OEM 860178246 The XCMG Screw 860178246 is a genuine threaded fastener used to clamp covers, brackets and hydraulic components on XCMG excavators.
Issued under the factory part number 860178246, the screw gives technicians a correctly sized and correctly graded fastener for the joint it closes.
The body is formed from steel, then threaded and heat treated so the shank carries clamp load without stretching or shearing.
Thread pitch, length and head form follow the XCMG drawing, so the screw turns in by hand and seats at the specified torque.
A protective plating resists corrosion, which keeps the thread free and prevents rust bleeding onto painted panels.
Every screw is checked for thread gauge, length, head dimensions and hardness before the batch is packed for shipment.
Used on valve covers, guards, brackets and hose clamps, this screw is a low-cost part that holds critical assemblies together.
The 860178246 screw is made to the XCMG drawing, so the thread, length and head form match the tapped hole or nut it threads into.
Threads are rolled or cut to the OEM class, so the screw starts by hand and pulls down without galling or cross threading.
Correct property class keeps the shank from stretching under full torque, so clamp load stays where the joint design needs it.
Heat treatment gives the head and thread the strength to take repeated assembly without rounding off the hex or socket.
A zinc or oxide finish resists rust, so the thread stays free and the fastener comes out easily at the next service.
Because the part matches the OEM number, a technician fits it straight from the bag and reuses the original torque value.
Correct length prevents the screw from bottoming out in a blind hole, which is a common cause of stripped threads.
A sound fastener keeps covers and guards tight, so oil stays inside and dust stays outside the assembly.
Production starts with certified steel wire or bar, checked for grade, diameter and surface freedom from cracks and laps.
Blanks are cold formed or machined, then threaded and pointed, so the thread runs concentric with the shank axis.
Heat treatment follows the OEM class, giving the screw strength for its torque rating without becoming brittle.
Inspectors check thread gauge, length, head dimensions and hardness on a gauge built for this exact part number.
Batch records trace every 860178246 screw to its steel lot and heat treat run, so a quality question is settled quickly.
A screw turns torque into clamp load, pressing two parts together so the joint does not move under vibration or load.
If a fastener is too soft, it stretches and the joint loosens; if it is too long, it bottoms out and strips the thread.
The genuine 860178246 delivers the clamp load the joint was designed for, so covers, brackets and clamps stay tight.
Correct plating keeps the thread free, so the fastener can be removed at service without drilling or breaking it off.
A sound fastener protects seals, gaskets and mounted components, which keeps maintenance intervals predictable.
The 860178246 screw is fitted with a torque wrench and the correct socket or key during routine service and repair work.
Clean the thread in the hole and check for damage, dirt or old thread lock, since any of these changes the torque reading.
Start the screw by hand to confirm the thread engages cleanly, then run it down with the tool.
Tighten to the torque in the XCMG service data, working in a cross pattern where several fasteners hold the same cover.
Do not over-torque, because excess load stretches the shank or strips the thread and the joint begins to loosen.
After the first running hours, recheck the torque on covers and brackets that see vibration and pressure pulses.
At service intervals, look for rust, rounded heads or oil film around the fastener and renew any damaged screw.
Every 860178246 screw is produced in an ISO 9001 and ISO 14001 certified plant with traceability from wire to carton.
Incoming steel is checked for grade, and finished screws are gauged for thread, length, head size and straightness.
Each batch is inspected for cracks, laps and rolled-in scale, since these defects start fatigue failures under load.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG tapped hole fixture.
Sample screws from each lot undergo proof load and salt spray testing to confirm strength and corrosion performance.
Cheap copies often use soft steel with no heat treatment, so the head rounds off or the shank stretches at rated torque.
A screw with the wrong length or thread pitch can bottom out or engage only a few turns, and both cases damage the joint.
The genuine 860178246 follows the XCMG drawing, so thread, length, head form and strength class match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM assemblies.
Supported by XCMG global quality standards and technical support, this screw performs reliably in harsh conditions.
Choosing the genuine 860178246 screw prevents a small fastener failure from becoming a damaged cover or casting.
A loose cover can let oil escape and dirt enter, which wears the parts underneath and shortens their service life.
A properly plated screw comes out cleanly at the next service, so the thread in the housing is protected for reuse.
Reliable fasteners keep joints tight, which lowers the total cost of ownership for fleet operators and repair shops.
Service records from construction and mining fleets show genuine XCMG hardware reduces unplanned downtime.
XCMG produces the 860178246 screw with efficient forming runs and tight material control that keep production scrap low.
A long service life means fewer replacements, which cuts the steel and energy tied to each fastener.
Tight joints prevent oil and coolant leaks, helping operators meet rules on environmentally sensitive sites.
The steel in this part complies with RoHS and REACH requirements for safe handling and responsible recycling.
The 860178246 screw is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each screw is bagged to protect the thread and plating, then boxed in a strong carton that guards against damp.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps threads clean and heads undamaged until fitting, avoiding the problems seen in loose storage.
The XCMG Screw 860178246 is a small but essential fastener on XCMG excavators, holding covers, brackets and clamps in place.
Its correct thread, strength class and protective plating deliver dependable clamping in hot, wet and dusty conditions.
By keeping joints tight and removable, this screw cuts downtime, protects seals and extends the life of the assembly.
