STANLEY STMT89319-8B 19mm 6-Point Standard Socket, 3/4-Inch Drive - Lucknow

Key Specifications

The listed overall length does not necessarily equal the available internal clearance for a protruding stud.

What Do 19mm and 3/4-Inch Drive Mean?

The 19 mm measurement refers to the nominal dimension across the parallel flats of a compatible external-hexagonal nut or bolt head. It does not describe the bolt's threaded diameter.
The 3/4-inch measurement describes the socket's square-drive connection. It determines which ratchet, breaker bar, torque wrench or extension can connect to the socket.
A 19 mm socket with a 1/2-inch square drive is not the same drive configuration as this product.
The six-point opening is designed for an external hexagonal fastener, not for a screw with an internal Allen or hex-bit recess.

Why Choose a Six-Point Standard Socket?

The six-point design engages the flats of a correctly sized external-hexagonal fastener. Proper engagement helps maintain stable contact during controlled manual fastening.
Its standard-depth body can be suitable when a nut or bolt head is accessible without needing the additional internal reach of a deep socket.
STANLEY catalogue information identifies this product family as chrome-vanadium steel and intended for manual operation.
Where an application specifies measured tightening torque, use an appropriately rated calibrated torque wrench and follow the applicable fastener or equipment manufacturer's instructions.

Applications of STANLEY STMT89319-8B

The 19 mm standard socket can be considered for compatible fastening requirements in industrial machinery maintenance, equipment installation, mechanical workshops and fleet servicing.
Its 3/4-inch square-drive configuration may be particularly relevant where the existing manual tool system uses that larger drive interface.
Actual suitability depends on the fastener dimensions, tool accessibility, working procedure and required drive configuration.
A different square-drive size, deep socket or impact-rated socket may be necessary for other applications.

Four Checks Before Ordering or Using

1. Confirm fastener size: Measure the external-hexagonal fastener head to establish a correct 19 mm across-flats fit.
2. Check drive compatibility: Use a compatible 3/4-inch square-drive manual ratchet, breaker bar or torque wrench.
3. Verify access and depth: Confirm that the standard socket can seat completely. The 50 mm overall length does not establish its internal stud clearance.
4. Confirm the pack and tool class: Indus MegaMart sells this product in a four-piece pack. For powered impact-wrench use, choose an appropriately impact-rated socket.

Inspect the socket and related drive tools before use. Do not force a mismatched socket onto rounded or damaged fasteners.
