Stanley STH71839 Folding Hex Key Set Metric Sae 2 Pack

Product Description

The STANLEY STH71839 is a 2-pack folding hex key set covering both metric and SAE sizes, built for trade professionals who need a reliable, compact wrench solution on the job. The set features durable composite construction with rubber side inserts that provide a secure grip during use. A chamfered entry edge guides the key smoothly into fastener sockets, reducing cam-out and speeding up fastener engagement. Size markings are printed directly on each hex key body for fast identification without guesswork. At 2.96 pounds per set, the unit is solid without being burdensome on a tool belt or service bag.

This hex key set is suited for residential and light commercial service work across HVAC, plumbing, electrical, and general mechanical applications. The folding design keeps all sizes organized and accessible within a single compact frame, making it practical for service techs working in tight equipment rooms or confined utility spaces. The dual-system coverage of both metric and SAE sizes reduces the need to carry two separate sets on a call.
