No. Use the approved hardware specification for the complete mounting stack. A worn bolt’s measured length does not establish its intended head form, thread, grade or suitability for the replacement assembly.
Distinguish measured hardware from the approved fastener specification
Keep the removed hardware as identification evidence, with photographs of any readable markings and its installed position. Do not assume it was the correct original hardware merely because it was in service. Damage, previous substitutions and changed companion parts can make a physical copy a poor basis for a new order.
The fastener-kit planning guide provides the wider purchasing context. This question concerns the technical identity of the hardware before quantities are calculated. Measure only where useful for comparison, and label those values as observations of the removed part. They should not replace the approved fastener designation.
Identify grip stack, head type, thread and grade using OEM documentation
Retrieve the hardware list and installation reference for the actual plow configuration through the equipment documentation. Confirm the head type, thread specification, grade and other required components from that source. Review the stack that the fastener secures, including the edge, cover or mounting members and specified washers or nuts.
If the replacement edge changes a mounting dimension, have the responsible reviewer determine whether the hardware arrangement remains applicable. Do not simply increase bolt length or reuse an apparently stronger substitute. The correct combination needs a complete fastening review, and this discussion does not prescribe engagement, torque or reuse limits.
Request a complete confirmed hardware list rather than copying a damaged bolt
Ask the supplier to quote the full confirmed hardware list, identifying what is included with the blade and what must be obtained separately. Separate a package-content question from a compatibility claim: a bag of bolts supplied with an edge still needs to correspond to the approved assembly. Resolve missing designations before the installation window.
For a replacement blade order, connect the hardware list to the same equipment configuration and drawing revision as the edge. Receiving inspection should verify identities and quantities rather than merely compare lengths with old bolts. Qualified installers should follow the equipment’s current installation and replacement instructions. Retain the confirmed list for future kits, with any restrictions visible, so subsequent orders do not drift back to copying whichever fastener happens to be removed from a truck.
Primary references support the specific points linked above; equipment documentation applies to its stated models.
