It is supplied as a genuine branded SKU for replacement, tool kit standardization, and repeat MRO procurement across India.
STANLEY STMT72884-8B Application Context & Use Cases
This socket is typically used in:
- Automotive service bays for 13mm hex fasteners
- Two-wheeler and passenger vehicle maintenance
- Industrial MRO teams handling metric bolt assemblies
- Equipment panel fastening
- Light machinery assembly lines
- Maintenance shutdown tool replenishment
It is appropriate where:
- Controlled torque application is required
- Access space supports standard socket length
- Fastener head condition requires 6-point engagement
It is not intended for impact wrench use unless specifically paired with impact-rated accessories.
Selection Guidance – How to Choose Correctly
Confirm Drive Size Before Ordering
A 1/4" drive socket fits only 1/4" drive ratchets, extensions, or torque tools.
Common confusion:
- 1/4" drive ≠ 1/4" fastener size
- 1/4" refers to drive interface, not bolt diameter
If your ratchet is 3/8", this socket will not fit without an adapter.
Choose 6-Point vs 12-Point Correctly
6-point sockets:
- Provide stronger contact on flat surfaces
- Reduce risk of fastener rounding
- Preferred for tight or high-load fastening
12-point sockets:
- Easier alignment in confined spaces
- Slightly reduced contact area
For workshop durability, 6-point is generally selected.
Confirm Metric Requirement
13mm is metric.
It is not interchangeable with similar SAE sizes.
Incorrect size selection may cause:
- Fastener head damage
- Torque misapplication
- Slippage
Capacity / Practical Torque Logic Example
A 1/4" drive socket is typically used for light to moderate torque applications.
Example scenario:
If tightening a 13mm bolt on a two-wheeler engine casing:
- Recommended torque range may fall within light torque brackets
- 1/4" drive ratchet provides controlled leverage
- Reduced risk of overtightening compared to larger drive sizes
Using a 3/8" or 1/2" drive in the same scenario may increase risk of thread stripping.
Drive selection should match torque requirement, not only bolt head size.
Failure Conditions & Misuse Risks
This socket may fail or underperform under the following conditions:
- Use with impact wrench (non-impact rated)
- Application of excessive torque beyond drive design
- Use on rounded or deformed fasteners
- Corrosive chemical exposure without cleaning
- Hammering or side-loading
Typical misuse damage:
- Chrome flaking
- Drive deformation
- Internal rounding
For heavy industrial torque or seized fasteners, impact-rated sockets should be selected instead.
Who Should NOT Buy This
This socket is not suitable for:
- Impact wrench operations
- High-torque heavy industrial bolting
- Structural steel erection
- Applications requiring deep-reach access (choose deep socket)
- SAE fastener systems
If torque demand exceeds light-to-moderate fastening, upgrade drive size accordingly.

- Avoid angular loading
- Store in dry tool tray
During repetitive use:
- Inspect for internal rounding
- Check chrome surface integrity
- Replace if grip loosens

Selection Checklist
Before placing order, confirm:
• Ratchet drive is 1/4"
• Fastener size is 13mm metric
• Application does not require impact rating
• Standard depth is sufficient
• Torque requirement within light-to-moderate range
• Quantity requirement clearly defined
• Delivery location confirmed
If all above are validated, this SKU is appropriate.
High-Intent FAQs
Q1. Is this socket suitable for impact wrench use?
No. It is designed for manual ratchet use. Impact applications require impact-rated sockets.
Q2. Can this be used with a 3/8" ratchet?
Only with a 3/8" to 1/4" adapter. Direct compatibility is not available.
Q3. Is this socket deep or standard length?
This SKU is standard length. For extended reach, a deep socket variant is required.
Q4. Is it compatible with torque wrenches?
Yes, if the torque wrench has a 1/4" drive interface and torque range aligns with application.
Q5. Can bulk quantities be supplied for workshops?
Yes. Quantity requirements should be specified at enquiry stage for dispatch planning.
Q6. Is GST invoice provided?
Yes. GST-compliant billing is supported for institutional buyers.
