Proto J4718LT Deep Hand Socket 9/16 Inch 12-point

Product Description

The PROTO J4718LT is a 9/16 inch, 12-point deep hand socket designed for use with a 1/4 inch drive ratchet or extension. The deep profile allows it to reach fasteners that are recessed or seated on longer studs where a standard-depth socket would not fully engage. The chrome-plated finish resists corrosion and makes the socket easier to wipe clean after use. This socket is a standard tool for licensed mechanics, HVAC technicians, electricians, and plumbers who need reliable hand-tool access in tight or deep fastener applications.

This socket fits typical residential and light commercial service work where 1/4 inch drive tools are practical — such as panel work, equipment access covers, fan blade assemblies, and fastener-dense areas in mechanical systems. The 12-point design allows engagement at 30-degree increments, giving more positional options in confined spaces. It is suited for both bench work and field service calls where compactness and reach both matter.

Key Features

• 9/16 inch socket size for common fastener sizes found in HVAC, plumbing, and electrical equipment
• 12-point geometry allows engagement every 30 degrees, useful in tight or obstructed spaces
• Deep length profile reaches recessed or stud-mounted fasteners that standard sockets cannot fully seat on
• 1/4 inch drive fits compact ratchets and extensions common in field service kits
• Chrome-plated finish resists corrosion and simplifies cleaning

Compatibility

Designed as an OEM-style hand socket for use with standard 1/4 inch drive ratchets, extensions, and torque wrenches.

Installation Notes

This socket is a hand-tool accessory installed by any trade professional using 1/4 inch drive equipment. Before use, confirm the drive detent engages fully and the socket seats flush on the fastener. Avoid using hand sockets with impact drivers, as hand-socket chrome finishes are not rated for impact use. Store separately from impact sockets to prevent misidentification in the field.
