3/4 Inch Drive Extension Set

This TEKTON set supplies three extensions in 4, 8, and 16 inch lengths for 3/4 inch drive tools. The range lets you reach past obstructions and into tight, narrow spaces when working with sockets. It is built for mechanics and technicians who service heavy equipment, trucks, tractors, and large machinery where extra reach is essential.

Three Lengths for Deep Access

The 4 inch extension handles shallow recesses while the 8 and 16 inch pieces span deeper cavities without forcing awkward angles. Spring-loaded retaining balls latch sockets securely and detent grooves with through-holes allow locking pins for positive retention. Knurled bands give fingertip grip for starting or spinning loosened fasteners by hand.

Chrome-Plated Durability

Polished chrome plating resists corrosion and wipes clean after exposure to shop fluids. Beveled drive ends guide the extension smoothly onto ratchets or breaker bars and radiused interior corners reduce stress concentrations that can lead to cracking. The set requires a 3/4 inch drive ratchet or breaker bar and compatible sockets, freeing you from improvising with smaller drive adapters.

Questions about this item

Will the 3/4 in. drive extensions fit my existing 3/4 in. drive ratchet and sockets?

Yes, the 3/4 in. drive size matches standard 3/4 in. drive tools; the beveled drive end guides the extension onto the ratchet and the spring-loaded ball retains sockets securely.

How can I verify the extensions lock properly onto my drive tool after attaching them?

The detent grooves engage the ratchet's retention mechanism and the drilled through-hole accepts a retaining pin for a positive mechanical lock you can feel and see.

Does the set include the retaining pins for the through-holes or do I need to supply them?

The set includes three extensions — 4 in., 8 in., and 16 in. — with knurled grip bands and chrome-plated finish; retaining pins are not included and must be purchased separately.
