Each 160102130003A006 Hexagon Screw Plug is documented in the SANY Engine Block Group parts catalog as a critical fastening and sealing element. Within this assembly, the plug works in conjunction with Washer, Seal components, O-ring fittings, and Hexagon Flange Bolts to ensure complete leak-free integrity of high-pressure oil and coolant passages essential for reliable engine operation.

The plug is manufactured from high-grade steel with precise thread dimensions conforming to international standards. The threads are carefully rolled rather than cut, producing a smoother surface finish with improved fatigue resistance and more consistent torque-tension characteristics. This rolled thread process also work-hardens the thread flanks, increasing resistance to galling and thread deformation during repeated installation cycles.

The 160102130003A006 Hexagon Screw Plug is designed to interface with specific associated components identified within the SANY Engine Block Group parts catalog. As documented in catalog reference L2603001, the plug is installed in sequence with an Assembled Sealing Washer (Part No. 160102130003A007), which provides the primary fluid-sealing interface between the plug collar and the engine block mating surface.

Together with Pin, Dowel components (Part No. 61000764) that maintain precise alignment of critical elements, and high-strength Hexagon Flange Bolt (Part No. 160102130003A005) torque-rated joints, this hexagon screw plug forms a critical fastening subassembly. The combination of these components ensures distribution of clamping loads while maintaining fluid containment integrity under thermal expansion and vibration.

In typical SANY engine block applications, the 160102130003A006 plug is installed in galleries such as oil supply passages, water jacket access ports, and machining core holes. The plug’s hexagon recess is oriented outward for wrench access, while the collar seats against the assembled sealing washer. Thread sealing compound or a pre-applied sealing patch is often recommended on the plug threads to fill micro-gaps and prevent fluid migration along the thread helix. For hydraulic manifold applications, the plug may be installed with an O-ring (Part No. 160102120008A001) seated in an undercut groove to provide the primary seal, with the plug threads providing clamping force only.

When the plug is torqued to specification, the sealing washer or O-ring compresses, filling all microscopic irregularities on the mating surfaces. The hexagon screw plug design ensures that installation torque is applied purely in rotation, with no axial or side loading of the sealing element. This pure torque application extends the life of the sealing elements and provides consistent, repeatable results across multiple installations.

When reinstalling, the associated Assembled Sealing Washer (Part No. 160102130003A007) should be replaced to ensure leak-free service. For service professionals, always cross-reference the OEM number 160102130003A006 with the SANY parts catalog to verify exact application and ensure correct thread match with the specific engine or equipment serial number range.

Thread cleaning: Before installing the 160102130003A006 plug, clean both the plug threads and the port threads. Remove all old sealant, debris, and contamination. Use a thread-cleaning tap and solvent-safe brush to ensure a clean, dry surface.

Visual inspection: Inspect the new plug for defects such as thread damage, corrosion, or drive recess deformation. Verify the hexagon socket is clean and undamaged. Do not use a plug with damaged threads or drive recess.

Thread sealant application: Apply a thin, even coat of thread sealant (e.g., Loctite 567) to the first three to four threads, leaving the first thread closest to the tip dry to prevent sealant from entering the fluid system. If using a pre-applied sealing patch, no additional sealant is required.

Torque application: Hand-start the plug into the port to avoid cross-threading. Once finger-tight, use a calibrated torque wrench with a clean hex bit. The recommended final torque range is 25–35 Nm for the typical M14 x 1.5 thread size used with this plug. Always confirm torque requirements in the specific SANY service manual.

Post-installation verification: Allow sealant to cure per the manufacturer’s recommendations before pressurizing the fluid system. Pressurize the system to normal operating pressure and inspect the sealing point for leakage. Run the engine through a thermal cycle and reinspect after cooling.

Inspection intervals: During routine preventive maintenance, visually inspect accessible plug sealing points for leakage, corrosion, or torque retention. For severe-duty applications (mining, coastal), increase inspection frequency. SANY recommends replacement of all non-metallic sealing components associated with this plug at major engine overhaul intervals.

The 160102130003A006 Hexagon Screw Plug has undergone extensive validation testing to ensure exceptional sealing durability under the demanding operating conditions encountered in SANY heavy equipment applications.
