Jiangxin Time: Shoulder Bolts of different diameters and strengths

Shoulder Bolts

Shoulder bolts play an important role in mechanical equipment and structural connections. Shoulder bolts of different diameters are suitable for various applications from light to extra large mechanical equipment. Depending on the strength grade, shoulder bolts can meet the connection requirements from medium strength to ultra-high strength. Among them, grade 12.9 shoulder bolts are demonstrated in heavy-duty and demanding applications with their high strength, excellent toughness and fatigue resistance. provide significant advantages.
