STANLEY STMT94030-8 Cross Wrench (17, 19, 21, 23 mm)

The STANLEY STMT94030-8 cross wrench provides multi-size wheel nut access for efficient manual tightening and removal in automotive service operations.

STANLEY STMT94030-8 Application & Use

Workshop & Fleet Maintenance Use

The STMT94030-8 cross wrench is typically deployed in:

• Automotive service workshops
• Tyre alignment and puncture repair centers
• Fleet maintenance yards
• Dealership service bays
• Roadside assistance units
• Institutional vehicle garages

Its four-way design allows rapid switching between common wheel nut sizes without changing tools.
Operational Environment
Suitable for:

• Passenger vehicles
• SUVs
• Light commercial vehicles
• Utility vehicles using standard hex wheel nuts

Not designed for high-torque truck wheel applications requiring extended leverage or torque multipliers.

Selection Guidance – How to Choose Correctly

Step 1 – Confirm Wheel Nut Sizes
Verify the vehicle fleet uses hex sizes within:

• 17 mm
• 19 mm
• 21 mm
• 23 mm

If your fleet includes mixed vehicles within these sizes, this model reduces tool duplication.

Step 2 – Confirm Torque Requirement
This wrench is suitable for:

• Standard manual tightening
• Routine tyre change operations
• Non-impact applications

If wheel nuts are over-tightened using pneumatic guns beyond manual breakaway capability, a breaker bar may be required first.

Step 3 – Usage Frequency Assessment
For:

• Daily workshop use → Suitable
• Emergency roadside kit → Suitable
• Heavy truck operations → Not recommended

Capacity / Calculation Example

Manual Torque Application Logic
Torque (Nm) = Force (N) × Lever Length (m)
Example:
If a technician applies 250 N of force on a 0.35 m arm:
Torque = 250 × 0.35 = 87.5 Nm
Typical passenger vehicle torque range: 80–120 Nm
This tool is structurally aligned with manual torque levels for passenger and light commercial vehicles.
Exceeding this via extension pipes or hammering increases weld stress risk.

Failure Conditions & Misuse Risks

Common Misuse Scenarios

• Using pipe extensions for additional leverage
• Hammer impact use
• Applying on damaged or rounded wheel nuts
• Using on truck-grade high torque applications
• Exposure to corrosive chemical environments without maintenance

Structural Risk Points

• Excess torque at welded hub
• Socket rounding due to mismatched nut size
• Coating wear under abrasive use

Proper size matching eliminates premature wear.

High-Intent FAQs

1. Is this product supplied as genuine STANLEY stock?
Yes. Only genuine branded supply is processed. Stock confirmation is provided before order finalization.
2. Can it handle tight wheel nuts loosened by impact guns?
If impact guns have over-tightened beyond manual torque range, initial loosening may require a breaker bar.
3. Is bulk supply available across multiple states?
Yes. Pan-India dispatch capability is available with consolidated logistics handling.
4. What is the typical dispatch timeline?
Standard dispatch is within 1–3 working days subject to stock confirmation.
5. Is there any warranty documentation?
Warranty terms follow brand policy. Commercial invoice provided for records.
6. Can this be quoted for institutional purchase orders?
Yes. Model-level clarity and GST-compliant billing support institutional procurement.
7. Is the wrench suitable for torque-certified tightening?

No. Final torque-critical tightening should use calibrated torque wrench equipment.
