Proto J5429MH 29mm 1/2 in Drive 6-point Hand Socket

Product Description

The PROTO J5429MH is a 29 mm, 6-point hand socket with a 1/2 inch drive, built for professional-grade fastener work. Chrome-plated finish resists corrosion and makes the socket easy to wipe clean in shop or field conditions. The 6-point geometry delivers full-contact engagement on hex fasteners, reducing the risk of rounding under high torque. Standard length profile fits most 1/2 inch drive ratchets and breaker bars without clearance issues. Meets ASME B107.5 standards for socket tools, making it a reliable choice for mechanics, maintenance technicians, and industrial service professionals who depend on consistent performance.

This socket suits residential, commercial, and industrial service applications where 29 mm fasteners are common — including automotive, heavy equipment, HVAC unit assembly, pump and motor servicing, and general mechanical maintenance. The 1/2 inch drive pairs with standard ratchets, torque wrenches, and impact-rated extensions found in most professional toolboxes. Its compact standard-length design allows use in moderately confined spaces where deep sockets are unnecessary.

Key Features

• 29 mm socket size for direct fitment on metric hex fasteners
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• 6-point contact geometry reduces fastener rounding under load
• Chrome-plated finish for corrosion resistance and easy cleaning
• Standard length profile for general-purpose use
• Meets ASME B107.5 socket tool standards

Compatibility

Designed as a standard 1/2 inch drive hand socket compatible with any 1/2 inch drive ratchet, torque wrench, breaker bar, or extension bar following ASME B107.5 drive dimensions.

Installation Notes

This socket is installed and removed by hand using a compatible 1/2 inch drive handle — no permanent mounting is required. Verify the fastener size before applying torque to avoid slippage or damage. Do not use hand sockets on impact drivers unless the socket is impact-rated. Inspect the socket for cracks or wear before each use, and replace if the drive square or socket bore shows visible deformation.
