1/2" Drive 3-in-1 Lineman 9/16" x 3/4" 12 Point Slotted Deep Impact Socket

New!
GWLS34916J
The GEARWRENCH 9/16" x 3/4" Lineman 3-in-1 12 Point Slotted Deep Impact Socket combines multiple utility hardware functions into one efficient tool. The dual-size design works with common 9/16" and 3/4" fasteners, while a precision-machined 1/4" slot engages eye bolts on most hotline clamps. A thin-wall, nose-down profile helps access recessed and hard-to-reach hardware, and the deep socket design provides additional clearance for protruding fasteners and utility hardware. Double-hex geometry maximizes contact on 12-point fasteners while remaining compatible with 6-point hardware, and the off-corner loading design helps reduce fastener rounding. Proprietary heat treatment delivers up to 10X longer service life than standard sockets, while Hi-Viz markings and color-coded bands allow for quick identification in the field. Backed by a Full Lifetime Warranty.

  • Frequently Asked Questions
    What makes this a 3-in-1 impact socket?
    This socket combines two common socket sizes with an integrated hotline clamp slot, helping reduce tool changes and improve efficiency on utility jobs.
    What is the integrated hotline clamp slot used for?
    The precision-machined 1/4" slot is designed to engage eye bolts on most hotline clamps, allowing the socket to perform multiple utility hardware functions.
    What are the benefits of the deep socket design?
    The deep design provides additional clearance for protruding fasteners, long threaded hardware, and utility applications where a standard-depth socket may not fit.
    Why does the socket use a thin-wall, nose-down profile?
    The thin-wall design improves access to recessed and hard-to-reach hardware, while helping ensure smooth engagement on 9/16" nuts.
    Will this socket work with both 12-point and 6-point fasteners?
    Yes. The double-hex design is optimized for 12-point fasteners while maintaining compatibility with many 6-point applications.
