Bolt 3905853 is a genuine specification fixing used on selected Hiab equipment. It is designed to secure structural or mechanical components where correct grade and fit are essential. Loader cranes operate under high load and constant vibration. Using the correct bolt helps maintain clamping force and prevents movement in key assemblies such as brackets, mounts and pivot points. Worn, stretched or corroded fixings should always be replaced with the correct Hiab part number rather than a generic alternative to ensure safety and reliability. Compatibility Part number 3905853 is fitted to selected Hiab machines. Suitability depends on the crane model and serial number. If you are unsure whether this bolt is correct for your equipment, contact us with the serial number and we will confirm compatibility before you order. Only commonly used parts are listed on our website. We can supply any Hiab parts UK customers require, including specific bolts and fasteners identified by part number. If you cannot find the fixing you need, contact us with the serial number of your crane and details of the part required and we will help identify the correct item.
