Proto J07527MLT Impact Socket 3/4 in Drive 27mm 12-point

Product Description

The PROTO J07527MLT is a 12-point impact socket designed for heavy-duty fastener work in professional trade and industrial environments. Built from chrome-finished steel, it accepts a 3/4 inch drive and fits 27mm fasteners with an overall length of 3.5 inches. The 12-point geometry provides more contact positions around the fastener head, which is useful when working in tight rotational clearances. This socket is sized for applications where standard 1/2 inch drive tools lack the torque capacity needed, making it a common choice for HVAC equipment installation, large mechanical assemblies, and structural fastener work.

The J07527MLT is suited for commercial and industrial service work where 27mm fasteners appear on equipment mounts, flanges, and structural connections. It pairs with 3/4 inch drive impact wrenches and ratchets used by mechanical contractors, millwrights, and HVAC installers working on larger equipment. The chrome finish resists corrosion in typical shop and field environments. Its 3.5 inch overall length provides reach in recessed fastener positions without excessive extension.

Key Features

• 3/4 inch drive accepts standard 3/4 inch impact wrenches and ratchets
• 27mm socket size for metric fastener applications
• 12-point design allows engagement at more rotational positions
• 3.5 inch overall length for reach in recessed fastener locations
• Chrome-finished steel construction for corrosion resistance in field use

Compatibility

Designed as a direct-fit impact socket for use with 3/4 inch drive impact wrenches, air ratchets, and manual drive tools requiring 27mm metric socket size.

Installation Notes

Installation and fastener work using this socket should be performed by qualified mechanical tradespeople following applicable torque specifications for the fastener and joint type being serviced. Confirm the drive tool and socket are rated for the torque output being applied before use. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
