OEM 800169711 The XCMG 3023536 Hex Nut 800169711 is a genuine OEM hex nut engineered to clamp critical bolted joints securely on XCMG hydraulic excavators.
Identified by part number 800169711, this factory-made nut is threaded to exact pitch and class, so it develops full preload without stripping or galling.
It is produced from high-strength carbon or alloy steel, hot-forged or cold-formed, then heat treated and coated for corrosion resistance.
Exact OEM thread size, hex width across flats, and nut height allow direct replacement with standard wrenches and the specified torque.
By holding clamp force steady under vibration, this hex nut keeps structural, hydraulic, and drivetrain joints tight through long working shifts.
The 800169711 Hex Nut is made from high-strength steel that develops full bolt preload without thread stripping or deformation.
Threads are cut or rolled to exact pitch and class, so the nut runs on smoothly by hand and torques without galling.
The hex flats are formed precisely, so standard sockets fit tight without rounding the corners during high-torque tightening.
A zinc or phosphate coating slows rust and galvanic corrosion, which keeps the nut removable after years of outdoor service.
Correct nut height spreads thread load evenly, which reduces stress on the bolt and helps the joint hold torque under vibration.
Exact OEM dimensions allow direct replacement with standard tools, which keeps repairs fast and avoids improvised hardware.
Production starts with certified steel wire or bar checked for chemical composition, hardness, and surface quality before forming.
Forging or cold forming shapes the hex body and head, then tapping or thread rolling creates the internal thread with controlled pitch diameter.
Heat treatment develops the strength and toughness required for high-clamp joints, and coating is applied after cleaning.
Inspectors check thread gauge fit, width across flats, nut height, and coating thickness throughout the production run.
Batch records let XCMG trace each 800169711 nut back to its steel lot and heat-treat batch, so quality questions are resolved quickly.
Excavators generate constant vibration and shock, and every bolted joint relies on the nut to hold clamp force.
A soft or poorly threaded nut can strip under torque, which leaves the bolt loose and allows the joint to fret and crack.
The genuine 800169711 holds its preload under vibration, so brackets, hydraulic mounts, and drive components stay firmly attached.
A correct coating keeps the nut free of rust, so it can be removed during service without cutting or damaging the bolt.
Consistent fasteners across the machine make maintenance predictable, because technicians know each joint will torque correctly.
The 800169711 Hex Nut installs with standard sockets and a torque wrench, adding only minutes to a normal service job.
Park the excavator on flat ground, lower the attachment, release hydraulic pressure, and lock out the machine before work.
Clean the bolt threads and the joint face, and inspect the bolt for stretching or damage before fitting the new nut.
Thread the nut on by hand to confirm a smooth fit, then tighten it in the specified sequence to the workshop manual torque.
After the first working shift, recheck torque, because initial settling can relax the joint slightly.
During scheduled maintenance, replace nuts that are rounded, cracked, or heavily rusted, and never reuse a damaged nut.
Every 800169711 nut is produced in an ISO 9001 and ISO 14001 certified plant with documented material and process control.
Incoming steel is checked for grade and hardness, and finished nuts are gauged for thread fit, hex width, and height.
During production, tap wear and thread dimensions are monitored so drift is corrected before parts leave the line.
Post-production checks include visual inspection, proof load testing, and coating thickness measurement for specification compliance.
Batch samples undergo salt spray and vibration loosening tests to confirm corrosion resistance and clamp stability in the field.
Generic hardware nuts may look similar, but steel grade, thread class, and coating often fall outside the XCMG specification.
A low-grade nut can strip at the specified torque, which damages the bolt and forces a larger repair.
The genuine 800169711 is manufactured to the XCMG drawing, so thread size, strength class, and coating match the original part.
Using genuine XCMG fasteners also preserves warranty coverage, protects resale value, and maintains compatibility with other OEM components.
Backed by XCMG global quality standards and technical support, this hex nut delivers dependable clamping in harsh conditions.
Choosing the genuine 800169711 nut prevents small clamping failures from growing into expensive structural or hydraulic repairs.
A loose nut can let a bracket move, which chafes hoses, misaligns covers, and cracks mounting welds.
Durable steel and proper coating keep clamp force consistent across a long service life, reducing replacement frequency.
Reliable joints also extend bolt, bracket, and panel life, lowering the total cost of ownership for fleet operators.
Maintenance teams using genuine XCMG hardware report fewer rework jobs and fewer torque rechecks after repairs.
Steel nuts are fully recyclable, and XCMG production processes are designed to minimise scrap and energy use.
Because each nut lasts many service cycles, fewer parts are consumed and less packaging waste is generated over time.
Properly torqued joints reduce oil and coolant leaks, which helps protect soil and water on construction sites.
Materials and coatings used in this component meet RoHS and REACH requirements for safe handling and disposal.
The 800169711 Hex Nut is stocked in XCMG regional distribution centres across North America, Europe, Asia, and Australia.
Units are bagged and boxed in moisture-resistant packaging so they arrive clean, dry, and free from coating damage.
Fleet buyers can combine nut orders with other parts in one shipment, which reduces freight and paperwork effort.
Stock visibility tools help planners confirm availability quickly, so service teams are not delayed by missing hardware.
Protected packaging keeps the factory finish intact until the nut is fitted on the machine.
The XCMG 3023536 Hex Nut 800169711 is a small but essential part that keeps bolted joints tight on XCMG excavators.
