Proto J49905/32ST Hand Hex Bit Socket 3/8 in Drive

Product Description

The PROTO J49905/32ST is a hand hex bit socket designed for 3/8 inch drive ratchets and extensions. It accepts a 5/32 inch hex bit and delivers a total overall length of 1-13/16 inches, with a bit length of 3/4 inches. Built for professional hand-tool use, this socket suits technicians and tradespeople who need precise hex fastener drive capability in tight or standard-access applications. The compact overall length makes it practical for work in confined spaces where a full-depth socket would be impractical.

This hex bit socket is suited for residential and commercial service work across HVAC, electrical, plumbing, and general mechanical applications where 5/32 inch hex fasteners are encountered. It is compatible with any standard 3/8 inch drive hand tool — including ratchets, torque wrenches, and extensions — making it a versatile addition to a professional service kit. Typical use cases include equipment panel fasteners, set screws, and hex-head machine bolts common in mechanical and electrical assemblies.

Key Features

• 3/8 inch drive compatibility for use with standard ratchets, extensions, and torque wrenches
• 5/32 inch hex bit size for precise engagement with matching fasteners
• Compact 1-13/16 inch overall length suited for confined-space work
• 3/4 inch bit length provides adequate fastener engagement depth

Compatibility

Designed for use with standard 3/8 inch drive hand tools including ratchets, breaker bars, torque wrenches, and extensions. Suitable for any application requiring a 5/32 inch hex bit socket in a hand-tool drive configuration.

Installation Notes

This socket is intended for hand-tool use only and should not be used with impact drivers or pneumatic tools unless explicitly rated for impact service. Before use, confirm the drive square and socket are fully seated and free of debris to prevent rounding of the fastener or socket. Always select the correct hex size to avoid fastener damage. Applicable work should follow any relevant trade codes or equipment service documentation for torque requirements.
