Large Bolt
Large bolt — a bolt with thread diameter over M48. Used in machine building, bridge construction, and metal structures.
Made of steel, property classes: 4.8, 5.8, 8.8, 10.9. Versions with UNC and UNF threads are available. Coatings: electroplated zinc, hot-dip zinc, and others.
The bolts have high strength and reliability, withstand heavy loads, resist vibration, and have anti-corrosive properties. They have high antifriction properties — low adhesion tendency when operating in a lubricated environment, under friction and sliding. Resistant to aggressive media, seawater, acids, and solutions.
One of the common types is the bolt per GOST 10602-94.
FLOK supplies large-diameter bolts.
