STANLEY 1-86-511 11mm 6-Point Socket, 1/2-Inch Drive in Chennai - Pack of 6

Confirm the Size and Drive Before Ordering

For this model, 11 mm is the size of the hexagonal nut or bolt head that fits inside the socket. 1/2 inch refers to the square-drive connection for a compatible hand ratchet, breaker bar or other suitable manually operated socket-drive tool. The two measurements describe different ends of the socket; an 11 mm opening does not mean that the drive is 11 mm.
The six-point opening is designed for hex fasteners. STANLEY's Maxi-Drive design is intended to help reduce fastener rounding when the correct socket is used. An accurately fitting socket can be particularly useful when a workshop must remove or refit several fasteners of the same metric size. Confirm the fastener's actual across-flats measurement rather than relying only on the nominal bolt thread diameter.

STANLEY 1-86-511 Technical Specifications

This is a standard socket, not a deep socket and not a complete socket-and-ratchet set. A compatible drive handle or extension is selected separately according to the job. The manufacturer's individual product listing describes one socket; the six-piece pack is Indus MegaMart's own displayed selling configuration.

Applications for Workshop and Maintenance Teams

The 1-86-511 is relevant wherever a correctly sized 11 mm hex nut or bolt head must be turned using a manual 1/2-inch-drive setup. Typical selection contexts include machine-tool maintenance, mechanical equipment assembly, service benches and routine workshop fastening. Its suitability depends on the fastener actually being 11 mm across flats, adequate access around the head and the torque limitations of the overall hand-tool assembly.

For Maintenance and Stores Procurement

A maintenance store stocking repeated 11 mm socket requirements can use the exact model number to avoid mixing it with nearby 10 mm or 12 mm sizes. Ordering by 1-86-511, not just “STANLEY socket”, reduces confusion between standard and deep variants, six-point and twelve-point profiles, and different drive connections. For repeated requirements, calculate quantity in the supplier's six-piece selling packs, not in isolated pieces.

For Manual Assembly and Repair

Choose this socket when a standard-length tool can reach the 11 mm fastener without a deep recess or long exposed stud. Use a compatible 1/2-inch square-drive hand tool, confirm positive engagement before applying force and follow the equipment or fastener manufacturer's tightening instructions. A separate calibrated torque wrench is required where a specified torque must be achieved and verified.

Standard 6-Point Socket: What It Is—and What It Is Not

A six-point socket has six internal contact positions for a six-sided fastener. This profile emphasizes contact with a hex head and, together with the Maxi-Drive design, is intended to limit damage from corner loading. A twelve-point socket can offer more alignment positions, but it is a different tool profile and should not be substituted simply because both are labelled 11 mm.
A deep socket is often the more appropriate class for a nut on a long protruding stud or a deeply recessed fastener. An extension increases reach but does not increase the internal depth of a short socket. Confirm available working clearance before deciding between standard and deep designs.
STANLEY specifies the 1-86-511 for manual use. It should not be promoted or selected as an impact-rated socket for a powered impact wrench. Likewise, the 1/2-inch drive size is a connection dimension, not an approved torque rating. When torque control matters, confirm tool ratings and the fastener specification rather than treating the socket as a measuring instrument.

Frequently Asked Questions

1. Is STANLEY 1-86-511 an 11 mm socket or a 1/2-inch socket?

Both measurements are correct but refer to different interfaces. 11 mm is the opening for the hex fastener; 1/2 inch is the square drive that fits a compatible manual ratchet or handle.

2. Is the listed Indus MegaMart price for one socket or six?

The current Indus MegaMart offer is a six-piece pack of the same 11 mm model. Check the live GST-inclusive pack price and purchase quantity on the National Product Detail Page. The manufacturer's individual model specification should not be mistaken for the merchant's selling pack.

3. Can I buy the 1-86-511 when available stock is zero?

Yes. Indus MegaMart's ordering policy accepts orders and payment even at zero available stock. In that case, the stated delivery window is 7–14 days, subject to your delivery PIN code and order confirmation.

4. What is the difference between this 6-point standard socket and an 11 mm deep socket?

This is a standard-depth socket for accessible hex fasteners. A deep socket provides greater internal reach for some recessed fasteners or protruding studs. Check the actual working clearance and tool geometry before selecting either type.

5. Can I use STANLEY 1-86-511 with a powered impact wrench?

It is identified by STANLEY as a socket for manual use. Do not treat it as an impact-rated accessory. Choose an explicitly impact-rated socket for powered impact applications.

6. Is a ratchet, extension or torque wrench included in the six-piece offer?

The product is listed as a pack of six sockets, not as a socket-handle kit. Select and purchase compatible drive handles, extensions or torque tools separately where required.

7. What does Maxi-Drive mean on this socket?

Maxi-Drive is STANLEY's socket engagement design, described by the manufacturer as helping to reduce rounding of fasteners. It is not a promise of unlimited torque capacity or guaranteed protection for damaged fasteners.

8. Does this model have a verified torque rating or fixed warranty term?

The published exact-model manufacturer information does not specify a numeric torque rating or a product-specific warranty duration. Use appropriate hand tools within their published limitations and check the applicable warranty terms before ordering if coverage is important.

9. How do I check price, GST and delivery for Chennai?

Open the exact STANLEY 1-86-511 listing, review the current GST-inclusive price for the six-piece pack, enter your Chennai PIN code and follow the purchase process. Indus MegaMart issues invoices containing its company GST number.
