Excavator Bucket Bolt Nut
The Excavator Bucket Bolt And Nut Is Another Common Way To Connect A Bucket To A Stick.Bolts And Nuts Are Usually Arranged At A Certain Distance At The Connection Points Between The Bucket And The Bucket Rod To Ensure The Stability And Load-Bearing Capacity Of The Bucket. They Are Vital To The Proper Functioning Of Excavator Digging, Handling And Loading Operations.
Because Excavators Are Constantly Exposed To Shock And Vibration During Heavy-Duty Work, Bolts And Nuts Can Easily Become Loose Or Damaged. Therefore, Regular Inspection And Tightening Of Bolts And Nuts Are Important Measures To Maintain The Firmness And Safety Of The Bucket Connection.

-Bolt
A Bolt Is A Metal Rod With A Threaded Head And A Threaded Shaft On One End. It Holds The Steel Plates On The Bucket And Stick Together Through Drilling And Progressive Machining.
Bolts Are Usually Made Of High-Strength Alloy Steel To Withstand The Heavy Loads And Impacts That May Occur During Excavator Operation.
A Nut Is A Metal Sleeve With Internal Threads That Is Usually Used With A Bolt. The nut rotates so that its internal threads engage with the bolt's Threads,
Thereby Fixing The Steel Plates Of The Bucket And Stick. Nuts Are Usually Made Of High-Strength Alloy Steel To Ensure The Firmness And Safety Of The Connection.
