Proto J49905/32XL Hex Bit Socket 3/8 in Drive 5/32 in

Product Description

The PROTO J49905/32XL is a long hex bit socket designed for hand-tool use in professional trade and industrial settings. It accepts a 3/8 inch square drive and fits a 5/32 inch hex fastener. The overall length of 6-3/32 inches and a 5 inch bit length make this socket well suited for reaching recessed fasteners where a standard-length socket would fall short. Electricians, HVAC technicians, and plumbers reach for long-series hex bit sockets when servicing equipment with deeply set set screws, allen-head fasteners, or hex-drive cap screws in confined assemblies. This socket is a single-piece hand-tool item with no power-tool rating implied.

This long hex bit socket is used across residential and commercial service work wherever a 5/32 inch hex fastener needs to be driven or removed from a deep or obstructed location. Typical applications include panel assembly, equipment access covers, fan blade set screws, valve packing nuts, and structural fasteners inside enclosures. It fits standard 3/8 inch drive ratchets, extensions, and torque wrenches commonly found in HVAC, plumbing, and electrical service kits.

Key Features

• Long series design at 6-3/32 inches overall length for reaching recessed fasteners
• 5 inch bit length provides extended reach beyond standard hex bit sockets
• 5/32 inch hex size (3.970 mm) fits common set screws and allen-head fasteners
• 3/8 inch square drive is compatible with standard ratchets, extensions, and torque wrenches
• Lightweight at 0.12 pounds — minimal added weight in a service bag or tool kit

Compatibility

Designed as an OEM-style replacement or service addition for any 3/8 inch drive hand-tool set requiring a long hex bit socket in the 5/32 inch hex size.

Installation Notes

This socket is intended for hand-tool use with a 3/8 inch drive ratchet or torque wrench. Always verify the fastener hex size before applying torque to avoid rounding the drive recess. Follow applicable equipment manufacturer guidelines and relevant codes when servicing electrical panels, HVAC equipment, or plumbing assemblies. De-energize or shut off the equipment being serviced before using any hand tool on internal fasteners.
