Klein Tools 33809 Sae Impact Socket Set 10 Piece 3/8 Drive

Product Description

The KLEIN TOOLS 33809 is a 10-piece SAE impact socket set built for trade professionals who need fast, reliable fastener access on the job. Constructed from cold-forged, heat-treated chrome molybdenum (Cr-Mo) steel, these sockets are engineered to handle the high torque demands of impact drivers without cracking or rounding. The set covers nine of the most common SAE sizes from 1/4 inch through 3/4 inch and includes a 3/8-inch drive sleeve with carabiner for organized, hands-free carrying on tool belts, bags, or backpacks. Industry-standard color-coded rings and bold stamped markings make size identification fast and accurate, even in low-light or high-pressure conditions.

The 33809 is suited for residential and commercial mechanical work where SAE fasteners are standard. Electricians, HVAC technicians, plumbers, and general contractors will find the size range useful for equipment installation, panel work, mechanical connections, and fixture mounting. The included carabiner sleeve keeps the set organized and accessible on the go, reducing time spent searching for the right socket during active installs or service calls.

Installation Notes

Impact-rated sockets should only be used with impact drivers or impact wrenches, not standard hand ratchets where prolonged stress cycling may occur. Verify the drive size of your impact tool matches the 3/8-inch drive before use. Inspect sockets for cracks or deformation before each use and replace any damaged socket immediately. Store sockets in the provided sleeve to prevent loss and maintain organization on the job site.
