Product Details

This product is a “dedicated matching nut” for high-strength bolts in steel structures. Manufactured strictly according to German standard DIN934, it boasts a high strength rating of Grade 10 and is specifically designed for 10.9S large hexagonal bolts and 10.9 grade hexagonal bolts. Precise strength matching avoids the problem of “strong bolt, weak nut” imbalance. In the connection of steel structure main frames, the strength of the nut directly affects the safety of the entire node. Ordinary Grade 8 nuts are incompatible with 10.9S high-strength bolts, easily leading to cracking and stripping. Grade 10 nuts perfectly solve this problem. The thicker nut increases the bearing area, resulting in even stress distribution after tightening, and resistance to loosening and fatigue. It is an essential component for steel structure main frames and heavy equipment connections, and a core category for traders replenishing their stock. A complete range of specifications are available for immediate shipment, ensuring strong compatibility.
