The ball end tip allows fastener engagement at up to a 30-degree angle, useful when working in tight or obstructed spaces. Shafts are manufactured from chrome vanadium molybdenum steel for hardness and resistance to wear under repeated torque loads. The long-arm design extends reach into deep recesses and increases torque leverage compared to standard-arm keys. This set is suited for mechanical and equipment technicians who need a complete SAE inch hex key range in a single kit.\u003c\/p\u003e\u003cp\u003eThis hex key set covers the most common SAE fractional and decimal inch sizes used in industrial equipment, HVAC machinery, electrical panels, pump assemblies, and general mechanical work. The 13 included sizes address fastener sizes from small set screws to larger cap screws, making the set practical across a wide range of service calls. The long-arm configuration is particularly useful when accessing set screws on motor shafts, blower wheel hubs, and similar recessed fasteners found in mechanical and HVAC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13 SAE sizes included: 0.05 in, 5\/64 in, 3\/32 in, 7\/64 in, 1\/8 in, 9\/64 in, 5\/32 in, 3\/16 in, 7\/32 in, 1\/4 in, 5\/16 in, 3\/8 in\u003c\/li\u003e\n\u003cli\u003eBall end tip allows off-axis engagement for use in confined or angled access areas\u003c\/li\u003e\n\u003cli\u003eLong-arm design provides extended reach and increased torque leverage\u003c\/li\u003e\n\u003cli\u003eChrome vanadium molybdenum steel construction for durability and hardness\u003c\/li\u003e\n\u003cli\u003eFull SAE range from 0.05 inches to 3\/8 inches in a single set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SAE inch-size internal hex fasteners across mechanical, HVAC, electrical, and plumbing equipment service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAlways select the correctly sized hex key for the fastener to avoid rounding the socket. De-energize or lock out equipment before loosening or tightening fasteners on powered machinery.
