Material & Design of Double End Stud 160102130003A112

The double end stud 160102130003A112 is forged from SAE 4140 chromium-molybdenum alloy steel. This material provides excellent hardenability, fatigue resistance, and toughness. The blank is heat-treated to achieve a core hardness of 32-38 HRC, while the thread area is induction hardened to 35-42 HRC for wear resistance.

Both ends of the 160102130003A112 feature rolled threads, which create a work-hardened surface and smooth grain flow. Thread rolling eliminates cutting defects and improves fatigue strength by up to 30% compared to cut threads. The central unthreaded shank is precision ground to a diameter tolerance of ±0.02 mm.

The stud length is engine-specific, typically between 80 mm and 150 mm. Each 160102130003A112 double end stud includes a plain middle section that serves as a wrenching hex or a smooth grip area. The transition radii between the shank and threads are carefully designed to eliminate stress risers.

A zinc flake coating (Geomet or equivalent) is applied to the 160102130003A112 stud, providing 720 hours of salt spray resistance. This coating prevents galvanic corrosion when installed in aluminum engine housings or cast iron components.

Role of 160102130003A112 in SANY Fastening Systems

The double end stud 160102130003A112 is used wherever a permanent threaded anchor is needed. One end is threaded into a blind hole (engine block, gearbox housing, or axle carrier). The other end receives a nut to clamp components such as cylinder heads, bearing caps, or suspension brackets. This design prevents thread wear in the parent material.

In SANY D09 and D12 engines, the 160102130003A112 studs secure the cylinder head to the block. Unlike bolts, studs provide more consistent clamping force and reduce the risk of thread galling in aluminum components. The stud’s controlled thread length ensures proper engagement depth without bottoming out.

Within the SANY drivetrain, these studs attach the transmission bellhousing to the engine adapter plate. Their double-ended design allows easy replacement of nuts without disturbing the stud, simplifying maintenance. Always torque nuts to SANY specifications using a calibrated wrench.

Compatible SANY Equipment for Double End Stud 160102130003A112

The double end stud 160102130003A112 is standard on SANY heavy-duty trucks and off-highway machinery. It is extensively used in SRT series rigid dump trucks: SRT45, SRT55, SRT95, and SRT115. These trucks operate in mining and large construction sites, requiring fasteners with high reliability.

The stud also fits SANY wheel loaders (SW305, SW405, SW435, SW465) and crawler excavators (SY215, SY335, SY395, SY500). In motor graders SMG200 and SMG220, the 160102130003A112 secures the front axle pivot and circle drive housing. For concrete pump trucks and crawler cranes, this stud is used in engine mounting and hydraulic pump attachments.

Engine applications include the SANY D09 8.7L and D12 12.13L four-valve diesels. Use only genuine 160102130003A112 studs to maintain correct thread fit and clamp load. Aftermarket studs often lack proper heat treatment or thread geometry, leading to loosening or breakage.

Proper Installation of Double End Stud 160102130003A112

Before installing the double end stud 160102130003A112, clean the threaded blind hole with a tap to remove debris. Apply a thin layer of anti-seize compound (molybdenum disulfide based) to the stud threads. Hand-start the stud into the hole until finger tight, then use a stud installer tool to tighten to the specified seating torque (typically 30-50 Nm).

Do not overtighten the stud into the blind hole, as this can stretch the stud or crack the housing. The stud should bottom gently or reach the specified thread engagement depth (1.5 to 2 times the thread diameter). After installing the stud, lubricate the nut bearing face and threads before torquing the nut.

When torquing the nut on the 160102130003A112 stud, use a torque wrench and follow a crossing pattern if multiple studs secure a component (e.g., cylinder head). Re-torque after the first heat cycle according to the SANY workshop manual. Never reuse a stud that shows thread damage, corrosion pitting, or evidence of yielding.

Symptoms of a Failing Double End Stud 160102130003A112

A loose or broken double end stud 160102130003A112 can cause serious engine or drivetrain issues. Common symptoms include a persistent knocking sound from the engine valley (loose cylinder head), coolant or oil leakage around the cylinder head gasket, and visible soot or exhaust gases at the head gasket seam.

If a stud breaks, the clamped component may shift, leading to misaligned gears, damaged bearings, or catastrophic engine failure. Inspect studs during any major overhaul. If any stud shows thread galling, corrosion under the nut, or reduced torque retention (nut loosens after a few hours), replace the entire set with genuine 160102130003A112 studs.

Always replace all studs in a joint set – mixing old and new studs leads to uneven clamp load and gasket failure. Use only SANY original parts to ensure proper metallurgy and thread fit.

Quality Assurance & Traceability of 160102130003A112

Every double end stud 160102130003A112 is manufactured in an IATF 16949 certified plant. Production includes raw material spectrographic analysis, hot forging, heat treatment (austenitizing, quenching, tempering), and thread rolling. 100% inspection includes tensile testing, hardness verification (Rockwell C), and magnetic particle inspection for surface cracks.

Thread profile and pitch diameter are checked using optical comparators and thread gauges. Coating thickness is measured with an X-ray fluorescence (XRF) device. Each lot is sampled for salt spray testing to confirm 720 hours of corrosion resistance. A laser-etched batch code on the packaging provides full traceability to heat treat records and raw material certificates.

For bulk orders, a Certificate of Conformance (CoC) is provided, certifying that the studs meet all SANY OEM specifications for material chemistry, hardness, tensile strength, and thread accuracy. Independent audits ensure continuous compliance with ISO 9001:2015.

Field Performance of Genuine SANY Double End Stud

Field data from SANY SRT95 dump trucks operating in Australian iron ore mines shows that genuine 160102130003A112 double end studs maintain clamp load integrity for over 15,000 operating hours. Aftermarket studs often fail prematurely due to improper heat treatment, leading to thread stripping or stress corrosion cracking within 4,000-6,000 hours.

The superior fatigue life of the genuine SANY stud comes from the controlled thread rolling process and induction hardening of the thread roots. Fleet managers report that using genuine 160102130003A112 studs eliminates head gasket failures and reduces unscheduled downtime. Always replace studs when the mating nut shows signs of thread galling.

To maximize service life, follow SANY torque procedures and never exceed the elastic limit of the stud. For extreme vibration applications, use a thread-locking compound (medium strength) on the nut threads. Genuine SANY parts deliver the reliability your heavy equipment demands.
