The hex-head bolt and separate marked nut provide a fastener example. They do not verify 5j4773 or 3f5108 compatibility, selected metric size or mechanical grade for an excavator or grader.

Match the equipment connection drawing

Identify the machine reference, actual mating parts and required head contact. Confirm grip and thread engagement before selecting a replacement configuration.

• Identify equipment model and part reference.
• Define head seat and shank dimensions.
• Specify thread series, pitch and engagement.
• Select matching nut property requirements.
• Agree finish and mechanical acceptance records.

Resolve size and property requirements

M12, M14, M16 and M22 are selection references. Grades 8.8 and 12.9 require the applicable property standard and evidence; the general class menu is not proof of either.

Agree the supplied bolt and nut set

Select actual material and compatible finish from the source options. Confirm dimensions, mechanical checks, quantities and application acceptance; visible nut markings alone do not establish load capacity or machine fit.
