of high-strength nuts? There are many specifications for high-strength nuts used in curtain wall construction, which can be summarized into several key points: Today, we'll share some information we know about high-strength nuts used in construction. 1. Before installing pre-embedded bolts and high-strength nuts, technicians should report in detail to the construction team, checking the specifications, quantity, and diameter of the bolts and high-strength nuts. 2. When pouring concrete, the vibrator must not collide with the fixing frame, and the concrete must not press against the bolts and high-strength nuts. 3. After the concrete pouring is completed, the actual value and deviation of the bolts should be remeasured promptly and recorded. Adjustments should be made if the deviation exceeds the allowable limit until the design requirements are met. 4. To prevent contamination or corrosion, cover the nuts of the anchor bolts with oil or other materials before and after concrete pouring. 5. Bolts and high-strength nuts must be inspected and accepted by the supervisor and quality personnel before concrete pouring. Concrete can only be poured after confirmation of their qualification and signature.
