Wheel Bolt 8-97017044-2 For ISUZU NPR / 4HG1 / 4HK1 – Heavy Duty Wheel Stud
Product Overview
The wheel bolt carrying OEM number 8-97017044-2 secures the wheel disc to the hub on ISUZU NPR series medium-duty trucks. It is a direct replacement for vehicles powered by the 4HG1 and 4HK1 diesel engines, including NPR 4.8L, NPR HD, NQR, and 700P chassis.
Unlike common passenger car wheel bolts, this unit is engineered for the higher torque demands of commercial trucks. The bolt threads into the hub's threaded holes, clamping the wheel against the brake drum or disc. One stripped or broken wheel bolt compromises safety and can lead to uneven wheel loading, vibration, or complete wheel detachment.

Applications
This ISUZU wheel bolt 8-97017044-2 fits the following vehicle lines:
ISUZU 700P series (North American and Asian markets)
ISUZU Forward / F-Series (selected models with same hub pattern)
ISUZU ELF (Japanese domestic market)
Chevrolet / GMC W3500, W4500, W5500 (rebadged ISUZU, 1990s-2000s)
It is specifically compatible with trucks powered by the 4HG1 (4.3L diesel) and 4HK1 (5.2L common-rail diesel) engines, which share the same front and rear hubs.
Features & Benefits
Precise M22 × 1.5 Thread Form
Threads are rolled - not cut - to maintain grain flow lines and increase fatigue resistance. The fine pitch (1.5 mm) provides better vibration locking than coarse threads, critical for wheels that experience constant road shock.
Heat-Treated to Grade 10.9
The bolt achieves a tensile strength of at least 1,040 MPa, matching or exceeding ISUZU's original requirement. Core hardness between 32 and 39 HRC prevents stretching under repeated torque cycles.
Zinc-Plated Surface with Chromate
The bright or yellow zinc finish blocks rust initiation from road salt, water, and brake fluid. The plated surface maintains thread integrity for years and reduces friction during installation.
Conical 60° Seat Design
The bolt head features a 60-degree taper that matches ISUZU's factory steel wheels. When torqued, the taper wedges into the wheel's tapered hole, centering the wheel automatically.
Direct OEM Replacement
The bolt carries the original ISUZU number 8-97017044-2. No modifications or adapters required - simply remove the damaged bolt and thread in the new one.
Corrosion Resistant for Regional Fleets
Fleets operating in coastal areas or regions with road salt benefit from the zinc-chromate finish that holds up to repeated pressure washing and salt spray.
Advantages
One Bolt Saves an Expensive Hub - Replaces only the damaged component instead of requiring full hub replacement
No Special Tools Required - Standard socket and calibrated torque wrench (400-450 Nm for M22 bolts)
Common Across Multiple ISUZU Models - One part number services NPR, NQR, 700P, and rebadged Chevrolets
Trusted by ISUZU Parts Catalogs - Exact OEM number improves search confidence and compatibility
Quality Control & Verification
Each production batch of wheel bolts undergoes comprehensive testing:
Thread profile inspection - Go/No-go ring gauges for M22 × 1.5
Tensile testing - Random samples pulled to failure (minimum 1,040 MPa)
Salt spray test - ASTM B117 for 72 hours, no red rust allowed
Dimensional check - Digital calipers for precise measurements
Magnetic particle inspection - Surface crack detection
Manufacturing facility holds ISO 9001:2015 certification with batch traceability available.
Packaging & Supply
Individual packaging: Bulk packed in 10-piece poly bags
Standard pack: 50 pieces per inner box; 500 pieces per master export carton
Bolt weight: 0.18 kg each; 9 kg per 50-piece box

Shipping: Air freight for samples; sea freight for bulk orders
Minimum order quantity: 10 pieces (sample order welcome)
Quick Summary
The ISUZU wheel bolt 8-97017044-2 is a grade-10.9, M22 × 1.5, 62 mm long direct replacement for NPR trucks with 4HG1 or 4HK1 engines. It features a 60° conical seat, zinc-plated surface, and heat-treated core. One bolt replaces a stripped unit without changing the entire hub. ISO 9001 manufacturing and batch testing guarantee consistent quality.
Order with confidence: every bolt is thread-gauged and tensile-tested. For fleet managers, buying this single part number covers multiple ISUZU models, simplifying inventory.
