The 800167075 S151 Hex Nut is an OEM replacement fastener for XCMG hydraulic excavators. It is used to secure structural and hydraulic connections where a strong, correctly sized nut is required.
This nut is produced from high-strength steel with a protective coating. Its thread pitch, hex profile and load capacity match the original part, so it can replace a worn or lost nut directly.
On an excavator, fasteners are exposed to constant vibration, shock loads and weather. A correct S151 hex nut keeps the joint tight and prevents loosening that could damage the surrounding parts.
The 800167075 nut is suitable for maintenance work, bolt replacement and rebuild projects. It is a practical item to keep in stock for routine service and emergency repair on site.
Common reasons to replace a hex nut include damaged threads, a rounded hex corner, corrosion after long exposure, a lost nut during repair and thread deformation caused by overloading.
Fitting a new 800167075 nut restores correct clamp load at the joint. This protects the bolt, the bracket and the attached component from movement and helps keep the machine working safely.

The S151 hex nut is a load-bearing fastener used across the excavator structure. It works with a matching bolt to clamp two parts together and hold them under vibration and shock.
Because excavators work with constant hydraulic movement, joints must stay tight. A damaged nut can allow the bolt to loosen, which may cause noise, wear or failure of the connected part.
This 800167075 nut is made to the original S151 specification. It offers correct thread engagement, a proper hex profile for standard tools and reliable clamp force.
The part is suitable for scheduled maintenance and for repairs after a bolt has been replaced. Keeping spare nuts available helps reduce downtime when a fastener is found damaged.
The nut is built for strength, correct fit and long service life. The main features are listed below for quick comparison with an original part.
The 800167075 S151 Hex Nut is intended for XCMG hydraulic excavators that use this fastener size in their structure and attachments. It fits the matching bolt and mounting position.
Typical use includes general excavation, trenching, loading, site preparation and utility work. In these jobs, vibration and shock loads demand fasteners that stay tight over long shifts.
The nut also suits maintenance planning for machines working in dusty or wet conditions. Checking fasteners during service helps prevent loose joints and unexpected machine stoppage.
Always confirm the OEM number, thread size and standard before fitting. The 800167075 nut is a direct replacement for the matching position and keeps the joint close to factory specification.
Before work, park the excavator on level ground, lower the attachment to the ground and switch off the engine. Apply the safety lock and allow hot parts to cool before starting.
Remove the old nut and inspect the bolt threads. Clean dirt and rust from the joint, check the bracket faces for damage and replace any bolt that shows stretched or damaged threads.
Thread the new 800167075 nut on by hand, then tighten with the correct socket and torque wrench. Use the workshop torque value for the joint and avoid over-tightening.
After tightening, check that the nut seats fully and the bolt end protrudes correctly. During routine service, inspect the nut for rust, cracks and loosening to keep the joint reliable.
The 800167075 hex nut is produced to match the original dimensions. Thread pitch, hex width and height are checked so the nut fits the intended bolt and tool.
The protective coating helps protect the steel from mud, water and dust. This is important for excavators that work outdoors and are washed or exposed to rain during operation.
Each batch is checked for surface quality, thread condition and overall shape. Batch inspection supports consistent fit and helps reduce installation time in the workshop.
A correct nut protects the bolt and the joint from movement. This supports stable clamp load and helps avoid the noise, wear and failure caused by a loose fastener.
A damaged nut can seem like a small problem, but it can allow a bolt to loosen and cause wear or failure in the joint. Replacing it early is a simple way to protect the machine.
The 800167075 part offers a direct fit, high-strength steel construction and a coated finish. It is designed for the practical demands of XCMG hydraulic excavators in earthmoving work.
For maintenance teams, stocking this nut with other fasteners helps reduce waiting time when a machine needs repair. It supports planned service and quick replacement.
Choose the 800167075 S151 Hex Nut for correct thread fit, dependable clamp load and long service on compatible XCMG excavators. Confirm the OEM number before ordering.
