Proto J5546HL Deep Hand Socket 1-7/16 in 6-pt 3/4 Drive

Product Description

The PROTO J5546HL is a deep hand socket designed for high-torque fastener removal and installation in demanding trade environments. Built from alloy steel with a satin finish, it accepts a 3/4 inch drive and fits a 1-7/16 inch fastener with a 6-point contact pattern. The deep length design — 3.5 inches overall — provides clearance for recessed or extended fastener heads that standard-depth sockets cannot reach. The 6-point geometry maximizes contact on hex fasteners, reducing the risk of rounding under load. This socket meets ASME B107.110-2012 standards, making it appropriate for professional use in mechanical, industrial, and heavy equipment applications.

This socket is suited for mechanical contractors, millwrights, equipment technicians, and industrial maintenance professionals working on heavy machinery, structural fasteners, or any application requiring a 3/4 inch drive tool with deep reach. The 1-7/16 inch size is common in HVAC equipment frames, large-diameter pipe flanges, and heavy-duty mechanical assemblies where fasteners are recessed or sit on extended studs.

Key Features

• Deep length at 3.5 inches overall — reaches recessed and extended fasteners
• 6-point contact geometry reduces fastener rounding under high torque
• Alloy steel construction for durability in heavy-duty applications
• Satin finish resists glare and provides corrosion resistance
• Meets ASME B107.110-2012 standards for professional-grade hand tools
• 3/4 inch drive fits standard heavy-duty drive tools and torque wrenches

Compatibility

Designed as an OEM-style deep hand socket for use with 3/4 inch drive ratchets, breaker bars, and torque wrenches in professional and industrial service applications.

Installation Notes

Installation and removal should be performed by a qualified mechanic or maintenance technician using a calibrated torque wrench when fastener torque specifications apply. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage or damage. Follow applicable ASME or equipment manufacturer guidelines for fastener torque procedures. Not tether-capable — use with caution in elevated or overhead work environments where dropped-tool hazards exist.
