STANLEY STMT77818-23B 18mm 3/8-Inch VDE Socket in Goa

Order the 18 mm VDE Socket for Goa Delivery

Confirm the right product and the quantity

Choose model STMT77818-23B when your fastening requirement is an 18 mm external hexagon and your insulated ratchet or compatible tool has a 3/8-inch square drive. The millimetre size describes the nut or bolt head; the inch measurement describes the tool connection. The selling unit is not stated unambiguously in the available product listing. Confirm how many sockets are supplied per selected order quantity before completing checkout, particularly for maintenance-kit or project procurement.

Check the current price including GST

The national product listing displays the current price with a GST breakdown. Review the offer's GST-inclusive total, the number of sockets supplied and any order quantities together; do not compare a one-piece quote against a multipiece offer without adjusting the quantity. Purchase invoices include the company's GST number.

Check your Goa pincode and delivery conditions

Use the delivery-pincode check on the product listing for your actual Goa address. Indus MegaMart accepts orders and payment even when available stock is zero. When your ordered quantity is within available stock, the stated delivery window is within 7 days; when the quantity exceeds available stock—including zero stock—the window is 7–14 days. Confirm the destination-specific details at checkout rather than assuming a nearby warehouse or immediate dispatch.

What the dimensions mean before you order

The 45 mm overall length helps assess reach and physical clearance; the D1 28.7 mm and D2 23 mm figures are labelled dimensions in the seller-hosted technical chart. Check the drawing and the available space around the actual fastener rather than assuming these are interchangeable measurement points. This 18 mm socket is not interchangeable with a 17 mm or 19 mm socket, even if the drive size matches.

Understanding the 1,000 V insulation designation

The product chart identifies a 1,000 V insulation designation. This describes the listed tool design; it is not permission to touch live conductors or bypass electrical safety procedures. Exact-SKU certification documents, permitted operating conditions and the condition of the complete tool assembly should be checked with the appropriate manufacturer or qualified safety team before any task where electrical exposure is possible.

Applications and Selection in Electrical Maintenance

Panel and switchgear hardware

For a panel, distribution assembly or switchgear maintenance task that uses a correctly sized 18 mm hexagonal fastener, this socket can be considered where an insulated 3/8-inch hand-tool system is specified. First confirm the fastener itself, access clearance, approved torque, isolation arrangements and the site's safe-work procedure.

Maintenance-kit and project procurement

Electrical maintenance teams assembling a controlled set of insulated tools may need the same 18 mm size across multiple service locations. The product model, correct drive size, insulation status and verified ordered quantity are more useful procurement identifiers than a generic description such as “electrical socket.” For Goa-based purchases, check the actual destination pincode and order unit with the supplier before finalizing quantities.

Why ordinary sockets are not a substitute

A conventional uninsulated chrome socket may fit the same 18 mm fastener but does not provide the same insulation-related product design. Conversely, an insulated socket attached to a non-insulated handle does not make the overall tool assembly electrically insulated. Choose the complete appropriate tool system for the job rather than relying on the socket in isolation.

Compatibility, Limits and Safe Handling

Fitment checklist

Confirm all of the following: the fastener has an 18 mm external hex head; the handle or extension uses a compatible 3/8-inch square drive; the tool has adequate clearance around the fastener; and the selected equipment matches the task's torque and electrical-safety requirements. A 3/8-inch drive must not be mistaken for a 3/8-inch fastener head.

Inspect insulation before use

Check the tool for cuts, cracks, damaged protective layers, contamination, wear or other signs that could compromise insulation. Do not rely on a damaged socket. Use trained personnel and the applicable electrical isolation, testing, PPE and risk-control procedures. The chart's voltage designation does not replace those controls.

Do not infer impact-wrench compatibility

The sources inspected identify this as a VDE insulated socket, not as an impact-rated socket. Do not assume suitability for powered impact wrenches or a particular torque limit without specific manufacturer confirmation. This distinction matters when standard impact sockets and insulated hand-tool sockets appear together in a broad socket catalogue.

Choosing the Right Socket Before Purchase

18 mm versus nearby sizes

An 18 mm socket is for the corresponding 18 mm external hexagon fastener. A 17 mm socket can damage the head or fail to seat; a 19 mm socket may slip. Verify the fastener's across-flats dimension instead of selecting by the nearest-looking socket.

VDE 3/8-inch drive versus 1/2-inch drive

A 3/8-inch square drive fits a matching handle or extension. A 1/2-inch-drive socket is not a direct replacement. When a job requires an insulated handle-and-socket system, choose compatible insulated components rather than improvising with an ordinary adapter.

What to confirm for institutional buying

Before placing a project or maintenance-store order, check the model, sale quantity, current GST-inclusive amount, tax invoice details, intended use, delivery pincode and any required technical or certification documentation. The exact listing can be used to request product clarification before purchase.

Frequently Asked Questions

1. Is STMT77818-23B an 18 mm or a 3/8-inch socket?

Both measurements apply to different interfaces. The socket fits an 18 mm external hexagon fastener and connects to a 3/8-inch square-drive tool.

2. What is the overall length of this STANLEY VDE socket?

The seller-hosted technical chart lists 45 mm overall length, with D1 at 28.7 mm and D2 at 23 mm.

3. What material is specified for this socket?

The product chart identifies chrome-vanadium steel (CrV). It does not establish an impact-tool rating or a numerical torque capacity.

4. Does the socket have a 1,000 V designation?

Yes. The seller-hosted product chart lists 1,000 V insulation. Exact-SKU certification and permitted-use documentation should be confirmed when needed for regulated or potentially hazardous electrical work.

5. Can I use it with an ordinary 3/8-inch ratchet?

The square-drive fit may match, but an ordinary uninsulated ratchet does not make an insulated tool system. For electrical-risk work, follow your approved tool-system and safety requirements.

6. Is this suitable for an impact wrench?

An impact rating was not verified for this exact model. Do not use it with a powered impact wrench unless STANLEY explicitly confirms compatibility.

7. How many sockets are included in the Indus MegaMart order?

The current listing does not clearly state a pack count. Confirm the selling quantity with Indus MegaMart before ordering or comparing prices.

8. Can I order when available stock is zero?

Yes. Under Indus MegaMart's ordering policy, orders and payment remain possible at zero stock. The stated delivery window is 7–14 days when the quantity ordered exceeds available stock; check your destination pincode.

9. Is GST included, and will I receive an invoice with GST details?

The national product listing shows a GST-inclusive price and separate tax amount. Indus MegaMart's generated invoices include the company's GST number.

10. Where can I buy STMT77818-23B for Goa delivery?

Use the exact national product listing, check the current offer and pincode, and proceed with the purchase once the 18 mm size, 3/8-inch drive and selling quantity match your requirement.
