Sk 4524 3/8 in Drive Socket Wobble Extension Set 4 Pc

Product Description

The SK 4524 is a four-piece, 3/8 inch drive socket wobble extension set designed for technicians who need off-angle fastener access in tight or obstructed work areas. The set includes extensions in 3 inch, 6 inch, 8 inch, and 12 inch lengths, each with a wobble joint that allows the drive to flex off-axis without losing socket engagement. The chrome-plated finish resists corrosion and makes cleanup straightforward after use. HVAC, plumbing, and electrical trades all reach for wobble extensions when working around ductwork, pipe runs, panel cabinets, or equipment frames where a straight-line drive is not possible.

This set fits standard 3/8 inch drive ratchets and torque wrenches and is suited for both residential and light commercial service work. The four included lengths cover close-quarters access with the 3 inch piece up through extended reach with the 12 inch piece, giving a technician the right extension for most confined-space fastening situations without switching drive sizes. The set is packaged as a single unit and is commonly used by HVAC technicians, plumbers, pipefitters, and electricians during equipment installation and service calls.

Installation Notes

A licensed technician or journeyman should confirm fastener torque requirements before using a wobble extension in applications where exact torque is critical, as wobble joints can reduce torque transfer efficiency at high angles. Ensure the socket is fully seated on the extension before applying load to avoid slippage. When working near energized electrical components, de-energize and lock out the equipment per applicable NFPA 70E and OSHA lockout/tagout procedures before using hand tools in the work area.
