B38K Llc 151-015 4-way Stem Key Square Stem

Product Description

The B38K LLC 151-015 is a 4-way stem key designed to fit square stems commonly found in faucet and valve repair applications. The tool provides four drive sizes in a single compact unit, covering 1/4 inch, 9/32 inch, 5/16 inch, and 11/32 inch square stem profiles. It comes packaged on a vinyl display card with a storage pouch for job-site organization. Plumbers and service technicians reach for this type of tool when turning off water supply stops, angle valves, and similar fixtures that require a square-drive stem key rather than a standard shutoff handle. The all-in-one design reduces the need to carry multiple individual keys.

This stem key is suited for residential and light commercial plumbing service work. It is particularly useful when servicing faucets, flush valves, and repair parts in bathrooms, kitchens, and utility areas. The four stem sizes address the most common square-stem profiles encountered in standard plumbing fixture repair, making it a practical addition to a service technician's tool kit. The vinyl display and included storage pouch support organized storage in a parts van or service bag.

Installation Notes

Installation and use of this tool should be performed by a licensed plumber or qualified service technician familiar with faucet and valve repair procedures.

Verify the correct stem size before applying torque to avoid rounding the stem head. Work performed on plumbing systems must comply with applicable local plumbing codes and the International Plumbing Code where adopted.
