STANLEY STMT77840-23B 24mm 1/2-Inch VDE Socket in Indore

Identify the correct 24 mm socket before ordering

What does 24 mm mean on this product?

The 24 mm dimension is the nominal metric across-flats size of the matching external hexagonal fastener. It does not describe the diameter of the socket body or the ratchet connector. Match the actual nut or bolt head to the socket opening before applying force.

What does 1/2-inch drive mean?

The 1/2-inch (12.7 mm) square drive attaches to a correctly fitting 1/2-inch hand ratchet or suitable insulated hand driver. A 3/8-inch-drive ratchet does not fit this square drive directly. Where insulation is required, use a compatible, appropriately rated insulated drive system; an ordinary adapter should not be assumed to preserve the protection of a complete insulated setup.

Dimensions, material and insulation information

STMT77840-23B product specifications

Why the 60 mm length and outside diameters matter

The stated 60 mm length and 34.5 mm / 27 mm external dimensions help when checking clearance around a 24 mm fastener. A correctly sized hex opening may still be unusable if the insulated body interferes with a nearby flange, guard or housing. Confirm clearance on the actual equipment when space is limited.

Understanding VDE insulation in real work

The product is listed as a VDE socket, with a 1,000 V insulation designation reported by a specialist retailer. Electrical suitability depends on the current markings and condition of the supplied tool, its compatible insulated drive components and the worksite's authorised safety procedures. If purchasing approval requires a manufacturer-issued IEC/VDE certificate specifically for STMT77840-23B, obtain and verify that documentation before use. Insulated tools do not replace isolating equipment or a formal electrical risk assessment.

Suitable fastening and maintenance applications

Where a 24 mm insulated socket may be selected

This socket may be appropriate for suitably sized 24 mm external-hex fasteners during electrical plant, panel equipment, machinery and industrial maintenance where the work procedure specifies insulated hand tooling. Select it by measured fastener size, the approved tool system and available physical clearance—not merely because a work area contains electrical equipment.

Build a compatible insulated tool arrangement

Use the correct 1/2-inch-drive insulated ratchet and, where needed, compatible insulated accessories. Inspect the socket and other tools for cracks, damage or worn insulation and follow the site-specific isolation, testing and personal-protection procedures. Do not assume a normal uninsulated ratchet becomes insulated simply because a VDE socket is attached.

Applications and use claims to avoid

This is not a 24 mm internal-hex bit socket, spark-plug socket or external Torx socket. A powered impact-wrench approval or specific maximum torque rating for STMT77840-23B has not been established here, so select an explicitly suitable tool when an impact-rated application is required.

Comparing sizes and socket types

24 mm versus 21 mm and 22 mm sockets

A 24 mm external-hex fastener needs a corresponding 24 mm socket. Nearby 21 mm and 22 mm sizes should not be substituted: a loose socket risks slipping or damaging the fastener, while an undersized socket cannot seat properly.

Insulated VDE versus an ordinary chrome-vanadium socket

The material description alone does not establish electrical suitability. For ordinary non-electrical fastening, a regular socket may meet the mechanical requirement. Choose this VDE-insulated model only where the specified job, compatible tool assembly and operating procedures justify it, and verify the current product markings.

Is a 24 mm insulated socket the same as a 24 mm impact socket?

No. The product category and intended approval differ. A 1/2-inch square drive is a mechanical connection size, not proof that a socket is impact-rated. Confirm the required operating method before purchasing.

Buying this model for delivery in Indore

Verify the exact SKU and quantity on the national listing

Specify STMT77840-23B when ordering for maintenance schedules, replacement tool inventory or a procurement list. Before checkout, check the current GST-inclusive price, selling unit and total quantity displayed for the same exact model. A competitor's one-piece offer is not proof of Indus MegaMart's packaging.

How stock affects ordering and delivery

Indus MegaMart's ordering policy allows orders and payment even when currently available stock is zero or insufficient. Where the order quantity does not exceed available stock, the stated delivery period is within 7 days. If the order quantity exceeds available stock—including a zero-stock situation—the applicable period is within 7–14 days. Confirm that your Indore delivery pincode is serviceable when placing the order.

Frequently asked questions

1. Is STMT77840-23B a 24 mm or 1/2-inch socket?

Both descriptions apply to different interfaces: 24 mm is the external hex-fastener size, while 1/2 inch is the square drive used to attach the socket to the ratchet.

2. What are the STMT77840-23B overall dimensions?

An exact-SKU specialist listing gives 60 mm overall length, D1 34.5 mm and D2 27 mm. Confirm dimensions against the supplied product if clearance is critical.

3. Can I use this socket with a standard 3/8-inch-drive ratchet?

Not directly. The socket has a 1/2-inch square drive. Use a compatible insulated driver when an insulated tool system is required rather than assuming a regular adapter provides equivalent protection.

4. Is the STMT77840-23B certified for 1,000 V electrical work?

An exact-model retailer lists a 1,000 V insulation designation. This is not, by itself, a manufacturer-issued certificate for your supplied unit. Confirm exact-SKU certification, tool markings, condition and the approved work procedure where formal electrical compliance is required.

5. Is it suitable for an impact wrench?

An exact-model impact-wrench approval has not been verified. Do not use the 1/2-inch square-drive designation as evidence of impact-tool compatibility.

6. How many sockets come in one Indus MegaMart order unit?

Check the current selling-unit and pack information on the exact Indus MegaMart listing before selecting order quantity. A competing retailer's one-piece listing does not confirm this seller's pack size.

7. Can I order if available stock is zero?

Yes. Under Indus MegaMart's order policy, orders and payment are accepted even with zero available stock. When an order exceeds available stock, the stated delivery period is within 7–14 days, subject to destination serviceability.

8. Does the product price include GST?

Verify the current displayed GST-inclusive total and any line-item tax breakdown on the exact product page before paying. Indus MegaMart-generated invoices include the company's GST number.

9. Can the socket be delivered to a Indore address?

Use the exact product listing to check serviceability for the intended Indore pincode and review the applicable delivery period. A Indore-targeted product page does not mean the product is stored in a Indore warehouse.

10. Should I choose 24 mm instead of 22 mm for my fastener?

Use 24 mm only for a matching 24 mm external hex head. Measure the fastener before ordering; a 22 mm socket is not a substitute for a 24 mm head.
